If skype crashes, it's a bug in skype. Please ask them to fix it, or support ALSA properly. ---------------------------------------------------------------------- Hetfield - 07-01-05 22:56 ---------------------------------------------------------------------- from a point of view you're right, but, from the other, you're not. if it crashes with aoss this means aoss is not fully transparent for an application. that's why i asked for a driver low-level management. ---------------------------------------------------------------------- pzad - 07-02-05 18:53 ---------------------------------------------------------------------- In aoss is bug. I found one (skype doesn't crash), but still can not get it work - there is probably another one. ---------------------------------------------------------------------- Hetfield - 07-02-05 20:11 ---------------------------------------------------------------------- very good, i was sure of aoss/ dmix system bug. can i get your fixes in order to check here? ---------------------------------------------------------------------- pzad - 07-02-05 21:47 ---------------------------------------------------------------------- With this patch skype works with aoss, but for now not with dmix (it can work dirrectly with hw or plughw - this is not usefull for now). ---------------------------------------------------------------------- Hetfield - 07-03-05 09:25 ---------------------------------------------------------------------- i tested your patch. it doesn't crash skype, nor i get "error with audio device" as before but i can't hear nothing, as you said.. ready to test new fixes :) ---------------------------------------------------------------------- pzad - 07-03-05 14:09 ---------------------------------------------------------------------- I can make skype work with dmix (but only if dmix is mono). In this mode it works ok. Problem is skype doesn't check return value (channel count and assume mono is supported, but this is not case when dmix is used in stereo mode). ---------------------------------------------------------------------- Hetfield - 07-03-05 15:57 ---------------------------------------------------------------------- i haven't undestood if the problem (only in mono) is fixed with another patch (and so, please submit here) or if it already works actually. how to check the dmix mono setting? however i submitted a skype ticket linking this thread, as soon as i got an answer i'll post here, hoping to fix this problem as soon as possibile. the question is: shouldn't skype have the same problem with pure oss driver? i mean..if it assume mono and not stereo without checks, what's the difference with dmix? this is what i thought when i opened this bug, dmix is not fully transparent to applications, or, apart the init bug, it should let apps work as pure oss access. i'm not an alsa expert, never read the code, i may fail of course, but this is my suspect. good work. ---------------------------------------------------------------------- pzad - 07-04-05 11:53 ---------------------------------------------------------------------- aoss.patch - this will make skype work in mono mode. You need to put channels 1 to dmix.conf and dsnoop.conf. In pure oss mode skype ask for mono 48000 kHz and it got this. In dmix it got 48000 but stereo. ---------------------------------------------------------------------- Hetfield - 07-04-05 14:02 ---------------------------------------------------------------------- i'm sorry, i searched the web for a while but didn't got that mono config. however, if i have understood well, i would have mono for all apps and not only skype, and that's not good. i'm still waiting for skype support response..i'll keep you updated. ---------------------------------------------------------------------- tiwai - 07-08-05 12:16 ---------------------------------------------------------------------- Doesn't plug layer work for mono conversion? ---------------------------------------------------------------------- Hetfield - 07-08-05 12:27 ---------------------------------------------------------------------- i think i configured that in a wrong way. but i don't want mono sound, that's why i didn't search a lot. ---------------------------------------------------------------------- Hetfield - 07-17-05 10:25 ---------------------------------------------------------------------- another problem found: kiax ( http://kiax.sf.net ), another voip client, doesn't work with aoss. it uses portaudio library ( oss support only). when i start with "aoss kiax" program starts, but show nothing, cpu usage is 100%. seems an endless loop. i waited some mins, nothing change. another issue with aoss so :( ---------------------------------------------------------------------- rlrevell - 07-17-05 10:29 ---------------------------------------------------------------------- PortAudio can use ALSA too. Otherwise it would not be very portable... ---------------------------------------------------------------------- rlrevell - 07-17-05 10:46 ---------------------------------------------------------------------- Actually this might be useful, if it's the same problem affecting skype. What does strace -p PID show you, where PID is the kiax PID? ---------------------------------------------------------------------- Hetfield - 07-17-05 11:10 ---------------------------------------------------------------------- rlrevell, for alsa/portaudio: http://sourceforge.net/forum/forum.php?thread_id=1276778&forum_id=448020 i attached a long log. please check. however: cat log|grep dsp stat64("/dev/dsp697", 0xbfbcb3a0) = -1 ENOENT (No such file or directory) stat64("/dev/dsp698", 0xbfbcb3a0) = -1 ENOENT (No such file or directory) stat64("/dev/dsp699", 0xbfbcb3a0) = -1 ENOENT (No such file or directory) stat64("/dev/dsp700", 0xbfbcb3a0) = -1 ENOENT (No such file or directory) stat64("/dev/dsp701", 0xbfbcb3a0) = -1 ENOENT (No such file or directory) it's abvoius it keeps searching for free dsp. (in log you'll find it searches in proc too...) even if dsp is unused. ---------------------------------------------------------------------- rlrevell - 07-17-05 19:41 ---------------------------------------------------------------------- What does "file /dev/dsp" tell you? ---------------------------------------------------------------------- Hetfield - 07-17-05 19:50 ---------------------------------------------------------------------- root@blight ~ # file /dev/dsp /dev/dsp: symbolic link to `sound/dsp' root@blight ~ # file /dev/s Display all 137 possibilities?

Presumably it tried to open 0 through 696 before this. So you need to get an strace of when the process first starts up. ---------------------------------------------------------------------- Hetfield - 07-17-05 21:23 ---------------------------------------------------------------------- added new strace output. 600k...i hope you can find something interesting ---------------------------------------------------------------------- rlrevell - 07-17-05 22:21 ---------------------------------------------------------------------- Something (either in alsa-lib or the app) does not seem to be handling a timer correctly. After opening /dev/dsp, it tries to open some type of timer: open("/dev/snd/timer", O_RDONLY|O_NONBLOCK) = 9 ioctl(9, 0x80045400, 0xbf822ecc) = 0 ioctl(9, TIOCSPGRP, 0xbf822ed0) = 0 ioctl(9, 0x80045400, 0xbf8232fc) = 0 Then the ioctl to start the timer returns -EBUSY: ioctl(9, SNDCTL_TMR_START or TCSETS, 0x82676e8) = -1 EBUSY (Device or resource busy) Then it does some more ioctls on the timer: ioctl(9, TIOCSTI, 0xbf8234d0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf8235f0) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, TIOCSTI, 0xbf823630) = 0 ioctl(9, 0x54a1, 0xb729aa08) = 0 read(9, "\0\0\0\0\0\0\0\0", 8) = 8 Then we get EAGAIN trying to read the timer, which causes it to give up and try /dev/dsp1, and so on. read(9, 0xbf8239c0, 8) = -1 EAGAIN (Resource temporarily unavailable) close(9) = 0 But this also fails because it performs the exact same sequence of operations on the timer. I suspect that the return value of the ioctl to start the timer was not checked, so the app just assumes the timer was started. Of course it's also completely broken for the app to keep opening non-existent /dev/dsp* in a loop like that. ---------------------------------------------------------------------- Hetfield - 07-17-05 23:28 ---------------------------------------------------------------------- ok ok, but maybe you missed my point: why it work perfectly with plain oss and not with aoss? that's the same issue for skype..aoss is not a FULLY transparent bridge between apps and driver translation. apart some fatal bugs (seg fault fixed in this thread) there seems to be some hidden little holes to fill. i'll be happy to test any patch or fix ---------------------------------------------------------------------- rlrevell - 07-17-05 23:43 ---------------------------------------------------------------------- Well, it's not a bug-for-bug compatible emulation. There are always areas in any API that are ambiguous or implementation dependent. The fact that it works with another OSS implementation does not rule out an application bug. Most of the cases we have seen so far where aoss breaks something involve buggy apps, that just happen to work with OSS or the in kernel emulation. They are just as likely to fail under a different OSS implementation. For example skype assumes it gets 48KHz stereo, even though the stream is mono. Although this particular case is due to a quirk of dmix, it would also fail if the hardware only supported 48Khz mono. They just didn't bother to test it under an OSS implementation where this can happen. ---------------------------------------------------------------------- rlrevell - 07-18-05 03:33 ---------------------------------------------------------------------- That being said, after looking at the code a bit this is almost certainly a dmix bug. It would be nice to know what all those ioctls are. Any idea why strace can't resolve them? ---------------------------------------------------------------------- rlrevell - 07-18-05 06:04 ---------------------------------------------------------------------- I was not able to reproduce the bug; even when I had enabled dmix, the emu10k1 driver allocated separate voices for esd and kiax. But, I did find that the sound is terribly choppy with aoss, which did not happen with the in kernel OSS emulation. Also, I had to apply the alsa-oss patches from this bug report, otherwise kiax crashed on startup. These should be applied to CVS ASAP. ---------------------------------------------------------------------- rlrevell - 07-18-05 07:33 ---------------------------------------------------------------------- Maybe this is related (from the dmix docs). Do you have an .asoundrc or /etc/asound.conf? For using the dmix plugin for OSS emulation device, you have to set the period and the buffer sizes in power of two. For example, \code pcm.dmixoss { type dmix ipc_key 321456 # any unique value ipc_key_add_uid true slave { pcm "hw:0" period_time 0 period_size 1024 # must be power of 2 buffer_size 8192 # ditto } } ---------------------------------------------------------------------- Hetfield - 07-18-05 09:23 ---------------------------------------------------------------------- you have hardware mixing, so no problem for you. i'll attach my .asoundrc file, but i copied it from some howtos, so i guess it's clean ---------------------------------------------------------------------- rlrevell - 07-18-05 22:08 ---------------------------------------------------------------------- I cannot reproduce the problem as aoss + dmix does not use a timer on my system, due to hardware mixing being present. It actually seems to work (the choppiness was due to running under gdb), but for some reason it always gets 8000Hz for the sample rate, even if I comment it out of the sapleRates table, and set "rate 48000" in dmix.conf. Try running with ALSA_OSS_DEBUG=1 and post the output. Also uncomment these lines and recompile to enable debug output from kiax: kiax-0.8.4/lib/portaudio/pa_common/pa_lib.c~:#define DBUG(x) /* PRINT(x) */ kiax-0.8.4/lib/unixfuncs.c~://#define DBUG(...) fprintf(stderr, __VA_ARGS__) ---------------------------------------------------------------------- Hetfield - 07-21-05 19:55 ---------------------------------------------------------------------- i enabled both debug..here is result..hope you can debug it...

I think it's a dmix issue. I cannot reproduce it on my system, because I only have the emu10k1 to test with, but if you look at the logs it seems related to the use of PCM slave timers by dmix. It should be easy to reproduce with aoss + kiax (open source VOIP client) over dmix with any non-hardware mixing device. I think solving this bug could be key to resolving the aoss + skype issues, as we now have a similar open source app with which we can reproduce the bug. ---------------------------------------------------------------------- tiwai - 07-29-05 17:43 ---------------------------------------------------------------------- At first, make sure that you're using the latest alsa-lib. Some 100%-CPU-hog bugs were fixed in the recent release. Also, remove ~/.asoundrc once. The default configuration of dmix should be OK for aoss in the recent version, too. ---------------------------------------------------------------------- Hetfield - 08-01-05 10:20 ---------------------------------------------------------------------- deleting my .asoundrc file i have no more 100% cpu usage. where the problem is? i attacched my config file. however kiax doesn't work... it starts but i get (debug disabled actually) PortAudio error at opening separate input stream: Invalid device ID. lun ago 1 10:16:06 2005 IaxWrapper::event_text() Message: Type=3 Message=Can't start audio lun ago 1 10:16:06 2005 IaxWrapper::event_text() Message: Type=4 Message=iaxclient audio: Can't open Audio Device, we tried 5 times.
