I have already run alsamixer many times and tried every combination of muted and unmuted settings with all volumes maximized. With no volume settings muted, and all volume settings at maximum level, I still get no sound. Everything *looks* like it's working - output in the kernel log, xmms's display, everything. But I get no sound out of the built-in speaker or the headphone jack. I have tried the following: * Default install of Fedora Core 3; it recognized the sound card and installed module settings in /etc/modprobe.conf to load snd-intel8x0. But I never got any sound out of this default install no matter what I tried. * Custom compiled the 2.6.9 kernel with no patches except the software suspend 2 patch. This built the version of the ALSA drivers that come with 2.6.9. Still no sound. * Downloaded and compiled version 1.0.7 of the ALSA drivers and installed them. Still no sound. ====================================================================== ---------------------------------------------------------------------- bji - 11-21-04 02:55 ---------------------------------------------------------------------- Oh, I should mention that previously I had been using Debian unstable and the sound worked perfectly. I believe that the kernel version was 2.6.8 or 2.6.9 (unfortunately I have blown away that installation and can't get any information from it). ---------------------------------------------------------------------- bji - 11-21-04 03:16 ---------------------------------------------------------------------- Here's my /etc/modprobe.conf if it helps: # Ethernet alias eth0 8139too # USB alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd # ALSA alias char-major-116 snd alias snd-card-0 snd-intel8x0 options snd-intel8x0 index=0 install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || : remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0 # OSS/Free portion alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-slot 1 snd-card-1 # Intel Sound alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss ---------------------------------------------------------------------- bji - 11-21-04 03:19 ---------------------------------------------------------------------- Here are the modules that are installed after my system boots: Module Size Used by snd_pcm_oss 55208 0 snd_mixer_oss 19712 1 snd_pcm_oss snd_intel8x0 36924 1 snd_ac97_codec 76896 1 snd_intel8x0 snd_pcm 111240 3 snd_pcm_oss,snd_intel8x0,snd_ac97_codec snd_timer 34948 1 snd_pcm snd 61156 8 snd_pcm_oss,snd_mixer_oss,snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer soundcore 11360 1 snd snd_page_alloc 10504 2 snd_intel8x0,snd_pcm uhci_hcd 34960 0 ehci_hcd 37380 0 ipw2100 146372 0 ieee80211 35908 1 ipw2100 i915 86788 3 md5 4608 1 ipv6 272320 8 ds 19204 2 ipt_REJECT 7296 1 ipt_state 2176 1 ip_conntrack 45876 1 ipt_state iptable_filter 3200 1 ip_tables 18048 3 ipt_REJECT,ipt_state,iptable_filter dm_mod 62740 0 button 6928 0 battery 9220 0 ac 5124 0 yenta_socket 20864 0 pcmcia_core 67396 2 ds,yenta_socket arc4 2176 1 ieee80211_crypt_wep 5376 1 ieee80211_crypt 7684 2 ieee80211,ieee80211_crypt_wep 8139too 30336 0 mii 5504 1 8139too ext3 121576 1 jbd 90392 1 ext3 ---------------------------------------------------------------------- tiwai - 11-23-04 16:20 ---------------------------------------------------------------------- It's likely a mixer issue. Could you attach /etc/asound.state? ---------------------------------------------------------------------- bji - 11-24-04 12:33 ---------------------------------------------------------------------- OK, I attached /etc/asound.state. Thank you very much for looking into this problem. ---------------------------------------------------------------------- tiwai - 11-24-04 12:40 ---------------------------------------------------------------------- Please, don't mix up bugs on different systems. Rather create a new bug report for a different board. We can mark them as duplicated once after we find they are really identical. (Both of you have different AC97 codec chips, so the culprit could be also different in a high probability...) ---------------------------------------------------------------------- IceRAM - 11-24-04 13:26 ---------------------------------------------------------------------- Sorry, didn't know that. I was too happy (sort of) because somebody else had the same problem, under the same conditions. That's why I reported here. (I tried cleaning up a bit the Bug report page, but I couldn't remove my attachments). New bug @ https://bugtrack.alsa-project.org/alsa-bug/view.php?id=674 ---------------------------------------------------------------------- tiwai - 11-24-04 14:57 ---------------------------------------------------------------------- Thanks. The problem in this bug seems that some missing codec setup for STAC9752. Needs a more deeper look at the datasheet. ---------------------------------------------------------------------- bji - 11-25-04 07:07 ---------------------------------------------------------------------- Is there something I can do to help? Thanks! ---------------------------------------------------------------------- bji - 11-28-04 04:24 ---------------------------------------------------------------------- Hi there, is there anything that I can to do help diagnose and fix this problem? Let me know if there is. I think I'll start by trying older ALSA versions; like I said in my original report, my Debain Sarge install had ALSA working with this laptop and maybe it was using an older version of ALSA. Thank you! ---------------------------------------------------------------------- bji - 11-28-04 06:04 ---------------------------------------------------------------------- I could not get older versions of ALSA drivers to compile with kernel 2.6.9. The oldest that I successfully got to compile was 1.0.4. It did not fix the problem, nor did 1.0.5. Please let me know if there is something else I should try to diagnose this problem. Thanks! ---------------------------------------------------------------------- tiwai - 11-29-04 17:19 ---------------------------------------------------------------------- Could you try the patch stac9752.diff and change values in "Headphone Pin" and "Line-Out Pin" controls? ---------------------------------------------------------------------- bji - 11-30-04 08:56 ---------------------------------------------------------------------- Unfortunately, the patch did not fix the problem. I applied the patch by running the following commands: cd ~/alsa-driver-1.0.7/alsa-kernel patch -p1 < ~/stac9752a.diff cd ~/alsa-driver-1.0.7 make make install This patched, built and installed new snd-ac97-codec.ko and snd-ak4531-codec.ko modiles. However, when I modprobe -r the old versions and modprobe the new versions, I still received no sound from the built-in speaker or the headphone jack. I also ran alsamixer and played with the settings there, especially the headphone and the line out settings. No changes to these values had any effect. Is there something else I can try :( Thank you for taking the time to try to solve this problem, I really do appreciate it! ---------------------------------------------------------------------- tiwai - 11-30-04 21:02 ---------------------------------------------------------------------- One thing you can check is to set the capture source as 'Mix', and record the sound during playback PCM at the same time. In this way, at least you can see whether the PCM is processed correctly in the AC97 codec (e.g. you can see waves in a sound editor). If the signal is processed properly in the chip, it's a problem of some missing configuration for the HP or Line-Out jacks. ---------------------------------------------------------------------- bji - 12-02-04 06:37 ---------------------------------------------------------------------- I apologize, but I am not very familiar with recording sound under Linux. I am running Fedora Core 3 without Gnome or KDE, and I don't know of any sound recorder that I can use. Can you please give some hints about what I need to do to record sound from the PCM during playback at the same time? Can I do this using a command line tool? I tried using arecord while playing a song using xmms but the resulting file did not show any waves in the graphical xmms display when I played it. I also tried using arecord while playing a .wav file repeatedly using aplay, but the resulting file also did not show any waves in the graphical xmms display when I played it. ---------------------------------------------------------------------- tiwai - 12-02-04 19:20 ---------------------------------------------------------------------- Don't forget to choose 'Mix' as the capture source, and raise 'Capture Volume', turn on 'Capture Switch', too. ---------------------------------------------------------------------- jnm11 - 12-06-04 19:47 ---------------------------------------------------------------------- I have the same intel system and run Fedora core. It seems you must set the "external amplifier" to mute in in the mixer control and then it works. ---------------------------------------------------------------------- bji - 12-09-04 07:06 ---------------------------------------------------------------------- Thank you for the suggestion, unfortunately muting "external amplifier" via alsamixer does not fix the problem. I apologize but I still don't know how to run the record test that you (tiwai) are suggesting. I don't know what program to run to do the audio recording. Can you please suggest a program. Thank you! ---------------------------------------------------------------------- bji - 03-07-05 02:22 ---------------------------------------------------------------------- OK, here's another data point. I recently got a Panasonic Y2 in addition to the Panasonic T2 that I was using when reporting this bug. As far as I know, the hardware related to sound in these two laptops is essentially the same. I discovered that I could get sound to work with the Panasonic Y2 if I did the following: * Booted to Windows XP * Turned the Windows XP volume control to its highest setting * Muted sound in Windows XP (which is how I usually keep sound in Windows XP) Now if I boot Linux with ALSA 1.0.6 (the stock alsa with Fedora Core 3), I can adjust the sound volumes using alsamixer, and everything works. I can play musing using xmms with either the ALSA or OSS plugins, and this also works (although the volume slider in xmms does not work, not sure why, I have to use alsamixer or aumix to adjust sound volume). Also, the speakers work. Thus I am convinced that the problem is that the ALSA driver for this hardware is for some reason not able to adjust the volume beyond some maximum value which was set by the BIOS, as remembered by the most recent Windows XP setting. Does this help at all? Thanks!
