Re: Trident problems.

[David Parker]

Hi,

A long time ago (many months... sorry I don't know exactly when), my Trident
card stopped working with ALSA on a Debian unstable box. It still works with
the kernel OSS module, but ALSA has problems with the AC'97 codec. Here's what
I tried and the resulting log messages/output:

hypnotic:/home/dap# modprobe snd-trident
ALSA ../../alsa-kernel/pci/trident/trident_main.c:3394: AC'97 codec ready error
Trident 4DWave PCI soundcard not found or device busy
devfs_register(unknown): could not append to parent, err: -17
ALSA ../../alsa-kernel/pci/ac97/ac97_codec.c:2096: AC'97 0:0 does not respond - RESET

hypnotic:/home/dap# modprobe trident

I saw someone else had this same problem on the alsa-devel list a while ago
(http://www.mail-archive.com/alsa-devel@lists.sourceforge.net/msg06500.html)
but it doesn't look like it was ever resolved. Is there something I need to
tweak, or is this a valid bug? If it would help to test specific old versions
of ALSA I could do that too.

Thanks,
David

i have exactly the same problem. the weird thing is when it happened
(many months ago) i tried to go back to the previous working version
and it still didn't work. my theory is that the ac'97 codec got into a
funky state and it's not being reset. unfortunately i don't know what
to do either.

Things have been quiet on this thread... does anyone have any ideas, or any
knowledge of whether or not the ac'97 codec can even get into such a weird
persistent state? Is it something that can be ignored, since somehow the 2.4
kernel OSS module still works? Any help or ideas for me to google on would be
great.

well, i had the card working yesterday but it got noisier over time
and then today after i tried to remove the modules and then reinsert
them i couldn't do it anymore. i wasn;t able to get the oss modules
working (it's been many years since i used oss) so maybe the card is
at fault.

Strange, did you do anything special to get ALSA working with the trident
again or did it just happen to work on the first try?

just the usual: did a cvs update, tried to insert the modules and by
some miracle it worked. same modules don't work today...

CS46xx, TB Santa Cruz, 4+ channel output?

[Joe]

Hi, I've posted on the Alsa-User list, and get absolutely no reply, so I
thought I'd try my luck here.

I've given the same spiel to several forums and lists, so rather than go
over it again, I'm going to post a link to a few of my forum topics, to
see if I can get any help with this.  The problem is I am trying to find
a way to mirror the output on one device (CS46xx) to one or two other
devices ("CS46xx - Rear", and "CS46xx - Center LFE"), and I'm getting no
where.  The alsa-project "Wiki" says that surround output has been
"verified working" with the latest version of alsa, so my question is,
what is required to get that sound mirrored?  Using "surround40" and
"surround51", I get an error, so I don't think that works, yet each
individual output device works, and I get sound on the correct speakers
when I change the output device.

http://forums.gentoo.org/viewtopic.php?p=512760#512760
http://forums.gentoo.org/viewtopic.php?t=76654

Can anyone tell me what I need to do in order to get simultaneous output
on all channels for this particular sound card?

Pertinent info:

$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 0.9.6.
Compiled on Aug 18 2003 for kernel 2.4.20-gentoo-r6 with versioned
symbols.

$ cat /proc/asound/pcm
00-00: CS46xx : CS46xx : playback 31 : capture 1
00-01: CS46xx - Rear : CS46xx - Rear : playback 31
00-02: CS46xx - IEC958 : CS46xx - IEC958 : playback 1
00-03: CS46xx - Center LFE : CS46xx - Center LFE : playback 31

Any other information you need, just ask.

Thanks a lot,

could you please try the attached patch?
if it still doesn't solve the problem, try to increase the length of
timeout in snd_trident_4d_dx_init(), e.g. 

	end_time = jiffies + HZ * 2;

it will wait for 2 seconds.
try this with and without the patch.

if the same problem happens, try to commend out the line
"return -EIO;" in the same function, so that the probing proceeds even
if the check fails.  let's see whether the further ac97 probing
works.

if still fails...  remove the warm reset part.

Sorry for the slow reply... I tried the patch and it didn't work so I also
tried combining the above fixes with and without the patch. Still no luck :(
Would it be helpful to put debug messages on each line and pasting that, or
should I try something else?

Thanks,
David

didn't it work even if you ignore the error as mentioned above?
then it means that ac97 is really not ready for use.
i'm afraid something is broken.
