Re: cmpci sound chip lockup

[Dmitry Volkoff]

Hello,

This is known issue. cmpci driver included in the kernel is way too old.
I'm using newer driver (revision 4.14) and it works just fine. It was 
announced on lkml long time ago. Last time I checked there was even newer
driver - 5.64. The one in the kernel has version 2.41. Is it possible to 
include the new driver? 

This is the homepage: http://members.home.net/puresoft/cmedia.html

Can you try this patch? some parts are just some cleanups, but there are
two bugs fixed, this was just a quick look, maybe there are other bugs.

Nope. I also get this with xmms directly to /dev/dsp.

I can also report that I'm having the same problem running kernel
2.4.[3-4{ac1-9}] with a C-Media using ESD. So the problem appears when I
tried to run XMMS with ESD, the sound have an annoying "ss ss ss
..." while I play mp3's. The frecuency of the "ss ss ss ..." is symetrical
(1/4 of a second I say).
The problem appears to have a direct asociation with esound cause it only
happens with the use of XMMS over ESD. No problems reported during
execution of mpg123 wich not use esound.

Your xmms uses esd[1]?

Friends of mine report problems with esd and 2.4.x. Tested on
SB-Live! and es1371.

Re: cmpci sound chip lockup

Just a "me, too" here.  I see this when using the in-kernel driver.  I'm
now using... 4.12, I think.  At any rate, the error doesn't occur, or at
least occurs to rarely as to escape notice, with this driver.  Might I
suggest the kernel's version be upgraded?  The updated driver was posted
here on lkml some time ago.

Too bad my mailreader doesn't quote that thing .. oh well, lets

I'm seeing a similar thing on 2.4.4-pre[23], but in a far less
serious way. Using xmms the music stops after anything between
a few seconds and a minute, I suspect a race condition somewhere.

Using mpg123 everything works fine...

1) While playing mp3's on mpg123 it'll lock up for 3/4 seconds, and XMMS just stops all together
