Description Forgotten User iWJ8PVCHsF 2005-11-01 16:42:44 UTC

It seems, there is some problem in sound subsystem.
Sound in some applications (especially games - for.ex. Tuxracer, TORCS, etc...) does not work. But sound in KDE applications (and KDE system sounds also) works OK.
There is following message on the console after application start (from command line):
SNDCTL_DSP_SETFRAGMENT: Invalid argument
Warning: Couldn't set audio fragment size
Audio write: Invalid argument

May be there is some problem in KDE sound daemon - reconfiguration attempts in the KDE Control Center ends in endless loop (periodicaly sound system restarts).

My sound card: Sound Blaster Live! (CT4832).

Could you give me strace output for one of the problematic application? 'strace -fe trace=ioctl,open <command>'

Comment 3 Forgotten User iWJ8PVCHsF 2005-11-03 23:24:29 UTC

Hi,

I have tested Mplayer now. From my point of view (_I_am_not_ALSA_expert_) there is some bug in the Alsa OSS emulation ??
- Mplayer's sound works OK with the ALSA audio output driver
- Mplayer's sound does not work with the OSS audio output driver

Message on the console after Mplayer (with the OSS ao driver) startup from command line:
...
Checking audio filter chain for 48000Hz/2ch/s16le -> 48000Hz/2ch/s16le...
AF_pre: 48000Hz/2ch/s16le
[AO OSS] audio_setup: driver doesn't support SNDCTL_DSP_GETOSPACE :-(
[AO OSS]
   ***  Your audio driver DOES NOT support select()  ***
 Recompile MPlayer with #undef HAVE_AUDIO_SELECT in config.h !
...

Unfortunately there are many applicatons without native ALSA audio output (e.g. games, which are part of the  SuSE distro (!)) - OSS emulation is needed. Thank you for your help.

Comment 4 Jaroslav Kysela 2005-11-04 08:44:13 UTC

It seems that this problem is only related only to the ca0106 driver - there are strange contrains regarding the buffer sizes. I will try to reproduce the problem here.

But my sound card is old Sound Blaster Live! (Model: "Creative CT4832 SBLive! Value"). No SB Audigy LS or SB Live! 24bit. I think, there is EMU10K1-driver used ??

I found similar problem reported to Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=127766

Any news on bug 131794 ?

Comment 8 Jaroslav Kysela 2005-11-18 10:09:28 UTC

Yes, you're right. The emu10k1 driver is used in your case. Unfortunately, I cannot reproduce the bug here.

Could you get the ALSA driver 1.0.10 from the ALSA's website and enable OSS emulation debugging in alsa-driver/alsa-kernel/core/oss/pcm_oss.c - look for disabled OSS_DEBUG #define?

Also, you have to install kernel-source rpm and follow the instruction for BUILDING ADDITIONAL (EXTERNAL) MODULES in README.SUSE file in /usr/src/linux-*/ directory to prepare kernel for the external driver compilation.

The steps for the driver compilation:

./configure --with-cards=emu10k1
make
cd utils
./insert emu10k1

To restore the original sound settings after tests, edit the /etc/modprobe.d/sound file (uncomment the alias line).

I am sorry for my delayed response....
Now I have installed the alsa emu10k1 driver from 1.0.10 source code, there is the same problem as with driver from SUSE 10.0 binary packages.
But there is now interesting message in the system log (/var/log/messages) from sound subsystem initialization (lines with "unable to register..."). See below. Hopefully it can help you.

WONTFIX is not acceptable for such a fundamental bug.

Comment 13 Egbert König 2006-02-26 20:35:19 UTC

The solution is to disable the open sound system in the kernel. In the SuSE default kernel configuration it is enabled as a loadable module. Remove

CONFIG_SOUND_OSS=m

from your kernel configuration (or use make xconfig or make menuconfig to do this). I have rebuild and installed the kernel. All applications like supertux, VMware etc. which are programmed for OSS are running now with sound.

Hopefully the SuSE team will change this option in their kernel, so that I will not have to rebuild the kernel after each kernel update (and other users too).
