OSS works randomly with oss_hdaudio0 Creative Labs XFi XTrem

[microry]

If I run : ossplay a_sound.wav many times, it produces sound one time in three/four (randomly).
The same with osstest

In dmesg there is some errors but rarely (not for every ossplay or osstest execution) :

I'm lost and I don't want to go back to ALSA...

Why do you need OSS4?

[microry]

Because the sound is better than ALSA

[cesium]

microry: What happens if you disable vmix? i.e. "ossmix vmix0-enable OFF"?

[microry]

it works every time !

[microry]

I hope I won't have to use pulse audio to replace vmix...

[cesium]

Now try this:
A) Edit /usr/lib/oss/conf/osscore.conf and add the line "vmix_no_autoattach=1".
B) Restart OSS with "sudo soundoff && sudo soundon"
C) Run "sudo vmixctl attach -M /dev/dsp /dev/dsp_in"

And test again. Does this issue still appear?

[microry]

Code: Select all

# vmixctl attach -M /dev/dsp /dev/dsp_in
/dev/dsp_in: Device or resource busy


and nothing in dmesg

[cesium]

oops, no second argument in this case, so it's just "vmixctl attach -M /dev/dsp".

[microry]

Code: Select all

# vmixctl attach -M /dev/dsp
Virtual mixer attached to device.


But the problem persists... (osstest works 100%, osstest -V ~30%)

[Indeec]

Same problem with the same card. Is there a way to fix it? I am currently using oss 4.2 2007 from source code.

[cesium]

Well, I guess we'll have to experiment. What happens if you disable vmix (as explained above) and reattach it using both '-M' and '-r' flags?

[Indeec]

Nothing changes. Still the same problem - sometimes all works perfectly, sometimes no sound at all. Even without vmix. Hope there is a way to fix it, i realy don't want to use alsa again.
p.s. sorry for my bad english, it's not my native language

[cesium]

Oh, so your problem is different from the other user... Can you paste here output of 'ossinfo -v3', 'ossmix -a' and 'lspci -vnn'?

[Indeec]
