OSS issues after 2.6.10 compile

KingOfDreams · 03-02-2005, 01:57 PM

I compiled ALSA as a module, included OSS emulation. I ran alsaconf, the AC97 onboard is found, alsamixer - ok. All the snd modules are loaded. The problem is that I have
/dev/dsp
missing, which means that I cant use OSS emulation. I think the compilation wiped out my /dev/dsp*.
Which options should I choose in the ALSA configuration section in the kernel so I dont get /dev/dsp* missing and have OSS emulation working?
And what generates the /dev/dsp* devices?

Thanks!

I have fresh 10.1 install

Is your /etc/modules.conf correctly set up? (See http://www.alsa-project.org documenation on your soundcard on how to do this)

Or, you can just run these lines, then add them to /etc/rc.d/rc.local:

Code:

modprobe snd_pcm_oss
modprobe snd_mixer_oss

well, after typing lsmod i see that all necessary modules are loaded, i recompiled the kernel and put the ALSA in, not as module. But still i get /dev/dsp* missing which are used by OSS. I dont know what to do to have /dev/dsp*.

Including snd-pcm-oss, snd-mixer-oss and snd-seq-oss? Without these modules loaded, udev does not create device nodes for the OSS emulation components.

I ran alsaconfig, alsamixer, alsactl store. After reboot:
lsmod

Code:

Module                  Size  Used by
snd_seq_oss            34688  0
snd_seq_midi_event      6400  1 snd_seq_oss
snd_seq                51984  4 snd_seq_oss,snd_seq_midi_event

snd_page_alloc          7940  2 snd_intel8x0,snd_pcm

But typing
alsactl restore

Code:

alsactl: load_state:1267: No soundcards found...

This is what I get before and after starting the X server.
/dev/dsp* and /dev/mixer* are still missing.

And this is my modprobe.conf

Code:

# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 1.0.8 ---
alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-intel8x0
# --- END: Generated by ALSACONF, do not edit. ---

I would check /etc/rc.d/rc.alsa that is responsible for sound stuff settings.
If hotplug/udev do not create the necessary device nodes try creating them manually editing your /etc/rc.d/rc.local.
Make sure major/minor numbers of those devices are created according to lanana assignements.
Hope this helps

Compile ALSA as built-in, with OSS emulation of course

C-
