[gentoo-user] Can't get ALSA OSS Emulation to work

[gentoo-user] Can't get ALSA OSS Emulation to work

[Raphael Melo de Oliveira Bastos Sales]

Hi everyone,

   After some days googling for it, I give up  now and come here for
help. I have Alsa installed in kernel, and it works fine for programs
that are compatible with. But programs that need OSS don't get any
sound. I have the following lines in the alsa config files:

    /etc/modules.d/alsa:
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

alias snd-card-0 snd-via82xx
alias sound-slot-0 snd-via82xx

     When I run the alsasound init script it says:
 * Loading ALSA modules ...
 * Loading: snd-card-0 ...                                              [ ok ] 
 * Loading: snd-seq-oss ...                                            [ ok ]
 * Loading: snd-pcm-oss ...                                           [ ok ]
 * Restoring Mixer Levels ...                                          [ ok ]

# cat /proc/modules | grep oss
snd_pcm_oss 52576 0 - Live 0xe258b000
snd_mixer_oss 19648 1 snd_pcm_oss, Live 0xe1111000
snd_seq_oss 37568 0 - Live 0xe2512000
snd_seq_midi_event 7168 1 snd_seq_oss, Live 0xe0da9000
snd_seq 55056 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event, Live 0xe086d000
snd_pcm 93448 3 snd_pcm_oss,snd_via82xx,snd_ac97_codec, Live 0xe0db0000
snd_seq_device 8972 4 snd_seq_dummy,snd_seq_oss,snd_seq,snd_rawmidi,
Live 0xe084a000
snd 57412 13 snd_pcm_oss,snd_mixer_oss,snd_seq_dummy,snd_seq_oss,snd_seq,snd_via82xx,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device,
Live 0xe0d79000

So it seems that the modules are loaded correctly. But every program
that tries to pipe to /dev/dsp gets broken pipe (i.e. Quake and Enemy
Territory).

If anybody can tell me what could be wrong, please let me know. If
there is a config file that is important and that I didn't send it
here, tell me and I'll send them.

Thanks for the attention,

Raphael

Hi Raphael,
   Change the items in /etc/modules.d/alsa as proper for your via
sound chip. Run modules-update after making changes. You seem to be
missing a number of the alias statements. The following file works for
a 2 sound card system.

Hope this helps,
Mark

[Nick Rout]

The setup on gentoo changed sometime around alsa-lib 1.09.

Leave ALL of the oss stuff out of the module config files (running
alsaconfig will set it up correctly)

Then set ENABLE_OSS_EMUL="yes" in /etc/conf.d/alsasound

my /etc/modules.d/alsa now reads:

nick@sf /etc/conf.d $ cat /etc/modules.d/alsa
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.9a ---
options snd  device_mode=0666
alias snd-card-0 snd-via82xx
alias sound-slot-0 snd-via82xx
# --- END: Generated by ALSACONF, do not edit. ---

/etc/conf.d/alsasound now reads:

# ENABLE_OSS_EMUL:
# Do you want to enable in-kernel oss emulation?
# no - Do not load oss emul drivers
# yes - Load oss emul drivers if they're found

ENABLE_OSS_EMUL="yes"

# RESTORE_ON_START:
# Do you want to restore your mixer settings?  If not, your cards will be
# muted.
# no - Do not restore state
# yes - Restore state

RESTORE_ON_START="yes"

# SAVE_ON_STOP:
# Do you want to save changes made to your mixer volumes when alsasound
# stops?
# no - Do not save state
# yes - Save state

SAVE_ON_STOP="yes"

Re: [gentoo-user] Can't get ALSA OSS Emulation to work

[Mark Knecht]

Nick,
   Interesting. I have something like 8 Gentoo machines I run Alsa on.
All of them use OSS emulation at least partially. I do not remember
any messages or guidance to do what you're say, but indeed, it makes
sense, sort of... Unfortunately, it seems that emerge didn't tell me
to do this or, if it did, then the messages were lost in an endless
stream of compile text while doing an emerge world.

   I suppose I really don't like this way of doing it since it now
makes Alsa set up for Gentoo different from what is specified on the
Alsa pages. It also seems that the /etc/conf.d/alsasound page may not
give me as much control in my systems where I'm using multiple sound
cards. I'll have to review that more carefully.

   Humm... Are there any new online instructions that specify all these changes?

Thanks,
Mark

[Raphael Melo de Oliveira Bastos Sales]

Thanks for the attention. I did both ways and I still get error messages like;

Enemy Territory:
/dev/dsp: Input/output error
Could not mmap /dev/dsp

and

Quake 3:
/dev/dsp: Broken pipe
Could not toggle.

cat /dev/urandom > /dev/dsp  also does nothing

Maybe some clues, I don't know:

# cat /proc/asound/cards

While I'm at it, how does the -D option of alsamixer works? When I put

Sorry for sending such a big message, but this problem is really annoying...

Thanks again for the attention,

I didn't find any, i figured it out for myself.

I posted to this list, then found the solution then posted a SOLVED
message almost staright away, a week or 2 back.

Re: [gentoo-user] Can't get ALSA OSS Emulation to work

[Nick Rout]

I can only suggest you look carefully at /dev/dsp - it should i think be
a link to /dev/sound/dsp.

Then look at the permissions on /dev/sound/dsp - they should be:

crw-rw----  1 root audio 14, 3 Jan  1  1970 /dev/sound/dsp

and the user trying to run the errant program should be in the audio
group. (and re-logged in if you add them as a result of this message, ie
adding a user to a group does not take effect until they log in again.
Unfortunately this can mean logging oput of X and back in again)

You can check if user is in the audio group with:

id user

I just thought of it now. Could this be a udev related bug? I'm using
udev and may be I misconfigured something.

Nick,
   Sorry for not seeing the post or the work you were doing in this
area. I haven't been reading this list in depth lately.

   As I say, I think the capabilities provided here by the Gentoo devs
look good, but I get the feeling there maybe wasn't so much thought
given to multiple sound card systems. For instance, if I have an
expensive sound card in a system which also has an on-board sound
chip, then maybe I want Alsa support for both devices, but OSS support
only for the second card. Game audio, etc., goes there while recording
studio audio goes through the high-end card using Jack. This allows me
to run Jack through the first card while I run OSS through the second.
The first card goes to external D/A & A/D converters. The OSS audio
goes out of the machine as analog and into an external A/D to get
resynced with Jack. How do I do this? (I.e. - I can do it easily with
the sort of configuration I presented earlier.)

Thanks,
Mark

possibly, take a look at those files and permissions I suggested.

if they are wrong, then indeed it may be udev at fault.

Re: [gentoo-user] Can't get ALSA OSS Emulation to work

[Raphael Melo de Oliveira Bastos Sales]

I feel really stupid. It wasn't the permission, but to get both quake
and enemy territory to play , they have to be given direct access to
the sound hardware. To do that, you must go to
/proc/asound/cardX/pcm0p/ and add the following line to the oss file
in this directory. Something like this:
echo "q3demo.x86 0 0 direct" >> /proc/asound/card0/pcm0p/oss

I was putting just q3demo, which is actually just a script to call the
game, not the program that would use the sound. And that's why it
didn't work. Thanks for the help. I'll try to have more attention to
this type of details in the future.

Thanks again Nick and Mark ;)

Shouldn't the ebuild when it installs make those changes automaticly? 
When I tried out q3demo last year the sound worked fine same with
Enemy Territory.

Hi Chris

Unfortunately, it didn't. And I also have to do it everytime it
restarts. I'm thinking about doing a init script to do it for me...
