/dev/dsp -- how do I set it up? (no sound RTCW issue)


Distro: Debian Sarge.
kernel: uname -r =2.6.8-2-k7
desktop: KDE 3.3.2

symptoms:
1) some sound apps work. I can play an mp3 from my cdrw dev/hdc aka /media/cdrom0 with Noatun, Kabodle, Totem movie player (all by right clicking the .mp3 and selecting the app).

2)
a. some sound apps don't work. XMMS complains:
Couldn't open audio Please check that: Your soundcard is configured properly You have the correct output plugin selected No other program is blocking the soundcard"
b. Rythmbox Music Player also can't play and complains:
1st error box -- "could not pause playback"
2nd error box -- "Device "/dev/dsp" does not exist"

3) Return to Castle Wolfenstein graphics load but not the sound: "Could not open /dev/dsp". I opened a root terminal and browsed to /dev but didn't see 'dsp' anywhere.

4) ps aux output lists several items including aRts which I know is associated to sound:
beebleq 4750 0.3 0.8 21884 8328 ? S 07:48 2:01 /usr/bin/artsd -F 10 -S 4096 -d -m artsmessage -c drkonqi -l 3 -f

Mmmkay. How do I configure my sound properly? It's onboard nforce sound on Abit NF7-S ver.2 (Nforce2 ultra).

MEPIS didn't give me any problems with sound -- anyone know how to parrot on Debian what MEPIS does by default?

you have sound. you just have some settings off in xmms. right click xmms and look over the audio settings in preferences or something like that

There may be a chance that the permissions on /dev/dsp are set too strictly. I've had that problem before but with slackware. If the user is unable to access /dev/dsp, then you will get those kind of errors. Changing the permissions may do the trick.

but Noatun, Kabodle, Totem works, so i don't think it's permissions. also look to make sure that /dev/dsp is your sound card and not /dev/snd or something similar

bosewicht: I think before I start changing settings in there I'd better get more specific feedback. I actually did try switching between Alsa, esound output plugin and OSS, but nothing changed (still get error). I don't think it's XMMS because at least two other apps also don't work.

Maestro485: nothing can be hidden from root and that's how I browsed to see no /dev/dsp. So I don't think it's a permission issue (not permissions with root). I do have these devices(?) under dev/snd:
debian:/dev/snd# ls -la
total 0
drwxr-xr-x 2 root root 160 2006-01-24 21:15 .
drwxr-xr-x 12 root root 3920 2006-01-24 21:16 ..
crw-rw---- 1 root audio 116, 0 2006-01-24 21:15 controlC0
crw-rw---- 1 root audio 116, 24 2006-01-24 21:15 pcmC0D0c
crw-rw---- 1 root audio 116, 16 2006-01-24 21:15 pcmC0D0p
crw-rw---- 1 root audio 116, 25 2006-01-24 21:15 pcmC0D1c
crw-rw---- 1 root audio 116, 18 2006-01-24 21:15 pcmC0D2p
crw-rw---- 1 root audio 116, 33 2006-01-24 21:15 timer

Anyone think this is trying to be /dev/dsp?

funny. you posted in that 4.5 minute interval that I did...

Ok, so /dev/snd IS relevant. Now what do I do with it?

ok, so in xmms change the dev from /dev/dsp to /dev/snd the apps are defaulting to /dev/dsp and there is none, hence the errors. You have sound, it works, those apps are looking at the wrong device.

No. We're getting no joy here. It's more than one solitary application(XMMS). What's the connecting master application that affects XMMS, Rhythmbox, OSS based games like RTCW? Anyone?

this may be a udev thing, so there may be a udev way to fix it, but do you have /dev/dsp0, /dev/dsp1, etc.? if so, did you try linking /dev/dsp to /dev/dsp0:

ln -s /dev/dsp0 /dev/dsp

(do as root, and check permissions are ok)

I think my problem is that Sarge didn't automatically load nforce sound stuff. It loaded intel drivers, which is incorrect.

MY NEW QUESTION: how do I configure my sound card so that I get nvidia drivers instead of intel?

Idea -- gonna disable the onboard sound in BIOS and see if Linux can fix it. BRB.

maybe this has already been addressed but have you checked in `alsamixer`, i know there are many settings available on my nforce2 board..

also did you install the nvidia nforce drivers? IIRC, I leave all sound options blank except for AC97 in the kernel config and then install the nforce drivers, otherwise there were some weird conflicts.. i cant remember though for sure.. havent recompiled in a couple months..

i would check `alsamixer` atleast youll see what card is being detected by alsa..

Anyone having sound problems in Wolfenstein Enemy territory or other games can try the suggestions here. https://help.ubuntu.com/community/EnemyTerritory I am running Debian Etch, not Ubuntu, but the suggestions work for most distros. If not, change the commands a little bit to fit your distro. Let me know if this helps.

you guys are awesome I never actually got it fixed, and I think it was because I hadn't installed the drivers. thx for keeping it alive -- just installed Xandros a few days ago and plan on getting it to work.
