upgraded kernel to 2.6.8.1 now no sound
I upgraded the kernel from 2.6.3.7 to 2.6.8.1 and now the sound doesn't work. Even if I boot back into 2.6.3.7 it does not work.
Sound did work before I updated. btw, i compiled from complete source, not patch. lspci returns 00:1f.5 Multimedia audio controller: Intel Corp. 82801DB AC'97 Audio Controller (rev 01) Exactly what options should I have set when configuring the kernel. I used xconfig. I tried selecting intel for the sound card but no luck. ALSA and OSS are selected. It appears that there are no mixers installed anymore. ?? When trying to set the sound settings in control center I get : device /dev/dsp can't be opened (No such file or directory) I verified that there is indeed no directory with that name but there is /dev/snd and /dev/sound did I do something wrong when configuring the kernel or is there something else that I should install. OS: Mandrake 10.0 Computer: Dell 600m laptop I think that everything else is working ok. |
seems strange.
try this command as root: /dev/MAKEDEV audio that will make the file /dev/dsp if your using alsa you might need to add the OSS PCM API and OSS Mixer API options |
same here
I have the same Problem, I have not changed anything. I just upgraded? I have not done any extensive looking, just a quick search. I did not look at any changes or anything due to the dredful thing called limited time. A quick make oldconfig, make menuconfig, changed PentiumM and added cpu freq scaling stuff (Inspiron 8200). And that was that, cp, blah and etc (I have done this a couple times). I do not know what the problem is. Any advice, help, aid etc, thank you in advance.

I had this problem recently on my 500m. Are you using hotplug and alsa? the problem is most likely that the old sound modules are being loaded first, before the alsa ones and this screws things up. Well, that's what happened with my debian laptop.
Try editing the blacklist in /etc/hotplug/blacklist and add the OSS modules to it. mine contains the following: ====== #try to get sounds working again audio snd-usb-audio i810_audio snd-intel8x0m #i810_audio is OSS module and snd_intel8x0m is modem ====== if this doesn't fix the problem, hopefully it'll put you on the right track... |
I am using alsa... so I tried adding a a couple of these to the /etc/hotplug/blacklist, then did (each time the <file> was editied
/etc/init.d/hotplug restart ; /etc/init.d/alsasound restart Alright, lsmod: Code:

/dev/dsp is the device for the OSS which is now deprecated. So we are supposed to stop using it.
But there is some problems with this card with ALSA. I still have to updated to a newer version of the kernel, but I found out that if you modprobe snd_intel8x0 rmmod snd_intel8x0 modprobe i810_audio chmod 777 /dev/dsp chmod 777 /dev/mixer gives me sound in a version that didn't give sound because of a buggy snd_intel8x0 module. There was a warning on the alsa project site. The downside is that it wasn't made to work this way and therefor probably makes the system a bit unstable. Because as long as we inicialize the ALSA submodules the OSS emulation is there. Don't forget that in the new 2.6.x kernel if you are trying to use OSS modules. |
I had a somewhat similar problem with HP d530 sff, programs were complaining about
/dev/dsp. I simply repaced ALSA by OSS and it "just worked" for my big surprise. This is probably an ALSA bug related with intel8x0. Ott |
ALSA works with a little pushing... also need to make sure all your apps are using ALSA. and/or build OSS compatibility mode into the kernel along with ALSA.
Also, you can try just using a daemon like esound or something; I do that, my env is gnome with enlightenment as wm, and I just use the esound daemon and get all apps to play through that last but not least, check your mixer settings, the upgrade might have reset them all to zero (use alsamixer). have fun! hope this helps! |
