[SOLVED] No Sound in CRUX???

[jayd512]

I got Flash going in CRUX, so at least I can watch such things as Youtube. But I can't hear a thing! I'm not really sure what I may have missed hear How does one get sound in CRUX? (

[Dapper Dan]

Hi Jay, can you get sound when playing sound files or on the net? If not, did you run alsaconf yet? If so, and it doesn't find your sound card, you likely will have to re compile to include the driver(s). If alsaconf does find it, configure accordingly. Afterwards, run alsamixer and turn volume up. When everything is as you want it, be sure to run:

/usr/sbin/alsactl store

to set it. Got youtube video with sound here so I know it can be done.

Let me know how it goes...

Hi, Dapper!

I get no sound for anything at all. My sound card shows up in lspci as

00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 Audio Controller (rev 11)

But when I run alsaconfig it tells me that there are 'No Legacy Drivers Available.' I re-compiled the kernel, so I'm pretty sure that the drivers are installed. I'm not afraid to go through another compile if I need to, but would like to avoid it. Anything I might be missing here?

Hiya Jay and Dan,
I had a similar problem with

00:1f.5 Multimedia audio controller: Intel Corporation 82801AA AC'97 Audio Controller (rev 02)

On Gentoo, all I could come up was using rmmod to remove all of the snd_ modules one by one, which sucks because some modules wont shut down until another one shutdowns first?! Then using modprobe snd_intel8x0 to restart them all. But in the end I got it to work this way.

[jayd512]

Hey there, Mike!

Thanks for that! Now I hate to sound like a noob, or worse yet like somebody who hasn't done their homework, but I've never had to use rmmod before. Any pointers on what I might be looking for?

I'm using Intel sound as well, ( Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02). Here's my lsmod as a reference but really not sure if it applies to your device and situation though as there is a difference in model:

Check and see if the module(s) are getting loaded by /etc/modprobe.conf. In mine it loads snd-hda-intel. You could try:

/sbin/modprobe snd-hda-intel

And see if that does it. If snd-hda-intel is not in /lib/modules/2.6.*.*/kernel/sound/pci/hda then you may need to recompile and include it. Luckily as you know, kernel compile in Crux is a piece of cake.

EDIT: Through the recompile process, I eliminated all but the hardware drivers that applied to this Crux box as there is no need for them making for a leaner cleaner kernel.

[jayd512]

/sbin/modprobe snd-hda-intel

gave me

FATAL: Module snd_hda_intel not found.

So I guess a compile is in order... I'll give an update as it goes forward!

[Dapper Dan]

Research it first though and I'll do it to. As MikeTbob says, it might very well use intel8x0 instead.

[MikeTbob]

I'd try Dans suggestion first Jay, If that fails you can use rmmod (remove module) fairly easy.
rmmod modulename
In the example provided by Dan, to remove the snd module, you have to notice it's in use by other modules, which need to be unloaded before you can unload snd.
I just noticed another thing that might prove useful to someone.
Using Fedora 9, I had no sound until I tried a tiny program called alsaunmute from the command line.

[Dapper Dan]

A few short Googles leads me to believe MikeTbob is right about the module. I think you need snd-intel8x0 instead of snd_hda_intel but as long as you're recompiling, just include them both!
