ALSA troubles

hi,

i have problems with alsa.

at the beginning i thought it was a problem with mm-kernel.
the systems hangs on startup but only with kernel 2.6.8-rc4-mm1 & 2.6.8-gentoo-r3
both kernels hang on the same place, before alsa detection.

i have kernel 2.4.26-gentoo-r9 too and it detects alsa and starts normal.

First, a few questions. What driver are you using, and is it a module or binary?

hi,

i use (only the sound related stuff)

Are those listed with the 2.4 kernel, or the 2.6 kernel?

I doubt your kernel hangs because soundcore is compiled directly into the kernel, because I have almost *everything* compiled into my kernel, nad I have no problems.

I'm honestly not sure what else to ask, as I've never had your problem before. About the only other thing I could recommend would be running a "make mrproper" in your 2.6 kernel tree, and try rebuilding it (that wipes out everything, including the .config file, so you could back that up if you needed. It ensures a clean build.)

Make sure you emerged alsa-utils, alsa-lib, but not alsa-driver.

hi,

i emerged alsa-utils, alsa-lib and alsa-driver

because i need alsa-driver for my 2.4 kernel, i think.

What is your /usr/src/linux symlink pointing to? Because if it points to your 2.6 kernel, that could affect things.

hi MighMoS,

/usr/src/linux symlink is pointing to 2.6.8-gentoo-r3!

I think you cannot use alsa in a 2.6 kernel if you have alsa-driver emerged. So try to unmerge it, make modules_install and reboot with your 2.6 kernel.

Alsa is integrated into the 2.6 kernel series, so you must not install alsa-driver when you want to use one of these kernels. I understand that you need it with your 2.4 kernel, but I can't figure a way to have both kernels working. I guess you have to make a choice now...

Oumpah-pah: From what I've gathered, alsa-driver installs similarly as nvidia-kernel does. If the /usr/src/linux sym link points to a 2.4 kernel at the time of install, then it should certainly be ok (I think).

Potatoface, when using the 2.6.x kernels, it is not nessisary to install alsa-driver. Instead, under device drivers--> sound, enable alsa, and the appropriate driver for you card there.

thank you guys,

i have unmerged the 2.4 kernel and when i boot now my 2.6 kernel it starts up without any problem.

the only thing is that everytime i reboot

the master channel is unmuted and set to 100 but

the pcm channel is muted and set to 0.

i must use alsamixer to unmute it and then sound works.

does anyone know how to solve this?
