Hello

I don't know if this is the right place but to post about it but I found that using a menuconfig kernel config would render my system incapable of any sound playback. I realized that this was due to the fact that the sg support was not turned on in the block layer section of the kernel. I was wondering why this is needed as I thought this was a scsi drive mount/handling prerequisite? Anyhow I didn't have any sound because of it. Now I do tough. Perhaps the pulseaudio wiki needs a notice about it.

Cheers
R

Not quite sure I understand that fully, you left out some detail that would be useful, but:

I think you're saying you rebuilt a working kernel via make menuconfig and it wiped out your sound drivers?

That shouldn't happen if you update the kernel correctly.

Check out https://wiki.gentoo.org/wiki/Kernel/Upgrade#make_oldconfig and see if you missed a step.

So I built my own kernel config and made sure all the kernel options in the pulse audio wiki was set correctly. I removed the scsi drive support and as a result sound stopped working. As I wrote earlier, but yes I did not use the supplied or Gentoo endorsed standard kernels. This is why I posted here in chat and not as an issue. I thought it might be good to know that setting the kernel options as specified in he wiki for having working sound and deactivating a hard disk drive option results in the sound not working...

rictjo,

Removing sg support will remove raw access to your optical drives, so no CDDA support, no DVD playback, no optical disk writing.
There are a few rarer things that us it too.

It has no effect on audio.
