2.6.5-gentoo nosound / 2.6.3-gentoo-r1 works OK

Hi,

I just installed kernel 2.6.5-gentoo and the sound is gone. If I boot with my previuos kernel 2.6.3-gentoo-r1 everything works.

I compiled 2.6.5 using makeoldconfig and it did not ask me anything about sound. I have checked and the sound modules are loaded and everything seems just as in 2.6.3.

where should I start looking for the problem ? are there any 2.6.5 kernel alsa issues ?

thanks in advance.

I had the problem too, but I got sounds back after I did

That means either 2.6.5-gentoo should not be masked as stable or that a newer version of the alsa lib and utils should be marked as stable.

I try to avoid installing masked packages, is there any other workaround ? Thanks

That's a valid point. If the 2.6.5 kernel really needs the newer Alsa files, they should be unmasked for stable users, for consistency's sake if nothing else.

One other thing you could check is that all relevant mixer sliders are up and unmuted using alsamixer, kmix, or whatever. My own sound comes from a crappy VIA 8233 onboard south bridge, and after a kernel upgrade a while back, I discovered that there were four extra mixer sliders called "VIA DXS" which were muted, resulting in no sound and much head scratching. Sliding them up fixed the no sound problem.

Thanks gun26 because your reply guided me in the right direction.

I remembered that my sound also desapeared when I updated kde from 3.2.0 to 3.2.1. I new "button" was in the advanced zone of kmix:

"External amplifier power Off"

and it was enabled. It appeared with the new kmix version and I had to switch it off to turn the amplifier on

Now I had a look at kmix when booting 2.6.5 and the same "button" changes it name to

"External Amplifier"

As you can imagine nor only the name changed but also its meaning. Enabling it restores my sound (and turnes the sound off when booting with 2.6.3)

I do not quite understand why the interface of kmix changes when changing the kernel, but is does.

Thanks for your help.

I have been thinking about it and I was just about to write the same (although it was an asumption) as you did. The mixer gets info about the soundcard through the driver, and if the driver changes (which could happen when switching a 2.6 kernel) the mixer changes the info displayed and controls related to the soundcard.

I my case what happened was that one of the controls changed its meaning (off->on).

Thanks for your explanation.

i noticed that there was a small title-less tab at the top of gnome alsamixer, this led me to conclude that somehting else had stolen the address hw0,0 if i made the card hw1,0 the default it worked, my .asounrc is as follows
