I didn't (maybe still don't) have ALSA loopback so I could record streaming, so I upgraded ALSA following these instructions:
http://alsa.opensrc.org/index.php/Ja...loop_if_needed
The only part I didn't follow verbatim was the final step:
Quote:
Allrighty, time to load it. But before that, shut down all audio apps (including firefox). Once done, do this:
Code:
sudo alsa force-unload
sudo modprobe snd-whatever-module-you-need
sudo modprobe snd-aloop

I was unsure about "snd-whatever-module-you-need" so I decided to reboot.
When KDE was just about to kick in, I saw a lot of new text I had never seen before scroll past very, very fast. Then it stopped and I could see it had something to with ALSA, but I couldn't really read anything. KDE started and... now I have no sound.
I checked kmixer, it looks normal. It doesn't seem to be mute.
I ran alsamixer in the command line, it doesn't seem to be mute either.
I ran Kcontrol and checked the audio section, couldn't figure anything out.
Here is the output of lsmod BEFORE the upgrade:

Looks like I have lost snd_seq_dummy, snd_seq_midi and snd_rawmidi. I don't need midi, so I just tried to load snd_seq_dummy with modprobe. The module is not found.
I reboot another two times hoping to be able to read something in that new boot sequence text, but I don't see it anymore. It's gone.
I don't know what else to do. Any ideas?
All mute after upgrading ALSA
