Wow, I cannot believe that it was that easy (after all I tried). Thank you 
very much.

Now there is just a minor problem that my MIDI device is not detected 
correctly, but that's not that crucial.

I'm not much help with MIDI. I don't like Linux MIDI so I still do all
of that in Windows. Maybe one day....

I accept. Next time I'm in Germany or you're in the SF Bay Area we
must get together.

Re: [gentoo-user] ALSA problems after UDEV-103 upgrade [SOLVED]

[Arend von der Lieth]

Now that I have marked that thread as "SOLVED" I feel obliged to give a short 
update (what really solved the problem):

deleting /etc/asound.state unfortunately did not solve the problem, it just 
helped suppressing the warning message. I did not really notice as I had KDE 
use autodetect for sound, so it used OSS and not ALSA. That was not too bad, 
but I did not have any sound in my favorite game (which uses alsa) and 
therefore had to look a bit deeper:

it seemed that ALSA had a problem with the missing /dev/snd directory ("cannot 
find soundcard 0") though it should have been created during boot according 
to /etc/udev/rules.d/50-udev.rules. 

So, I messed around a bit with the alsasound start script 
(/etc/init.d/alsasound) and created /dev/snd as symbolic link inside the 
start() function. After that I had some problems in shutting down, so I 
added "rm -f /dev/snd" inside the stop() function and everything works well 
(eventually).

But I have to admit that I do not feel very comfortable with this 
modification. Does anyone have a better idea??

Kindest regards and thanks in advance,
Arend
