  Hi Clemens,

Thanks a lot. Does it concern only /usr/share/alsa/alsa.conf file, or 
the files configured in the config hooks too (/etc/asound.conf, 
/alsa.conf.d/, ~/.asoundrc)? Based on your answer I assume not :-)

Could I setup ALSA_CONFIG_PATH=$USER/.my_global_alsa.conf as a symlink 
to /usr/share/alsa/alsa.conf and touch this symlink only?

I very much appreciate this great help.

Pavel.
