It might be that the formerly saved asound.state brought the
inconsistency.  Try to remove the saved state (either
/var/lib/alsa/asound.state or /etc/asound.state) after unloading the
sound driver modules and reboot/retest.

In anyway, give alsa-info.sh output with the affected machine.
Run the script with --no-upload option, and attach the generated
file.


thanks,
