Try re/installing alsa, alsa-utils
Did you reinstall the two packages?
Yes,it did not seem to help.I am running from a live dvd right now.It correctly identifies the ALC887 hardware
in phonon and the files in /usr/share/alsa that were missing are now there.
file:///usr/share/alsa/alsa-utils
file:///usr/share/alsa/alsa.conf
file:///usr/share/alsa/bluetooth.conf
file:///usr/share/alsa/smixer.conf
file:///usr/share/alsa/sndo-mixer.alisp
Kmix had the sound slider for cd only and it was muted.I added more controls such as PCM2, Line,and Igain but still no
sound.Using clementine to test.
