If some application blocks your sound device, you can see that via
 Code: 
lsof | grep snd

http://wiki.ubuntuusers.de/Soundkarten_konfigurieren/HDA?redirect=no hat folgendes geschrieben:: 
Dazu muss die Datei /etc/modprobe.d/alsa-base.conf ... folgende Zeile eingefügt:
 options snd-hda-intel model=3stack
 
 Nach dem Ändern der Datei kann der Rechner neu gestartet werden. ALSA erfährt dann beim Starten, welcher HDA-Typ angesprochen wird.
 After restarting the problem still persisted. Well since then there has been an intervening cold start.
 
 On getting to desktop minimised all windows and ran
 
 Code: 
kanotix@Kanotix:~$ lsof | grep pcm
lsof: WARNING: can't stat() ext2 file system /isofrom
 Output information may be incomplete.
 lsof: WARNING: can't stat() squashfs file system /filesystem.squashfs
 Output information may be incomplete.
 lsof: WARNING: can't stat() ext2 file system /live-rw-backing
 Output information may be incomplete.
 Possibly no one blocking sound access, so ran Kaffeine, which worked
   Following which ran
 
 Code: 
kanotix@Kanotix:~$ lsof | grep pcm
kaffeine- 3538    kanotix  mem       CHR      116,3             10697 /dev/snd/pcmC0D0p
 kaffeine- 3538    kanotix   19u      CHR      116,3       0t0   10697 /dev/snd/pcmC0D0p
 
 TheOne hat folgendes geschrieben:: 
Try to increase volume of PCM and Master channel.
 Kano hat folgendes geschrieben:: 
Usally you need to increase front too.
With Kaffeine running, ran 'alsamixer' and was able to adjust contols and eliminate unnecessary ones  -> ->

 Checked sound file device
 
 Code: 
kanotix@Kanotix:~$ lsof | grep pcm
plugin-co 4739    kanotix  mem       CHR      116,3             10697 /dev/snd/pcmC0D0p
 plugin-co 4739    kanotix   20u      CHR      116,3       0t0   10697 /dev/snd/pcmC0D0p
 
 Flash Plugin seems to always grab the sound device file, but this time appears to have relinquished it to the active process. It is this same plugin plugin-co which had the sound device file before, when nothing was happening. So it remains a puzzle as to why this plugin now seems to be behaving properly.
     
 Attached file lists all processes on m/c., and maybe s.o. can spot one which could have been responsible for locking out processes from the sound device file.
