I have done a fresh install of debian recently (installed lenny and performed a dist upgrade to sid) and after updateing my kernel to 2.6.23 I lost sound. after some tweaking I at least have my sound card detected correctly and if I open the gnome-sound-properties applet I can test the sound output and I hear the tone. however in the same applet if I go to the sounds tab and attempt to play one of the "system sounds" I have no joy, also I have no sound anywhere else in debian...

I have done chmod 777 /dev/dsp and have also checked alsamixer, which does detect my card... still no sound.

last thing, I know the hardware is working, because as I said If I test it in gnome-sound-properties, it generates a tone.

what am I missing?

nevermind, I found a fix:

I spoke too soon, the problem persists... however, I have sound... allow me to explain, I have no system sounds. so the sounds generated in gnome-sound-properties dont work... I can open the sound waves themselves and play them fine, but the system simply does not generate sounds... any ideas what Im missing for this?

I realise this is an old post, but I ran into a similar problem when I installed Lenny recently. In my case, I could play music, but couldn't get any sound from quake. All I had to do was add the following line at the beginning of /etc/modprobe.conf
