In the same computer some of the linux's have sound and some not. The motherboard is ASUS M2V-MX SE, Audio: Realtek ALC662-GR Azalia 6 channel audio CODEC.
In all of the linux's Alsa v.1.0.14 emulation code except in sidux .15, and HDA VIA VT82xx (alsamixer)
Linux ........... kernel
Frugalware .. 2.6.22-fw6 SMP
Mandriva ..... 126.96.36.199-laptop-lmdv
Mint 4 GG .... 2.6.22-14 generic
sidux ........... 188.8.131.52-slh-smp
Ubuntu GG .. 2.6.22-14 SMP
Why no sound in Mint when Ubuntu has sound? For ex. Amaroc can not play a cd where there are only waw-files.
I reinstalled linux-sound-base, alsa-utils, alsa-base, and some mint-specific packages but that did not help.
