Hello, Thank you. These are the differences of the two logs: http://pastebin.com/nAtnhMvc As I am not a really experienced user, I do not know how to add and configure the modules properly. It would be nice if you would explain this in more detail. This is the modinfo on the three sound modules installed on Knoppix: http://pastebin.com/ADknBwRt And this is the output of the alsa-info skript you mentioned - On Knoppix: http://pastebin.com/fHCguzr6 , On Debian: http://pastebin.com/0rAPiyEN . Best Regards Savio PS: I hope the Pastebin Links are ok. I just wanted the mail not get too messy. PPS: As seen in the files, I was wrong saying the there would be a Sigmatel card on Knoppix in /proc/asound/cards. However a Sigmatel codec is used on Knoppix. >Finding out what's different with more detain than Yes and No would help. > >boot into knoppix > >$ lsmod | grep -i "snd" | sort 2>&1 | tee alsa_knoppix.log > >boot into debian > >$ lsmod | grep -i "snd" | sort 2>&1 | tee alsa_debian.log > >save these files on a common medium (flash drive) of course. > >$ diff -a -U 3 alsa_knoppix.log alsa_debian.log > >And of course noting /proc/asound/cards plus you might want to modinfo >the module of importance for each, to see what differs there >(versioning / parms).
