Hi Emmanuel, I'm having this problem too, I solved this bug to my user account, making PulseAudio run in System Mode, your is probably running in User Mode, but I have changed my user account and the problem is back, If I solve, I will post here.

Hi everyone ! I'm having an issue with my new motherboard, I just installed Debian sid and I don't have any sound :( I'm pretty lost, so I post here (if it's the wrong place, feel free to tell me), also I launched the latest Ubuntu live and had sound, so I think there is something I missed ;) Here is the result of alsa-info.sh on _Debian_ : http://www.alsa-project.org/db/?f=ea68c55b64250b7278305cf46fdc2873356f6d0c And here is the same, on _Ubuntu_ : http://www.alsa-project.org/db/?f=e10b7f43c8ecbb304b9eef1e7e38dd129488512d >From now, I have no idea what to do... As I said, everything looks perfect on Ubuntu, so I couldn't find on Internet something similar, and all the stuff around ALSA and PulseAudio is pretty obscure to me... In advance, thank you :) -- Emmanuel Bourgerie <email@example.com> Développeur web & Open-Source
