Hi, After boot the sound, although, barely, understandeable, is mixed with noise (Different sound players - from aplay to amarok). The problem goes away through running something along the lines: lsmod |grep snd|awk '{print $1}'|xargs -n1 modprobe -r; modprobe snd_hda_intel Sound worked perfectly on 2.6.25 and im quite sure it did on the 2.6.25 git kernels before 2.6.26-rc1 was released - unfortunately I didnt test sound in 2.6.26-rc{1,2,3} so I cant yet say where exactly the problem originated. If necessary I will do a bisect but I would be happy if it wouldnt be neccessary... Which additional information do you need / which patch do you want to get tested? Thanks, Andres PS: Exact version I am running now is: 1ec7d99c16e69a9ed8ffeaa6c1846025b84bebad PPS: Laptop is a IBM/Lenovo T60
