I have run the shell script and here is the output: http://www.alsa-project.org/db/?f=514e34407ba9bad84fe86effa0942e0565747136 I am delighted with help! > > You probably don't have any of the configuration from F10, > but it would > be great if you had run the alsa-info.sh program and saved > the output > so you could run it again and look at the > differences.
