I can't seem to get the audio working on my laptop. After installing oss I get the following from ossinfo:
Version info: OSS 4.0 (b1015/200803241124) (0x00040003)

And osstest tells me (in part) "Device is in use (by PID 0/SADA)" and doesn't produce any sound. Should I disable SADA? If so, how is that done? Is the unknown codec the problem or is it SADA? Thanks, in advance, for any input - it's most appreciated.
