Hi Iain,

thanks for the new version of dmasound. I went through the tests with
stest you suggest and all passed well on my pismo. However I had one
kernel oops which is listed below if you can find any useful info from
it. I tried with more recent ksymoops, the warnings about reliability
are still there and the report is different.
cheers

current settings:
sound.format = 0x20 (signed 16 bit BE)(Phys: signed 16 bit BE)
  sound.speed = 44100Hz (phys. 44100Hz)
  sound.stereo = 0x1 (stereo)
  write_sq.block_size = 16384 write_sq.max_count = 4
