8  *    Output fixed at S32_LE, 2 channel to hw:0,0
15  *    Use 2 channel output streams instead of 8 channel.
16  *       (8 channel output streams might be good for ASIO type output)
17  *    Corrected speaker output, so Front -> Front etc.
36  *    Merging with snd-emu10k1 driver.
38  *    One stereo channel at 24bit now works.
42  *    Integrated with snd-emu10k1 driver.
50  *    setting HD Capture channel to 0 captures from CDROM digital input.
51  *    setting HD Capture channel to 1 captures from SPDIF in.
56  *    Some stability problems when unloading the snd-p16v kernel module.
