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.
45 * Some stability problems when unloading the snd-p16v kernel module.
