The ALSA homepage says:
*** N.B. The 0.5.x series is considered deprecated
and is no longer supported by ALSA developers ***
In 0.9.x, the ALS100 uses the code for SB16, which says:
* Note: This is very ugly hardware which uses one 8-bit DMA channel and
* second 16-bit DMA channel. Unfortunately 8-bit DMA channel can't
* transfer 16-bit samples and 16-bit DMA channels can't transfer
* 8-bit samples. This make full duplex more complicated than
* can be... People, don't buy these soundcards for full 16-bit
* duplex!!!
* Note: 16-bit wide is assigned to first direction which made request.
* With full duplex - playback is preferred with abstract layer.
