|
|
|
|
*
|
|
|
|
|
* FEATURES currently supported:
|
|
|
|
|
* Output fixed at S32_LE, 2 channel to hw:0,0

|
|
* Changelog:
|
|
|
|
|
* 0.8
|
|
|
|
|
* Use separate card based buffer for periods table.
|
|
|
|
|
* 0.9
|
|
|
|
|
* Use 2 channel output streams instead of 8 channel.
|
|
|
|
|
* (8 channel output streams might be good for ASIO type output)
|
|
|
|
|
* Corrected speaker output, so Front -> Front etc.
|
|
|
|
|
* 0.10
|
|
|
|
|

|
|
|
|
|
* Add Analog volume controls.
|
|
|
|
|
* 0.12
|
|
|
|
|
* Corrected playback interrupts. Now interrupt per period, instead of half period.
|
|
|
|
|
* 0.13
|
|
|
|
|
* Use single trigger for multichannel.
|
|
|
|
|
* 0.14
|
|
|
|
|
* Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
|
|
|
|
|
* 0.15
|
|
|
|
|
* Force buffer_size / period_size == INTEGER.

|
|
|
|
|
* Update p16v.c to work with changed alsa api.
|
|
|
|
|
* 0.17
|
|
|
|
|
* Update p16v.c to work with changed alsa api. Removed boot_devs.
|
|
|
|
|
* 0.18
|
|
|
|
|
* Merging with snd-emu10k1 driver.
|

|
|
* One stereo channel at 24bit now works.
|
|
|
|
|
* 0.20
|
|
|
|
|
* Added better register defines.
|
|
|
|
