What would I need to change in the emu10k1 driver, to get alsa-lib to send it 32bit audio samples.
I tried just adding the SNDRV_PCM_FMTBIT_S32_LE to the playback options, but that did not work.
When I did that, everything just played at half speed.
Can anyone give me any pointers as to where else I should change things in order to get 32bit audio to the Audigy2 DSP.
AFAIK, emu10k1 engine processes only 16bit PCM. or do you know the register (or anything else) to handle 32bit data for audigy?

The SB Live DSP can only handle 16bit PCM. The SB Audigy DSP can handle 24/32 bit PCM.
I am working from what someone has told me to get 24bit sound. Send it to the Audigy inside a 32bit value: -
For playback:
You can use voice grouping - alloc 4 FX busses for 1 stereo stream
or use TRAM.
Does this help you ?
