Hello Cameron,
I was curious about your new pcm feeder, so I cvsuped to 4.1.1-STABLE
(Sun Oct 8 00:22:45 CEST 2000) and made world and new kernel.
The SNDCTL_DSP_SETFMT ioctl *always* returns EINVAL :-(
Hardware: SB Live! 1024 / EMU10K1
I turned on some debug switches and got this while trying to
start esd (esound). I have chosen esound because esd tries many
different formats for SNDCTL_DSP_SETFMT before giving up:
installing feeder: 8to16le
installing feeder: 16leto8
installing feeder: monotostereo8
installing feeder: monotostereo16
installing feeder: stereotomono8
installing feeder: stereotomono16
installing feeder: endian
installing feeder: sign8
installing feeder: sign16le
installing feeder: ulawtou8
installing feeder: u8toulaw

Any idea what's causing this?
