I switched over to the ALSA driver for my onboard audio chip and I did
not receive the 8 bit per sample warning. However, now when I try the
plib examples and FlightGear I get the following warning messages
respectively "slDSP: write: Resource temporarily unavailable" and
"WARNING: slScheduler: Too many pending callback events! slDSP: write:
Resource temporarily unavailable". These warnings along with a similar
audio configuration were previously reported by Felix Kuhling back on
July 25, 2002. In his mail, Felix provided a patch that fixed his
problem. Is that patch still available and if so can I get it? While
the patch may not be the best approach to fix my audio problem
(ie. the source of the problem appears to be the limitations of the
audio driver itself) it might be enough to get FlightGear running with
sound which is my ultimate goal. Note I did try the OSS/Linux driver
and I did get sound from both the plib examples and
FlightGear. However, I experienced annoying crackling noises which
increased in intensity when moving windows around the desktop. I
messed around with the driver configurations as suggested in the OSS/Linux
mailing but the crackling noise did not go away.

Thanks,
