Description protius 2000-09-19 03:50:02 UTC

When recording audio with the pcm device driver, there is continuous static in the audio.  The "real" audio is also present, the static acompanies it (on both channels).

pcm0: <OPTi931> at port 0x534-0x537,0x380-0x38b,0x220-0x22f,0xe0c-0xe0f irq 5 drq 0,1 on isa0
AD_WAIT_INIT FAILED 1002 0xff

FreeBSD Audio Driver (newpcm) Sep 10 2000 12:18:34
Installed devices:
pcm0: <OPTi931> at io 0x534 irq 5 drq 0:1 (1p/1r channels duplex)

How-To-Repeat: http://www.bobdbob.com/~protius/software/tsplay.c  <-- small test program.

Record something with the above program, calling it with the name tsrec.  
Then play the same audio back, with the above program calling it with the name tsplay.

Cameron can determine best if this is still a problem.

This will have to be put on hold until I can get ahold of one of these (evil) 
cards.

Is this still a problem with modern versions of FreeBSD?
