>Description:
Audio doesn't play with the sb device driver and an SB Vibra 16.  I hear a brief noise and then the process gets stuck in aud_dr until some time later when audioplay exits.  I've tried different wav files with the same result.  I also tried a SoundBlaster AWE-32 and found the same problem.  I've tried different card slots on the same motherboard too.

With a -DAUDIO_DEBUG kernel I get this:
$ audioplay test.wav

This is the output from xconsole:
audio_open: flags=0x2 sc=0xc0cd7800 hdl=0xc0ccca00
audio_initbufs: mode=0x5
audio_init_ringbuffer: blksize=2192
audio_init_ringbuffer: blksize=2192
audio_open: done sc_mode = 0x5
audio_ioctl(136,'A',21)
AUDIO_GETINFO
audio_ioctl(136,'A',21) result 0
audio_ioctl(136,'A',22)
AUDIO_SETINFO mode=0x5
audio: Setting play params sr=22050, enc=6, chan=1, prec=16
audio_initbufs: mode=0x5
audio_init_ringbuffer: blksize=2192
audio_init_ringbuffer: blksize=2192
audio_ioctl(136,'A',22) result 0
audiostartp: start=0xc555a000 used=4750(hi=63568) mmapped=0
audio_ioctl(0,'A',23)
AUDIO_DRAIN
audio_drain: enter busy=1 used=4750
audio_drain: used=4750, drops=0

About 20-30 seconds later this output appears in xconsole:

audio_sleep: woke up st=35
audio_ioctl(0,'A',23) result 35
audio_ioctl(0,'A',24)
AUDIO_FLUSH
audio_initbufs: mode=0x5
audio_init_ringbuffer: blksize=2192
audio_init_ringbuffer: blksize=2192
audiostartp: start=0xc555a000 used=0(hi=63568) mmapped=0
audio_ioctl(0,'A',24) result 0
audio_ioctl(136,'A',22)
AUDIO_SETINFO mode=0x5
audio: Setting play params sr=22050, enc=6, chan=1, prec=16
audio_initbufs: mode=0x5
audio_init_ringbuffer: blksize=2192
audio_init_ringbuffer: blksize=2192
audio_ioctl(136,'A',22) result 0
audio_close: sc=0xc0cd7800
audio_close: done

Then audioplay returns with:
audioplay: audio drain ioctl failed: Resource temporarily unavailable

If needed I can get more info about the card from the dmesg.  It seems that my dmesg is full of the audio debug output now, so I can't get it just now.
>How-To-Repeat:
Use audioplay to play a wav file.
