Description fujiwara 2000-07-23 07:40:01 UTC 
	previous pcm driver works fine.
	but with current driver, kernel displays:

pcm0: play interrupt timeout, channel dead

	and doesnot play sound.

Fix: my poor fix is under this.
	my note PC plays good with this patch.
	please correct this problem.

	ES1371 system plays good without/with this patch.
How-To-Repeat: 
	for example: mpg123 *.mp3
