Description shirai 2000-08-01 13:00:01 UTC 
According to OSS Programmer's Guide (http://www.opensound.com/pguide/),
SNDCTL_DSP_GETODELAY returns the number of unplayed bytes in the
kernel buffer. It means the length of ready areas (rl). But, in
the latest implement, this call returns the total bytes played
already. It is certainly mis-implement.

Fix: The following patch will be effective:
How-To-Repeat: Use any audio applications which use SNDCTL_DSP_GETODELAY.
e.g. TiMidity++ (>= 3.5.1)
