[ALSA] pcm_oss - fix SNDCTL_DSP_GETOPTR not working correctly
ALSA<-OSS emulation This patch changes snd_pcm_oss_bytes() by adding a local variable for the frames -> bytes conversion, which means that the frame count is no longer corrupted by this conversion. Signed-off-by: Roger Mach <bigmach@us.ibm.com> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
