I got a report that the "pcm" driver does not start with small audio
files. This was due to a bug i introduced near the beginning of the
year to optimize performance :)
in any case, the fix is easy and i will commit it in the next hours on
-current (and for -stable, an update to the whole "pcm" code is
coming in): in dmabuf.c, function dsp_wrintr, change one line near
line 183 as follows:
* check if we need to reprogram the DMA on the sound card.
* This happens if the size has changed _and_ the new size
* is smaller, or it matches the blocksize.
*/
- if (l != b->dl && (l < b->dl || l == d->play_blocksize)){
+ if (l != b->dl && (b->dl == 0 || l < b->dl || l == d->play_blocksize)){
/* for any reason, size has changed. Stop and restart */
DEB(printf("wrintr: bsz change from %d to %d, rp %d rl %d\n",
b->dl, l, b->rp, b->rl));
cheers
