Amancio Hasty:
|I need a little more info.
|
|in dmabuf.c:dma_sync
| while (!(out_sleep_flag[dev].aborting)
| && audio_devs[dev]->dmap_out->qlen) {
|
| int flag, chn;
| printf("dmabuf %d \n", audio_devs[dev]->dmap_out->qlen);
|
|Add the above printf and please send me the output of the last few
|lines .
Ok, here it is:
> mpg123 things.mp2
-----> APP STARTUP PRINTS:
start sb_reset_dsp
done RESET 1
done tenmicrosec
done RESET 0
isa_dmastart: channel 5 busy
-----> THEN WHEN I CTRL-C, I ALWAYS SEE THIS:
dmabuf 2
dmabuf 1
-----> IF THE /dev/dsp close() DIDN'T HANG, THAT'S IT.
-----> BUT IF THE close() HUNG, I SEE THIS LINE AGAIN AND AGAIN, PRINTING
-----> ONCE EVERY 10 SECONDS:
dmabuf 1
