After exploration, here some note: snd_pcm_drop(pcm) ---> snd_pcm_dmix_drop(pcm) : static int snd_pcm_dmix_drop(snd_pcm_t *pcm) { snd_pcm_direct_t *dmix = pcm->private_data; if (dmix->state == SND_PCM_STATE_OPEN) return -EBADFD; dmix->state = SND_PCM_STATE_SETUP; snd_pcm_direct_timer_stop(dmix); // with or without, still overlapping return 0; } ---> Commented snd_pcm_direct_timer_stop(dmix) gives the same result that uncommented. int snd_pcm_direct_timer_stop(snd_pcm_direct_t *dmix) { snd_timer_stop(dmix->timer); return 0; } ----> Go here ---> int snd_timer_stop(snd_timer_t *timer) { assert(timer); return timer->ops->rt_stop(timer); } ----> Go here ---> static int snd_timer_hw_stop(snd_timer_t *handle) { snd_timer_t *tmr; unsigned int cmd; tmr = handle; if (!tmr) return -EINVAL; if (tmr->version < SNDRV_PROTOCOL_VERSION(2, 0, 4)) cmd = SNDRV_TIMER_IOCTL_STOP_OLD; else cmd = SNDRV_TIMER_IOCTL_STOP; if (ioctl(tmr->poll_fd, cmd) < 0) return -errno; return 0; } And in asound.h: #define SNDRV_TIMER_IOCTL_STOP _IO('T', 0xa1) Maybe this one is not ok ? I did change in snd_timer_hw_stop() ---> md = SNDRV_TIMER_IOCTL_STOP with md = SNDRV_TIMER_IOCTL_PAUSE And compile. Same result, overlapping sound when using snd_drop(). Now checking snd_timer_close() to see what they use, maybe something interesting... int snd_timer_close(snd_timer_t *timer) { int err; assert(timer); while (!list_empty(&timer->async_handlers)) { snd_async_handler_t *h = list_entry(timer->async_handlers.next, snd_async_handler_t, hlist); snd_async_del_handler(h); } err = timer->ops->close(timer); if (timer->dl_handle) snd_dlclose(timer->dl_handle); free(timer->name); free(timer); return err; } ----> Ha, maybe adding part of code in timer_stop(): int snd_timer_stop(snd_timer_t *timer) { assert(timer); // this added: while (!list_empty(&timer->async_handlers)) { snd_async_handler_t *h = list_entry(timer->async_handlers.next, snd_async_handler_t, hlist); snd_async_del_handler(h); } return timer->ops->rt_stop(timer); } No, still the overlapping sound. ;-( So maybe it is not the timer , I dont know... Also I did not find in code the releasing of the remaining buffer after snd_timer_stop(). I think that I will stay happy with your workaround on pcaudiolib....
