The pipe buffer is likely to be a power of 2 (e.g. 4096 bytes). This works nicely for 16 bit stereo samples but breaks when using 24 bit samples. This patch aligns the buffer using pa_frame_align(). --- src/modules/module-pipe-sink.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/modules/module-pipe-sink.c b/src/modules/module-pipe-sink.c index 0a3a4fc..0eefdf1 100644 --- a/src/modules/module-pipe-sink.c +++ b/src/modules/module-pipe-sink.c @@ -123,7 +123,7 @@ static int process_render(struct userdata *u) { pa_assert(u); if (u->memchunk.length <= 0) - pa_sink_render(u->sink, pa_pipe_buf(u->fd), &u->memchunk); + pa_sink_render(u->sink, pa_frame_align(pa_pipe_buf(u->fd), &u->sink->sample_spec), &u->memchunk); pa_assert(u->memchunk.length > 0); @@ -301,7 +301,7 @@ int pa__init(pa_module *m) { pa_sink_set_asyncmsgq(u->sink, u->thread_mq.inq); pa_sink_set_rtpoll(u->sink, u->rtpoll); - pa_sink_set_max_request(u->sink, pa_pipe_buf(u->fd)); + pa_sink_set_max_request(u->sink, pa_frame_align(pa_pipe_buf(u->fd), &u->sink->sample_spec)); pa_sink_set_fixed_latency(u->sink, pa_bytes_to_usec(pa_pipe_buf(u->fd), &u->sink->sample_spec)); u->rtpoll_item = pa_rtpoll_item_new(u->rtpoll, PA_RTPOLL_NEVER, 1); -- 2.9.0
