Originally pointed out by Georg Chini.
Calculating buffer = buffer + (send_counter - recv_counter)
in one branch and buffer = 2 * buffer - (recv_counter - send_counter)
looks very obviously wrong. In other words, before the patch, the
contribution from the previous lines was double-counted.
if (u->latency_snapshot.recv_counter <= u->latency_snapshot.send_counter)
buffer += (size_t) (u->latency_snapshot.send_counter - u->latency_snapshot.recv_counter);
else
- buffer += PA_CLIP_SUB(buffer, (size_t) (u->latency_snapshot.recv_counter - u->latency_snapshot.send_counter));
+ buffer = PA_CLIP_SUB(buffer, (size_t) (u->latency_snapshot.recv_counter - u->latency_snapshot.send_counter));
buffer_latency = pa_bytes_to_usec(buffer, &u->sink_input->sample_spec);
