Subject: [PATCH 10/10] pcm_plugin: fix delay
|
|
|
|
PulseAudio ALSA modules report errors after calling
|
|
snd_pcm_avail_delay(), with a delay lower than the number of samples
|
|
available.
|
|
|
|
Correct delay using Jaroslav's recommendation:
|
|
"the result should be 'delay(slave) + mmap_capture_avail(pcm)"
|
|
