Subject: [PATCH 04/43] pcm: dshare: enable silence
|
|
|
|
This issue depends on system load - if the process using dshare is
|
|
scheduled fast enough, then there is no noise. A delay of e.g >~2ms
|
|
produces hearable noise.
|
|
|
|
Reproduction with instrumented aplay(sleep every 100th period for a
|
|
given time):
|
|
During the sleep time of 2000000us (2s) the hardware plays old samples
|
|
in a loop before xrun is detected and recovered after the sleep.
|
|
This is resolved by placing it in silence, in case of dshare plugin.
