<div><font>Hi guys,</font></div>
<div><font><br>
</font></div>
<div><font>I found a issue about stuttering when recording sink
monitor audio, as shown below:</font></div>
<div><font><br>
</font></div>
<div><font>
<div>Preconditions:</div>
<div>1. The sound card only supports software volume.</div>
<div>2. Two audio players play different audios at the same
time.</div>
<div>3. Set to speaker output audio.</div>
<div><br>
</div>
<div>Test steps:</div>
<div>1. Record the audio stream of the monitor of the speaker
sink through parec.</div>
<div> For example: parec -d
alsa_output.platform-raoliang-sndcard.analog-stereo.monitor
--file-format=wav test1.wav</div>
<div>2. Change the volume of the speaker sink during
recording.</div>
<div>3. It will cause stuttering in the audio stream recorded
from the monitor channel of the speaker sink.</div>
<div>4. However, the audio output from the sound card speaker
does not stutter.</div>
<div><br>
</div>
<div>Could you tell me why this problem occurs? thanks a lot.</div>
<div><br>
</div>
<div>Cheers,</div>

<p>Hi,</p>
<p>which version of PA are you using? That behavior has been a known
bug in older versions,<br>
but at least version 16 or the recently released 17 should not
show that issue.</p>
