<div dir="ltr">I don't know if it is related but I am also getting crackling playing video files through myth. This is a recent change for me and may have been introduced after a recent update. Other sources do not show this behaviour. This is not through USB, it is out HDMI and into a receiver.<div>
<br></div><div>I tried upmixing to AC-3 within mythtv to see if that made a difference but the crackling was still there. Interestingly, upmixing to AC-3 mixed all the audio channels up.</div><div><br></div><div>Cheers</div>

<div>I've been using MythMusic for some time without issue. However I
recently added a usb dac (Micromega MYDAC) to my system and have
connected it via usb. When I play my files (flac mostly) through the dac, I get a
soft crackling sound in the background. </div>
<div> </div>
<div>I <font>believe</font> this is something within my myth setup as aplay and
mpd both work fine through the same usb output using the same ALSA<font> device.</font> With aplay, I converted the file to .wav and ran aplay
-Dplughw:1,0 it.wav. I even did a blind a/b test with my
wife and she can hear the crackling with myth vs aplay as well.</div>
<div> </div>
<div>I'm an running 26-fixes 3587b8240a5 on gentoo 3.6.11 and have attached my log file with -v audio,general.</div>
<div> </div>
<div>Anyone else out there using a usb output for audio?</div>
<div> </div>
<div>Thanks</div><span class="HOEnZb"><font color="#888888">
