</div>that's what it is... it's the same graphic controller as a nvidia<br>
9400M... audio channels are incorrectly ordered on that card.<br>

</div>what were your settings previously?<br>
<div><div><br></div></div></blockquote><div><br></div></div><div>I hadn't changed settings previously, just upgraded from 0.25 to 0.26 and then a couple of days after that noticed the clipping/crackling coming from the rear surround speakers. I notice it on the left rear the most.</div>
<div>Previous setting did not upconvert to 5.1, had just enabled DD, DTS, and all the other checkboxes. In the track I have been testing, the sound is just two channel. Device is configured as alsa:hw. I am off topic for the original thread now...</div>
<div><br></div><div>I did some more testing tonight. bluray track via bluray player, very loud and no issues. The track I was playing through mythtv that sounds terrible, I played through my Roku3 and Plex and it sounds perfect.</div>
<div>I am going to switch the hdmi inputs on the back of the receiver to confirm that it is not the receiver input. I'm also going to load VLC onto my frontend and play the file through it to see if it is OS related rather than mythtv.</div>

I get the same poor sound quality through vlc so it is not related to my upgrade from 0.25 to 0.26. At the same time, I upgrade the OS (apt-get update;apt-get upgrade) so perhaps it was introduced there...</div>
<div style>It still could be the input on the receiver. Pulling the receiver out to switch the inputs is a pain.</div><div style><br></div><div style>Cheers</div><div style><br></div><div style>Phil </div></div></div></div>
