Hi Peter,
Its more of an electronic screeching noise than static. I could record
a short clip of it if you want to see it/hear it.
It happens about 75% of the time when starting a video or if I fast
forward (including commercial skip). I have waited for 5-10 seconds
to see if it will go away but it doesn't. A quick rewind makes it go
away 100% of the time. It is annoying enough, we have started watching
commercials to avoid the sound.
Prior to the shield, I had a computer running MiniMyth2 and never saw
this issue. I also didn't see this with the android packages on the
shield until just about ~10 days ago. As I mentioned, the issue
appeared without any update to the mythtv package on the machine. It
was the older August package. In the interim, there was the Shield
7.1 update. Then I updated to your Sept. package in hopes of a fix, but
it continues to exist.

How can I get the logs with adb? I thought you had sent me a note
previously, but I am not finding it now.
Also, any thoughts on why the other pass through audio modes like EAC3,
TrueHD, etc are not even selectable? Are those not supported on the
Shield? When I try to scroll down to them, the menu just wraps between
Dobly and DTS and won't go down that far.
