Similar to what is outlined here:
I experience in some cases a metallic / distorted / chirping sound on my Beam2. Happens with Panasonic and LG TV, so it’s not a TV issue.
The metallic sound is somewhat in the background, but clearly noticeable. It is also somewhat correlated to the original sound, seems to be directly „derived“ from it, like a distorted low volume copy.
For me only happens in night sound mode.
When i disable night sound, the issue disappears my.
Seem to happen more often on TV channels with PCM stereo. But I have not been able to relay reliably reproduce it. It happens quite often though.
Switching the channel can make the error appear or go away.
Wild engineering guess is some sort of Bitstream MSB/LSB alignment error. Re-init also means re-align and this can fix it. Possibly hardware not SW?
Anyone else experiencing this?
