Well, it seems I can answer that myself. After downgrading back to 10.0.4 and noticing the same behavior, and checking thoroughly the sound settings, I noticed that the option "keep the audio source active" was unset. I guess I had it set originally to "Always", but it did get into an undefined state after an upgrade to 11.0.1 and remained after the downgrade as well.
Setting it to "Always" solved the problem.
I have been running LE 10.0.4 on RPi 4, with LG TV (OLED C11) and Sonos Beam v2 without any problems. After an update to 11.0.1, the Kodi UI sounds started to behave erratically. They play fine for a while (when navigating through menus) then stop and after few silent actions, a chirp comes out (as if disconneting/reconnection speakers).
I did not change anything after the update, and the actual TV channel sound seems to be fine (no chirps, or drop outs).
I tried to change different sound settings for the sound in general, but it did not help, neither toggling Kodi UI sound settings for different options.
Anyone has an idea, what might have gone wrong?
I am currently trying to figure out, if there is a way to make dualHD WinTV tuner work on RPi 3B+.
First I took CvH image, but it does not boot on RPi 3B+. I made a naive attempt by copying 3B+ dtd file from Raspbian Stretch, but I guess this was too naive...
Then I noticed that LE9 image may include CvH drivers by default. The problem was I did not find any LE9 images except the ones built by milhouse, and those, while booting fine on RPi 3B+, also support only one tuner.
Does anyone know, what is the expected resolution to this problem? Will LE9 add additional drivers as in CvH's image? Will this be eventually added to milhouse's build? Or will LE9 wait until the support is in the kernel and until the kernel is accepted in LE?
