I have seen this before but it was due to the HDMI cable. They have chips inside of them and if they can't 'talk' correctly with one side or the other, they drop sound (aka to stop you from pirating etc). I would try a different cable and see if that makes any difference.
Hi!
Had tried this. tired 3 caables. all behave same:
- all works fine with kodi or raspian (Linux cam.local 4.14.71-v7+ #1145 SMP Fri Sep 21 15:38:35
BST 2018 armv7l GNU/Linux ) on both tv
actualy.. on raspbian, aslamixer is not same as in f29. It is same for default, but it have control for the v4l-hdmi (just calls it bcm245..whatever according to theirs custom driver)
- all works fine with f28 on newer tv, none work with f29 on older tv
so cable out of guilt:(
thanx a lot! j.

Hello!
I have f29 (kernel-4.18.12-300.fc29.aarch64 ) on machine, which is changing its place from time to time - between two TVs. Old, and older:)
Both are connected by HDMI. Video output is fine, even acceleration is working, but sound work only on newer of those two.
I don't know if this is regression, because this machine replaced 32b rapbery2 with kodi, which was working without issues on both TVs (but was eaten by (not mine) dog)
I was following https://fedoraproject.org/wiki/How_to_debug_sound_problems but had not found much:
with removed pulseaudio, the aplay -vv segfaults
- I really on pulseaudio anyway, as I need to transfer sound to this machine over network
the diff of alsa-info.sh's is really minimal [1], only
[cite] state.vc4hdmi { control.1 { iface PCM name ELD value '100007006712000100000000000000004c2d9d02 for non working and value '100007006712000100000000000000004c2d9b03 for working [/cite]
- when alsamixer is opened, then the default looks like working, and the job on old tv; but not do
nothing older tv.
- when alsamixer -c0 is opened, then the vc4-hdmi reports no control for selected device for
*both* tvs (which is same as f6 and selecting vc4-hdmi)
Does anybody have a clue what to try?
Thanx in advance form java world, J.
