DVB TV HAT sound issues

Sun Jan 13, 2019 3:41 pm

Hello,
I'm trying to set up a DVB TV Hat on a RPi 3B running Kodi/Libreelec and using TVHeadend Server/Client.
All is working great except sound issues using analog ouput : I heard annoying crackles.

HDMI audio output :
- TV = perfect
- all other medias = perfect

Analog audio output :
- TV = crackles
- all other medias = perfect

I tried to change some settings (sample rate...) in Kodi without success.

Any idea or advises ?

Thanks

Add audio_pwm_mode=0 (you could also try with 1) to your config.txt.

There were several reports that the new, optimized analog audio code in the firmware causes issues with live TV (probably due to deinterlacing) and 1080p50/60 playback.

so long,

Hias
