I am using ProgDVB as IPTV client, my notebook connected with TV with HDMI cable and sound is going through TV speakers.
When I am using ProgDVB there is delay 1-2 seconds from video. I tried all possible combinations of audio codecs - nothing helps.
On the other hand when I am watching the same IPTV source on the same notebook using ott-play.com all works fine - no sound delays. Also VLC player, Windowa Media Player and 5KPlayer doesn't show any sound delays on this notebook and TV setup

What else can be done?

Try change audio renderer in ProgDVB Options to system.

Audio render set up as System, codecs from microsoft, this combination show best result, but doesn't help with delays. I tried all possible combinations codecs and render - nothing help

Try change demux on playback page.

ps: And update audio driver.

Changing demux to microsoft helps. Thank you.
