is it staying in sync over a period of time for you?EddieP wrote: ↑Mon Jan 15, 2024 11:24 amThanks I was getting out of sync audio your suggestion above fixed for me on my new FireTV max.signde wrote: ↑Sun Jan 14, 2024 7:31 pm Picked up the latest (2023) Amazon Fire TV stick 4K Max today.
The two remaining major networks in ATSC 3.0 here that have not enabled DRM are now using 5.1 channel audio that I wanted to leverage.
Initial runs of the app with no audio configuration, passthrough, and 5.1 surround all resulted in some flavor of PCM that was various levels of terrible. One option was low volume, one was high volume with crazy boomy bass, and all had bad 5.1 mixing / sounded heavily compressed.
Changed AFTV stick surround sound settings from the default of best available to Dolby Digital Plus, changed HDHR app output to passthrough. AVR is now showing 5.1 channels of DD+ audio input and everything sounds perfect. I think the default AFTV audio setting must be useless.
Quite pleased with the results here.
after getting this set up, over the last two evenings on two different ATSC 3 channels i have noticed after some time the audio drifts out of sync on this device in this configuration. if i change the channel or quit the app and come back, the audio will be in sync again. after ~10 minutes or so it will have drifted back out of sync.
the same 3.0 channel on a different device using the cloud transcode service is fine as is the ATSC 1.0 version of the channel on the same firestick device.
