Audio Sync Issues

Post by leog »

Apologies if this has been asked/answered already, go ahead an point me to that thread if so.

I just set up my Flex Duo yesterday and I'm noticing some of the channels I receive have audio that is quite noticeably delayed/out of sync with the video. Many tuners/tvs seem to offer controls to sync this when necessary. Is there a way in my HD HomeRun App to do this? Hope so.

We would like to get some diagnostic data:
  1. Please go to http://hdhomerun.local
  2. If it tells you that a firmware update is available, please install it
  3. Click System Status
  4. Check the Send diagnostic information box
  5. Go back one page
  6. Click Channel Lineup
  7. Click on Detect Channels
  8. After the scan finishes, open the HDHomeRun app
  9. Go into the app settings: the gear icon in the top right corner of the "Live/Recorded/Discover/Tasks" page
  10. Enable the option to "Send diagnostic information"
  11. Watch a problem channel for at least 10 minutes

Reply back to this post and provide us the device ID of your HDHomeRun and we will check the logs. You can find the device ID on a label on the bottom of the HDHomeRun itself.

Thanks, I will do this asap. It may also behave different on different devices, so it that case it is not your fault. Still diagnosing...

By the way, when I try to browse to (MacOS 26.3, Chrome Browser) the local address of my device with the link you shared, I get:
This site can’t be reached
hdhomerun.local’s server IP address could not be found.
Try:

Checking the connection
Checking the proxy, firewall, and DNS configuration
ERR_NAME_NOT_RESOLVED


Using the app works just fine, but something is not allowing me to browse to it directly...

Use Safari. Chrome is sometimes weird about .local addresses, IIRC.

Chrome requires that you type http://hdhomerun.local for some reason. Most other browsers accept hdhomerun.local

I believe chrome defaults to https unless you specify http.
