Rasberry Pi 4 runing RoPieee (XL, version 413) into Chord Hugo by USB
Description Of Issue
The two audio devices above are grouped into one zone. Although they are usually (but not always) in sync when I start playing to that zone, they often get out of sync during playback with the Naim being ahead of the Hugo. Pausing and then restarting playback always brings them back into sync,for a while at least. I generally just play FLACs from a NAS but it also happens with Tidal
I think I can exclude the Chords. First, it still happens if I play directly from the Naim bypassing the Qutest. Second, it doesn’t happen if I play to a Chromecast group containing the Hugo and the Naim.
Are there I any settings I can tweak as the first thing to try ?
This setting is primarily used when an S/PDIF, AES, or I2S connection is involved. Oftentimes, a DAC will take a little bit of time to lock onto a new audio signal–sometimes as long as a few seconds.
This setting causes Roon to play a configurable duration of silence whenever it begins a new stream. Like the last setting, this one is a problem solver. If you find that the beginnings of songs are being cut off, or you’re getting a lot of clicks and pops while your DAC locks on to an S/PDIF signal at the start of playback, try increasing this setting. 500ms is a good starting point. If that doesn’t work, try gradually increasing it from there.
We default this to a very small value because it produces delays in Roon’s user experience. Consider that when setting it up–unless you have an uncommonly slow DAC, settings longer than 1-2 seconds are probably not necessary.
I’ve added 500ms delay to both. I’ve also changed audio volume from ‘Device’ to ‘Fixed’ since that’s more appropriate for my setup. Don’t recall fidlling with that so guess ‘Device’ is the default. Anyhow, I used it a lot on Saturday and the sound kept in sync throughout so hopefully that’s sorted it. Cheers
