The interface to LMS is a squezelite modified to be multi-instanciated, but other than that, it's super close to squeezelite in term of LMS protocol. There are 3 levels of buffering, as in squeezelite:
- streaming buffer that receives HTTP stream either from LMS or directly from the internet stream. By default 2MB ==> make the calculation according to the bitrate, but that' a lot - decoder buffer : where the raw decoded data are stored once they are converted to 16/44.1 ==> 2MB again (I think but it's parametric) == 2048/(44.1*2*2) = 12s - output buffer: where the data with replay gain, fading etc is store ==> 2MB again Then raw audio is sent to AirPlay devices by chunkc of 352 samples (=1408 bytes), every 8ms, with 1 to 2 seconds buffering made on the AirPlay device (UDP streaming). I don't think the communication with LMS can be the culprit, there is a lot of buffering. Unless you network is really bad, the AirPlay part is rarely the issue for such long blackout (it's RTP, so lost packets are lost packets, realtime continues no matter what, a blank of 2-3s is a big blackout - thing would be very different with TCP of course), but still it's more sensitive that the LMS part. Note that even if there are lost UDP packets, it does not suspend the LMS connection part, they are independant threads. You could have a "thread starved" for a few seconds, but I don't believe that has any chance to happen - never seen that For me, it's likely the connection between with the internet radio server. As AirPlay bridge (as a squeezelite derivative) can directly stream from the internet radio, it that connection stalls for too long, then you'll have blackouts, no matter what. The 2MB streaming buffer does not change anything here as LMS (at best) tells its's players "get that amount of raw data and then start playing". I have to look at the logs, but it's usually not a lot. I can't remember if that threashold can be changed from the UI. If you can't find any solution, I could build a squeeze2raop that forces that buffer level (before it starts playing) - not very easy to do currently as I'm away from my dev machine, but I can try LMS 7.7, 7.8 and 7.9 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.
