Song playback interruptions

[rockhound]

Hi,

First post here.

I have been experiencing frequent interruption in song playback. System is as follows:

Synology DS214play running MinimServer connected by ethernet to a Synology RT2600ac router, in turn connected by ethernet to a Hegel h190 integrated amplifier. Playback control is via BubbleUPnP running on an Asus Zenpad 8" Android tablet. Minimwatch is running on a 2018 MacBook Pro.

Songs often stop playing within the first 30-60 seconds of starting to play an album, although it can happen pretty much at any time. After approximately 45 seconds it is usually possible to start playback again (from the start of the song). Below is an example of the log during the period when this happens (including successful restarting). I'd appreciate your thoughts on what may be causing this, in particular the line at at the point of playback interruption 13:18:34.329 HTTPConnection: connection closed by client. Does the "client" here refer to Bubbleupnp or the network player module in the Hegel amplifier? The IP addresses referred to in the log are as follows: 101 (Synology NAS); 22 (Hegel amp); 89 (Android tablet).

Thanks so much in advance for your assistance.

It looks like there is a problem with the way the Hegel is reading and buffering the data. The "client" referred to in the message is the Hegel. The log messages show that the Hegel is reading a large chunk of data very quickly and then blocking the connection to MinimServer for a long time (sometimes over 20 seconds) before reading another large chunk. This isn't necessarily a problem if the client is managing its internal buffering correctly but it looks like it might be a factor in triggering the problem you are having with playback interruptions.

As a possible workaround for this client problem, you could try using MinimWatch to set the MinimServer serverOptions property to flowControl=2x (see this section). This forces the client to read the data in smaller chunks and this might prevent the Hegel from closing the connection prematurely and interrupting playback.

Thanks for the very quick reply. I'll give this a go tomorrow and report back. Thanks again.

I'd say there had been some improvement. However, I still experienced a couple of random connection drops, although not right at the start of playing an album as has often been the case previously. I've attached a log file where a couple of tracks played just fine, followed by a random connection drop.

Does the log provide any further clue as to what might be happening, or suggest other potential solution(s)?

Thanks again for your assistance.

[simoncn]

It looks like flow control is working as intended until the client closes the connection and stops playback. You could try changing the flowControl setting from 2x to 3x to see if that helps.

[rockhound]

Great, thanks - I'll give that a try. Thanks again.
