Hi,
First of all, I want to thank you for your great work. I only expected it would be suitable for music, but it turns out that the latency is enough for video/gaming.
However, there is an issue: Every time I start streaming the audio is fine, but after some time (I would say about 10-20 minutes) , the audio begins to stutter and crack a lot. Then if I restart streaming it would work well again.
Is there any tip you could show me about this issue? I stream to a Sonos Era 100 btw.

Is your Sonos wired or is it a WiFi connection?
Also, if you're gaming I can imagine that swyh-rs does not get enough CPU to keep up with the audio capturing. You can always try to give it a higher priority in the task manager.

Thanks for your reply.
There's no wired connection, I just connect my Sonos and PC to same Wi-Fi.
I tried to set swyh program to realtime priority in task manager, but the issue remains.
Even when I'm gaming, the CPU usage usually is less than 30%.
Could my network connection quality have something to do with this?

This leaves 2 possibilities that I can see:

  • your wireless network is sometimes too busy, but why only after 20 minutes or so beats me

  • the sample clock of your Sonos runs slightly faster than the sample clocck of your PC, so that inevitably after a certain time the Sonos network delay buffer will get empty because the samples arrive slower than they are consumed, and restarting the music fixes it temporarily.

Edit: from 1.10.5 on you can also let swyh-rs do some buffering, what happens if you enable let's say a 100 msec buffer? Does the time before stuttering begins increase?
