No sound from AudioPro A26 #74

Hi, I'm trying to use your app to stream my computer sound to our AudioPro A26 wifi speakers. I've managed to stream to them using the bubbleupnp mobile app and using pulseaudio-dlna, but it was not without alot of lag - so trying this in hope that it'll be in sync :)

Anyway, I can build and run the app without issues on my laptop (Manjaro os). The speakers pop up as an available renderer and when I set the format option to FLAC and start streaming I can hear the speaker "turning on", like they're on but got no sound.

Looking at the debug log in the app it seems the streaming starts and immediatly turns off? See the last few lines:

Configuration { server_port: Some(5901), auto_resume: false, sound_source: "pulse", sound_source_index: Some(1), log_level: Info, ssdp_interval_mins: 1.0, auto_reconnect: false, disable_chunked: false, use_wave_format: false, bits_per_sample: Some(16), streaming_format: Some(Flac), monitor_rms: false, last_renderer: "WiiMu LinkPlayer AudioPro_A26_0695", last_network: "192.168.1.240", config_dir: "/home/jakob/.swyh-rs" }

Thankful for any help - would be awesome to be able to use our wifi-speakers as a playback device for gaming, films, etc.

While swyh-rs does not do any extra buffering, it will never be in sync with video or gaming, unless you can delay the video like VLC can do. By the time an audio buffer, typically 8 KB, has been captured by the OS and delivered to the swyh-rs call-back it is already out of sync, and then it has not even been transmitted to the receiving device.

But this does not explain why flac is not being played. Could you disable chunked transfer, enable the rms monitor, check that the rms monitor shows activity, and then attach a debug log here?
