Synchronising 2 Chromecast Audio about chromecast-desktop-audio-streamer

[SamDel]

There's no automatic synchronization between two devices in the application.

With this little trick you can sync the devices:

• Enable the lag control in the config file which is in the install folder. Set "ShowLagControl" to true.
• (re)Start the application and start the devices.
• Put the lag control slider on 'minimum lag' for a couple of seconds, that will clear the buffers on all devices.
• Then you can put the slider on 'best quality' again, the devices are in sync.

Maybe that process can be automated in a future release.

Hi,

About the lag control, I saw in your code that in fact it skips some audio packets!! It's not really a latency control since it degrades the audio quality!
Why did you manage the latency in this way?

[SamDel]

You're right. When you use the lag control and it's not on the maximum value it removes every x-th packet from the audio stream, reducing the quality. You should only use it when latency is more important than quality.

I was experimenting with it. The only way I could think of to reduce the latency was keeping the buffer on the Chromecast device low.

Version 2.0 supports groups.

You can create groups in the Google Home app and use them in this application to play devices synchronized.

Please let me know if it works for you!
