So close
For Automatic SPDIF (Optical/RCA) Audio Switch
Reliable and supports 24/192 content.
Unfortunately, the silence detection only works for the selected input, so it keeps cycling between silent sources when nothing is sending valid audio. It fully connects to the source and passes the silent stream on with the source sample rate, so when it switches between inputs with different sample rates, my DAC's relays keep clicking when nothing is playing.
What I'd really need would be a switcher that can immediately switch to the highest priority input that produces non-silent audio, without switching under other circumstances. Admittedly, that's challenging to implement since all inputs have to be actively monitored simultaneously.
If all your sources stop transmitting entirely, this switch can perform as I'd like and switch instantly.
Another issue is that I couldn't get the settings tool to run on Windows 10 Pro 64-bit. No COM ports show up, and adding a legacy device manually fails because the driver isn't signed. I could probably get it to work with Linux, but I couldn't install firmware updates without the tool.
I did contact the maker with this issue, but he basically just said that what I'm describing shouldn't happen. Well.
I'm now using it in a different system to switch between a Chromecast Audio and an HDMI Audio Extractor, which works beautifully since the Chromecast Audio only sends a signal when I cast audio to it. Unlike an automatic TOSLINK switcher from PI Manufacturing, this one doesn't randomly stop working.
Shipping to San Francisco took very long. After the package cleared Chicago, USPS only sent a daily assurance that the package is on the way, without disclosing the current location or a shipping date. Then I didn't get any updates anymore at all for a week, before it suddenly popped up in San Bruno. It took another day to leave that location and only when it arrived in San Francisco, USPS bothered to give me a delivery date. Of course the shipper isn't to blame for this in any way.

Thank you very much for your review :)
Sorry that the COM port is somehow not working on your computer - hard to tell what the problem here is (the used driver is a Windows internal driver which is signed).
