Hi @unixweb, this was indeed a bug. The provided number of audio channels was ignored and the default is 2. So, no matter what you entered there, it always tried to configure it as a stereo device, which fails if the device doesn't support that.

I fixed the bug in the dev branch of the UI (datarhei/restreamer-ui@546024fc90f309a41361dffd69868cec42f65377)

I will try to update the datarhei/restreamer:dev Docker image, so you can check out the fixes.

unixweb commented 11 months ago

You will update both Docker images for datarhei/restreamer:dev and datarhei/restreamer-rpi:dev ? Give me a ping if there is an update available please. Thank you very much for this quick fix.

ioppermann commented 11 months ago

The latest datarhei/restreamer:dev and datarhei/restreamer:rpi-dev are now available for you to pull.

Still the same issue

ioppermann commented 11 months ago

That's true. The latest fixes in the UI didn't make it into the dev Docker images. I will check that.

ioppermann commented 10 months ago

The dev and rpi-dev images are now updated and contain the fix for USB audio devices. Please make sure that you properly reload the UI, otherwise the old version might get loaded from the browser cache.

unixweb commented 10 months ago

It works now in general but there is now an another issue. After an hour of operation, the audio and video are no longer in sync and the stream itself keeps interrupting. Should I open a new issue about this?
