Originally posted by Classical View PostI tried to use PipeWire on Void Linux a few days ago but I noticed some serious shortcomings. When I start PipeWire on Void I have sound right away, but it plays on my laptop speakers.
I wanted to play a movie on our TV via the HDMI cable and send the sound to the TV. For Pulse you can of course use pavucontrol and select the HDMI output and it will work.
For PipeWire I started looking for GUI interfaces and something recommended is Helvum. I then installed this on Void but this app is completely useless as a GUI for PipeWire compared to eg pavucontrol.
Then I tried QjackCtl. I configured mpv to use jack, and I was able to play sound via PipeWire + mpv on the laptop speakers. But then when I selected the TV or any HDMI output in QjackCtl and I restarted Jack and it couldn't produce any sound in mpv. Although mpv seemed to be configured correctly because it could make sound via Jack, mpv and PipeWire on the laptop.
It seems PipeWire is currently having trouble sending sound to HDMI sources. And I don't think QjackCtl is as user friendly as pavucontrol.

Opus is not part any of the bluetooth audio standards IIRC, there was more details on Pipewire Gitlab merge request for the feature (I vaguely remember glossing over it a while back).
Who knows, maybe some products will eventually adopt it, not sure how it compares to LE audio with Bluetooth 5.2+ (LC3 codec I think?).
There's a few non-standard ones already in-use elsewhere. One company in particular produces a few USB dongle/adapter products with third-parties supporting their codec, so some vendors might be interested in adding opus support too. But other than using adapters, you'd need Windows/macOS/Android to add in support to see broader adoption I think?

Yeah, any linux to linux system using bluetooth with this version of pipewire?

LC3 is just an Opus ripoff with royalty fees, btw.
I'd love to see some headphones adding support to this, but with the BT consortium being this corrupt, I have my doubts.
Still, great news, because we at least solved half of the chicken vs egg problem. Maybe some cheap Chinese knockoffs start adopting Opus to save on license costs or something.Last edited by anarki2; 03 September 2022, 06:57 PM.

Your device could be a linux system that plays audio over bluetooth on a speaker elsewhere nearby connected to a small / cheap SBC also running linux? But I get it, you'd likely have better options when you've got direct control of both OS like that. Maybe though one of those MCU products with bluetooth will come out with the support, I wouldn't be surprised to see it on one of the Espressif (makers of ESP32) products at some point, those are quite affordable (but those RPi Zero's are probably competitive beyond power usage for the same task?)
I use bluetooth headphones (audio only, no mic) and it works well enough (AAC). I don't know if I'd have an issue with a mic over bluetooth, but I don't see the quality of the mic hardware itself worthwhile (ignoring bluetooth audio profiles), they're just for convenience vs a proper mic.
