Rodio does not respect macOS output device selection.

When i change the output device rodio continues to play the audio on old device.

Some weird thing here too (MacOS 10.15.6), with the new version (0.12) sink work, play_raw not, sometime Result return the error "no device" and sometime there is no error but no sound either.

Also, if i declare:

let (_stream, stream_handle) = OutputStream::try_default().unwrap();

just before i spawn a thread and append a source to a sink in the thread, there is no error but no sound either.

All is fine if i downgrade the rodio version back to 0.11.

I've no time this day and i'll investigate next week by reading diff between version 0.11 and 0.12, let me know if you want me to open a new topic with more detail.

Edit: I just noticed that sinks also need a thread :: sleep to work properly, without it there is no sound and no errors. It's weird because it forces us to define a minimum duration for each sink played and i don't think this is the expected behavior for it.

Hello! I wonder if there was any progress on this one? I'm also running into this issue.

@dvtkrlbs: I don't think rodio will automatically re-create the OutputStream when the default system device is changed, that's probably something you'd have to check for and do yourself, perhaps by polling cpal::available_hosts().

I have messed around with cpal, and was able to get this to work. Unfortunately, I am no where near familiar enough with rust, audio and osx to make a proper fix. The issue seems to be that cpal generates its AudioUnit with "HalOutput" device from coreaudio, which is related to a specific audio device. If this is changed to "DefaultOutput", librespot starts responding when i change audio output device.

I guess this should be an issue for the cpal project and address how they deal with the osx default output.

PRs (to cpal) welcome!

[kaihagseth]

This issue should be resolved now, through the fix in cpal just above.

I'll leave this open until a new cpal release with the fix is out.
