Anything else?

Idk how to write a good issue its my first time ^^
btw i loveeeee waveflow its perfectttt thankyou :)
this issue is not that bad and also i downloaded it from winget

Thanks for the report, and especially for the logs, they made this traceable.

What we found. Your logs show WaveFlow repeatedly failing to open the output in exclusive mode with 0x8889000A ("device already in use"), then falling back to shared mode. We tracked down one cause: when the headphones you picked are no longer connected, WaveFlow quietly falls back to the default device, your laptop speakers. If it was already holding those speakers in exclusive mode, switching devices tries to open them a second time, Windows refuses because WaveFlow itself is the one holding them, and that is the loop in your log. It also explains why killing WaveFlow from Task Manager fixes it: that releases everything it was holding.

The fix is in #606.

What we're not sure of yet. We haven't been able to reproduce the complete silence you describe, our test machine has no Bluetooth headset, and your log shows two separate moments (04:58 and 06:20) while you describe a single symptom. So we can't yet promise #606 covers the silence too. Three things would settle it:

1. When there's no sound, does it come back if you turn off Settings → Audio → WASAPI exclusive mode, without restarting WaveFlow?
2. With that setting off from the start, does the problem happen at all when you follow your steps (disconnect the headset, open WaveFlow, play a FLAC)?
3. Which headset model is it, and when WaveFlow switches to the laptop speakers, do they produce any sound at all, or is it silent everywhere?

Until a release ships the fix, keeping WASAPI exclusive mode off should very likely avoid this, and whether it does is itself the most useful answer you could send us.

Thx for your response ^^

Turning off the WASAPI fixed the issue and its back to normal.
the complete lack of sound i describe is true like it just doesn't play any sound and when i try to switch the output device it will say that error (i attached the screenshot).
i don't think my headphones model affect that much cuz my usb iem were also doing same.

anddd thxxxx for solving my issue i also have some feature requests too :3

Thanks a lot, that answer settled it! ^^

Your logs line up with two separate bugs, both in the WASAPI exclusive path, which explains why turning exclusive mode off makes everything work normally:

1. The silence. When your headphones aren't available, WaveFlow falls back to the laptop speakers. In your log, those speakers are opened using a 24-bit-in-32-bit format. WaveFlow 1.7.0 packed that format incorrectly, making the signal about 48 dB quieter, roughly 250× lower in amplitude, so the track was technically playing but was basically inaudible. That's already fixed for the next release in fix(audio): left-align 24-bit samples in the 32-bit WASAPI container #520.

2. The error when switching devices. WaveFlow could still be holding the speakers in exclusive mode while trying to open them again during the device switch. Windows then rejects the second open as "device in use". WaveFlow shows this as "no longer available", which is misleading: the device was busy, not gone. That's the bug fixed by fix(audio): release the device before reopening it exclusively #606.

Your USB IEMs doing the same thing also makes sense, it doesn't appear to be specific to the headphones themselves, but to what happens when the selected output disappears and WaveFlow falls back to another device while exclusive mode is enabled.

Until the next release, keeping WASAPI exclusive mode off is the best workaround.

And please do open issues for your feature requests, I'd love to read them! :3
