For profiles: If you are only interested in music quality audio, then use `-p a2dp-source -p a2dp-sink` which will allow bluealsa to both send and receive a2dp audio. If you...

A2DP emphasizes audio quality over low latency and is therefore best suited to music listening. A typical A2DP codec uses a sample rate of 48kHz 16-bit stereo. HFP/HSP emphasize low...

> Shall I set that value to 0, or just leave it undefined? `defaults.bluealsa.delay` is actually defined in `/etc/alsa/conf.d/20-bluealsa.conf`, so no need for you to define it yourself unless you...

> Bluetooth: hci0: Device does not support ALT setting 6 Yes, that requirement for USB was introduced in Linux 5.8 - see https://github.com/Arkq/bluez-alsa/issues/343 The Bluetooth Core spec does require Alt6...

In the Bluetooth Core Specification, Volume 4, section 2.1.1, Table 2.1: USB Primary firmware interface and endpoint settings, the "Recommended" Host Controller endpoint setting for mSBC voice is Alternate 6....

> But my real question was why settings other than alt 6 can't work. Isn't it possible to use multiple smaller packets to achieve the necessary data rate? well, they...

The PCM interface is a separate hardware interface (different pins on the chip package) and not part of the USB interface. So for external plug-in USB adapters it is not...

@xyzzy42 I think that's an impressive piece of work. If there's any way you could persuade the btusb developers to take note and implement this upstream that would be a...

The patch https://lore.kernel.org/patchwork/patch/1265703/ is shown as "accepted" which I guess, means it will soon appear in the mainline kernel tree? So then it becomes a matter of applying BTUSB_USE_ALT1_FOR_WBS to...
