Fix HFP mSBC support on Realtek Bluetooth USB controller

[Kai-Heng Feng]

[Impact]
When a BT headset is connected Realtek BT USB controller, HFP profile can't play or record sound when mSBC codec is used.

[Fix]
At Linux kernel side, add a Realtek specific quirk to support mSBC.

At PulseAudio side, send more data frames until the connected device sends response.

[Test]
Connect different headsets to the said controller, HFP can play and record sounds now.
Also verified A2DP profile is unaffected.

[Where problems could occur]
The kernel part is Realtek specific, so the regression risk is very limited.

The pulseaudio side only affects HFP profile, since the codeflow only changes when a mic is present.

Is this actually expected to land in oem-6.0? My understanding is that it's basically done already.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-oem-6.1/6.1.0-1008.8 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

All autopkgtests for the newly accepted pulseaudio (1:16.1+dfsg1-1ubuntu3.1) for kinetic have finished running.
The following regressions have been reported in tests triggered by the package:

Thank you!

[Kai-Heng Feng (kaihengfeng)]

Verified on the following steps:
1) Enabled proposed pocket, upgrade pulseaudio and install oem kernel 6.1.0-1008.8.
2) Reboot.
3) Pair and connect AirPods, play some audio to ensure that A2DP still works.
4) Switch to HFP and I can hear sound. Microphone also works too.
5) Keep switching between A2DP and HFP profile, both of them work all the time.

#9 doesn't seem to be a regression caused by pulseaudio.

[Łukasz Zemczak (sil2100)]

The verification of the Stable Release Update for pulseaudio has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
