https://bugzilla.kernel.org/show_bug.cgi?id=215576 Bug ID: 215576 Summary: HSP/HFP mSBC profile broken with QCA6174 Product: Drivers Version: 2.5 Kernel Version: 5.16.7 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: mike@xxxxxxxxx Regression: No Created attachment 300405 --> https://bugzilla.kernel.org/attachment.cgi?id=300405&action=edit dmesg with 5.16.7 Between v5.15 and v5.16, mSBC via pipewire stopped working with the QCA6174 adapter. Switching to the HSP/HFP profile with mSBC codec in pipewire produces a loud buzzing sound, and the microphone does not function. When using PulseAudio instead of pipewire, the buzzing is absent but audio input/output also don't work. Other users are reporting the same issue at [1]. I ran a git bisect between these two versions and the issue seems to have been caused by this commit: [b2af264ad3af437238c9500aa830ebcafb180e05] Bluetooth: Add support for HCI_Enhanced_Setup_Synchronous_Connection command [1] https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2019 -- You may reply to this email to add a comment.
