Description of problem: If I switch to my Bluetooth headset and enable the microphone there, no sounds get's recognized. Version-Release number of selected component (if applicable): 1.2.4 (utilities) k5.9.11-200.fc33.x86_64 (driver) How reproducible: Always. Steps to Reproduce: 1. Connected Bluetooth headset. 2. By default it still uses my internal microphone and Bluetooth only as audio output. 3. As I have pulseaudio-module-bluetooth-freeworld installed, it uses the apt X HD codec by default, which is great and okay. 4. Now switch to microphone input from the Bluetooth headset. Actual results: 1. The audio *output* is still shown as aptX HD, but I can hear it is clearly HSP/HFP this is hearable. Also if I now choose "Test" in the GNOME settings there, it shows me a mono (not stereo) output, evem * Sometimes it seems to show my audio input (microphone) in the "audio output" bar in the settings, i.e. totally in the wrong section. Does not happen always though. I also could not find out whether this is now the internal microphone or the external (Bluetooth) one. * The microphone setting in GNOME Settings there is always one red "progress bar partition" (no errors are indicated) instead of the audio/volume recorded. See https://aws1.discourse-cdn.com/business4/uploads/askfedora/original/2X/3/357dd8acbf4f6996158f4b8af6b3dc0f85e880a0.png * When my settings are set to HSP/HFP before switching microphone on, and I *then* switch to "aptX HD" it does **automatically** switch my microphone back from external to internal – as if it noticed an error and wants me to use my internal one. (I can, thozgh, switch it back to external and then see the bug just described.) * Sometimes when I switch the codecs (especially between low and high quality) it disconnects from the headphones and connects again. (This may be expected though. Dunno.) * LDAC does not seem to work at all. I can select it in GNOME Settings, however, it I know it has no effect, because if I have selected HSP/HFP) before, I hear no difference and still awful audio. Expected results: It should keep aptX HD (that's what this is for – or any codec I use, it also does not work with any other codec) and also allow me Let me freely choose the external microphone (Bluetooth headset) too. This worked properly in Fedora 32(!). Workarounds: The workarounds from bug 1892115 are already applied and do not help: $ cat /etc/modprobe.d/alsa-dmic-WORKAROUND-bug1892115.conf options snd-rn-pci-acp3x dmic_acpi_check=0 This is the minimal workaround shown in bug 1892115 comment 13 currently that makes the internal microphone work, at least. Possibly important: * I do have pulseaudio-module-bluetooth-freeworld from rpmfusion layered, but IIRC this issue also happened *before* I did so, so I guess it is a bug in here. * Same as bug 1892115 it may be related to the AMD processor. (AMD® Ryzen 7 4800u with radeon graphics × 16), but – as said – is not solved by that workaround there, at least. * As said, switching to the internal microphone still does not make that audio output issue disappear. I do need to switch to HSP/HFP at least and back to aptX HD, then it works again. * Using interal *speakers* and *external* (Bluetooth) microphone, does not make a difference.

It seems like a pulseaudio bug. Bluetooth audio is handled via PA.

This message is a reminder that Fedora 33 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '33'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 33 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 33 changed to end-of-life (EOL) status on 2021-11-30. Fedora 33 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
