Don't know if that can help but i moved to 5.8.1 kernel . It works well with my previous workaround : remove ibt- * from /lib/firmware/intel then copy all ibt-* from linux-firmware_1.183.2_all.deb It works fine until an apt-upgrade installs the new latest linux- firmware 1.187.3 . This time i do the first step again but nothing work . So i reinstalled linux-firmware 1.187.3 and i deleted all ibt-12* then update-initramfs -u -k `uname -r` . It works now, until the next update i suppose. This time no firmware it loaded at boot for bluetooth [ 0.130388] Spectre V2 : Enabling Restricted Speculation for firmware calls [ 3.669777] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-56.ucode failed with error -2 [ 3.670121] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-55.ucode failed with error -2 [ 3.670135] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-54.ucode failed with error -2 [ 3.670219] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-53.ucode failed with error -2 [ 3.670417] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-52.ucode failed with error -2 [ 3.670562] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-51.ucode failed with error -2 [ 3.670971] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-50.ucode failed with error -2 [ 3.671106] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-49.ucode failed with error -2 [ 3.676998] iwlwifi 0000:01:00.0: loaded firmware version 48.4fa0041f.0 cc-a0-48.ucode op_mode iwlmvm [ 3.677171] iwlwifi 0000:01:00.0: Direct firmware load for iwl-debug-yoyo.bin failed with error -2 [ 3.789219] i915 0000:00:02.0: [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4) [ 3.858532] iwlwifi 0000:01:00.0: Allocated 0x00400000 bytes for firmware monitor. modinfo btintel filename: /lib/modules/5.8.1-050801-generic/kernel/drivers/bluetooth/btintel.ko firmware: intel/ibt-12-16.ddc firmware: intel/ibt-12-16.sfi firmware: intel/ibt-11-5.ddc firmware: intel/ibt-11-5.sfi license: GPL version: 0.1 description: Bluetooth support for Intel devices ver 0.1 author: Marcel Holtmann <mar...@holtmann.org> srcversion: A42C3539AE01FBB98F673AD depends: bluetooth retpoline: Y intree: Y name: btintel vermagic: 5.8.1-050801-generic SMP mod_unload sig_id: PKCS#7 signer: Build time autogenerated kernel key sig_key: 0F:94:1A:26:3C:C9:CF:EE:A9:9D:5E:55:15:C7:01:C5:AA:C3:30:93 sig_hashalgo: sha512 signature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fo btintel -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1878194 Title: [Sennheiser HD 4.50 BTNC] Bluetooth headset not working when selecting HSP/HFP audio profile in Focal Fossa Status in bluez package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: After updating the release from Ubuntu 19.10 to 20.04, the bluetooth headset doesn't work anymore when HSP/HFP profile is selected. With Ubuntu 19.10 the headset was working, there was audio and the mic was perfect for video conferencing. [Steps to reproduce] 1. Connect headset (used blueman to setup and connect) 1.1. When connected the system automatically selects A2DP profile 2. Start playing audio (browser or other) 3. Change profile to HSP/HFP with pavucontrol (or blueman) 4. The audio disappears and microphone is not working (no input) 5. Optionally switch back to A2DP and the audio comes back [Expected] When switching to HSP/HFP the audio should keep playing and the microphone should start working [Notes] I tried with pavucontrol to switch between profiles while playing audio from a browser. As side note there's a led in the headset that still blinks when switching profile. I tried deleting the pulse folder under user's profile .config without success, also reinstalled packages and did a `sudo alsa force-reload` and rebooting several times. Note: not sure this is a duplicate of [Bug #1576559], it looks quite different since the profile changes but the headset stops working.
