Hi all, It works for me on Asus Vivobook after have applied firmware linux- firmware_1.183.2_all.deb on Ubuntu 20 on kernel 5.4.0-42-generic . Don't know how. dmesg | grep firmware [ 0.139854] Spectre V2 : Enabling Restricted Speculation for firmware calls [ 3.107460] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-50.ucode failed with error -2 [ 3.107485] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-cc-a0-49.ucode failed with error -2 [ 3.112097] iwlwifi 0000:01:00.0: loaded firmware version 48.4fa0041f.0 op_mode iwlmvm [ 3.188788] [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4) [ 3.193324] Bluetooth: hci0: Minimum firmware build 1 week 10 2014 [ 3.195221] Bluetooth: hci0: Found device firmware: intel/ibt-20-1-3.sfi [ 3.197148] iwlwifi 0000:01:00.0: Allocated 0x00400000 bytes for firmware monitor.

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.
