# PipeWire notes ## USB headset volume problem 2021-06-14: These files shouldn't even exist, the solution below is wrong, marking the headset as "Pro-audio" in pavucontrol Settings tab is enough to fix it. * * * * * The old pulseaudio fix for less than 20 % volume being unhearable is editing `alsa-monitor.conf` and uncommenting `api.alsa.ignore-dB = true` ``` 2021-049 11:44:40 EET <@wtay> Mikaela, you can set api.alsa.ignore-dB = true in /etc/pipewire/media-session.d/alsa-monitor.conf 2021-049 11:45:31 EET <@wtay> Mikaela, or alternatively: api.alsa.soft-mixer = true in alsa-monitor.conf ``` from #pipewire on freenode which has public logging according to the title. The `api.alsa.soft-mixer = true` may be nicer as the volume is a lot less, 77 % is well audible on USB headset and even 100 % isn't too loud. External speakers with subwoofer again work as usual. 2021-06-14: the above solution is wrong and outdated, the files mentioned don't exist by default anymore, they need to be copied and edited separately See also: * https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1220 * marked as duplicate of: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/207 ## Bluetooth * https://www.redpill-linpro.com/techblog/2021/05/31/better-bluetooth-headset-audio-with-msbc.html * https://web.archive.org/web/20210614103423/https://www.redpill-linpro.com/techblog/2021/05/31/better-bluetooth-headset-audio-with-msbc.html
