Low maximum volume with Plantronics Blackwire 315.1
by Paul Menzel 21 Aug '25

21 Aug '25

Dear Linux folks, On the Intel Kaby Lake laptop Dell XPS 13 9360, using Debian sid/unstable with Debian sid/unstable and Linux 6.17.0-rc2-00053-gb19a97d57c15, connecting the USB headset Plantronics Blackwire 315.1, even turning the volume on the headset control (or GNOME, both are linked) to maximum, the volume is still very low. `pavucontrol` shows everything on 100 %. Is that a driver problem, or somehow a hardware property? I uploaded the files done by `/sbin/alsa-info` [1]. Kind regards, Paul [1]: https://alsa-project.org/db/?f=ccc9945a112e88c7b6bf29ecc072f05e0cb72f3f
