http://bugzilla.opensuse.org/show_bug.cgi?id=1172412 Bug ID: 1172412 Summary: alsa: Kingston HyperX Quadcast USB audio output silent at low volume Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Factory Status: NEW Severity: Normal Priority: P5 - None Component: Sound Assignee: tiwai@suse.com Reporter: tyson@tyson.me QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 838432 --> http://bugzilla.opensuse.org/attachment.cgi?id=838432&action=edit lsusb -v output I'm running Tumbleweed 20200528 with kernel 5.6.14. There is an issue with the Kingston HyperX QuadCast USB microphone + headphone interface (USB 0951:16df). The microphone works fine, but the headphone output only produces sound when the volume in KDE Plasma/ALSAmixer is set at 31% or higher. At 30% or below, there is no sound from the headphone interface. In Windows and macOS, audio output starts from 1%. I'm not sure whether this is the right place to report or if it should've gone upstream. It seems like this device may need a quirk entry in ALSA, but that's just a guess. I know this will be difficult to diagnose without direct access to the hardware, but am happy to provide more information or test any patches. I will attach alsa-info and lsusb -v output. -- You are receiving this mail because: You are on the CC list for the bug.
