I've submitted an upstream MR here based on the OP's fix with some slight edits based on my tseting: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/286

As a result they also need a special profile. But there's another complication. They also have hardware HRTF that requires no special driver logic; instead, the "everything else" output pretends to be 7.1, and simply applies the HRTF to the streams sent by the host. However, the channel mappings picked up by ALSA are wrong -- the rear speakers and center/LFE are swapped. I know, technically this is two bugs, but they have the same fix which is impractical to separate. I'm attaching a "sennheiser-gsx.conf" based on the Arctis 7 profile that both corrects the channel mapping and exposes both output subdevices. A simple udev rule seals the deal: ATTRS{idVendor}=="1395", ATTRS{idProduct}=="005e", ENV{PULSE_PROFILE_SET}="sennheiser-gsx.conf" ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: pulseaudio 1:11.1-1ubuntu7.2 ProcVersionSignature: Ubuntu 4.18.0-16.17~18.04.1-generic 4.18.20 Uname: Linux 4.18.0-16-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC3: roothorick 7548 F.... pulseaudio /dev/snd/controlC2: roothorick 7548 F.... pulseaudio /dev/snd/controlC0: roothorick 7548 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Sat Mar 23 23:09:21 2019 InstallationDate: Installed on 2018-09-12 (193 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: pulseaudio UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 08/07/2014 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 2004 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: H87M-E dmi.board.vendor: ASUSTeK COMPUTER INC. dmi.board.version: Rev X.0x dmi.chassis.asset.tag: Asset-1234567890 dmi.chassis.type: 3 dmi.chassis.vendor: Chassis Manufacture dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr2004:bd08/07/2014:svnASUS:pnAllSeries:pvrSystemVersion:rvnASUSTeKCOMPUTERINC.:rnH87M-E:rvrRevX.0x:cvnChassisManufacture:ct3:cvrChassisVersion: dmi.product.family: ASUS MB dmi.product.name: All Series dmi.product.sku: All dmi.product.version: System Version dmi.sys.vendor: ASUS modified.conffile..etc.pulse.daemon.conf: [modified] modified.conffile..etc.pulse.default.pa: [modified] mtime.conffile..etc.pulse.daemon.conf: 2019-03-23T20:51:33.488207 mtime.conffile..etc.pulse.default.pa: 2019-03-23T23:03:49.029912 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1821494/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
