Public bug reported: Please see https://askubuntu.com/posts/1236257 for most background. tl;dr: - The Rodecaster Pro is a USB audio standard compliant device - lsusb sees it, but alsa cannot use it - trying the exact same setup with a Scarlett 2i2 USB device works (with some caveats, see the mentioned post)
Somehow the Rodecaster is ignored by Alsa. I am more than happy to help debug. Alsa info is at http://alsa-project.org/db/?f=94fd609fa23912ab0a39b67676a026fd163f3f3b and also attached. nils@blackbox:~/tmp/soundtest$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Generic_1 [HD-Audio Generic], device 0: ALC887-VD Analog [ALC887-VD Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Generic_1 [HD-Audio Generic], device 1: ALC887-VD Digital [ALC887-VD Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: USB [Scarlett 2i2 USB], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 nils@blackbox:~/tmp/soundtest$ arecord --list-devices **** List of CAPTURE Hardware Devices **** card 0: Generic_1 [HD-Audio Generic], device 0: ALC887-VD Analog [ALC887-VD Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Generic_1 [HD-Audio Generic], device 2: ALC887-VD Alt Analog [ALC887-VD Alt Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: USB [Scarlett 2i2 USB], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 5.4.0-29.33-generic 5.4.30 Uname: Linux 5.4.0-29-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: nils 90077 F.... pulseaudio /dev/snd/controlC0: nils 90077 F.... pulseaudio /dev/snd/controlC1: nils 90077 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: KDE Date: Sat May 9 11:45:20 2020 EcryptfsInUse: Yes InstallationDate: Installed on 2016-08-23 (1354 days ago) InstallationMedia: Kubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AudioUsers: pulse Symptom_Card: Family 17h (Models 10h-1fh) HD Audio Controller - HD-Audio Generic Symptom_DevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: nils 90077 F.... pulseaudio /dev/snd/controlC0: nils 90077 F.... pulseaudio /dev/snd/controlC1: nils 90077 F.... pulseaudio Symptom_Jack: SPDIF Out, Internal Symptom_Type: Sound works for some users but not for others Title: [HDA-Intel - HD-Audio Generic, playback] sound not working for all users UpgradeStatus: Upgraded to focal on 2020-05-09 (0 days ago) dmi.bios.date: 10/14/2019 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 5222 dmi.board.asset.tag: Default string dmi.board.name: PRIME A320M-A dmi.board.vendor: ASUSTeK COMPUTER INC. dmi.board.version: Rev X.0x dmi.chassis.asset.tag: Default string dmi.chassis.type: 3 dmi.chassis.vendor: Default string dmi.chassis.version: Default string dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr5222:bd10/14/2019:svnSystemmanufacturer:pnSystemProductName:pvrSystemVersion:rvnASUSTeKCOMPUTERINC.:rnPRIMEA320M-A:rvrRevX.0x:cvnDefaultstring:ct3:cvrDefaultstring: dmi.product.family: To be filled by O.E.M. dmi.product.name: System Product Name dmi.product.sku: SKU dmi.product.version: System Version dmi.sys.vendor: System manufacturer mtime.conffile..etc.modprobe.d.alsa-base.conf: 2020-05-09T11:23:29.080704 ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal ** Attachment added: "alsa-info.txt.eWNOZAwySG" https://bugs.launchpad.net/bugs/1877726/+attachment/5368861/+files/alsa-info.txt.eWNOZAwySG -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877726 Title: [HDA-Intel - HD-Audio Generic, playback] USB sound with Rodecaster Pro not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1877726/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
