http://bugzilla.opensuse.org/show_bug.cgi?id=1190112 Bug ID: 1190112 Summary: Pulseaudio fails to initialize headset after system has been running for some time Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Sound Assignee: tiwai@suse.com Reporter: tobias@ep1.ruhr-uni-bochum.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I have several USB headsets, which are supported by the snd_usb_audio driver in the kernel and do work under Linux. They also work on my system if it is freshly booted and has not been running for a long time. After this, plugging in the headset causes this error in PulseAudio:
E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="2" name="usb-C-Media_Electronics_Inc._USB_Audio_Device-00" card_name="alsa_card.usb-C-Media_Electronics_Inc._USB_Audio_Device-00" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=no card_properties="module-udev-detect.discovered=1""): initialization failed. I: [pulseaudio] module-udev-detect.c: Card /devices/pci0000:00/0000:00:08.1/0000:05:00.3/usb1/1-1/1-1.3/1-1.3:1.0/sound/card2 (alsa_card.usb-C-Media_Electronics_Inc._USB_Audio_Device-00) failed to load module.
Trying to load module-alsa-card manually also results in an initialization error. But the headset can be put to work by loading module-alsa-source and module-alsa-sink manually:
pactl load-module module-alsa-source device=front:CARD=Device,DEV=0 namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes pactl load-module module-alsa-sink device=front:CARD=Device,DEV=0 namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes
The device name has been determined using `aplay -L` and `arecord -L`. But if the headset is initialized manually, the volume is reduced, which is somewhat OK for the speakers but makes the microphone more or less unusable. I'm running a fully updated openSUSE Leap 15.2, PulseAudio version is pulseaudio 13.0-rebootstrapped. -- You are receiving this mail because: You are on the CC list for the bug.
