linux mint – PulseAudio Audio Devices Disappear After Reboot, Or Maybe Not
Half the time after a reboot the USB Behringer U-Control UCA202 does not show as an input or output device in the PulseAudio Volume Control.
The system is running Linux Mint Cinnamon 19.3. The UCA202 is Device-2:
Audio: Device-1: Intel driver: snd_hda_intel v: kernel bus ID: 00:1f.3 chip ID: 8086:02c8
Device-2: Texas Instruments PCM2902 Audio Codec type: USB
driver: hid-generic,snd-usb-audio,usbhid bus ID: 1-3:36 chip ID: 08bb:2902
The pactl list outputs:
pactl list short sources
0 alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo module-alsa-card.c s16le 2ch 44100Hz RUNNING
2 bluez_sink.C0_7A_CC_02_00_F5.a2dp_sink.monitor module-bluez5-device.c s16le 2ch 44100Hz RUNNING
pactl list short sinks
1 bluez_sink.C0_7A_CC_02_00_F5.a2dp_sink module-bluez5-device.c s16le 2ch 44100Hz RUNNING
I would guess that a device scan is failing – don’t have any idea to fix this.
