USB Headset with (Built-In DAC/AMP) Not Recognized
Good day,
I am unable to consistently connect my headphones.
Combinations of un/re-plugging in the headphones and issuing of:
pulseaudio -kAnd they may eventually become operational.
Please see relevent dmesg output:

Re: USB Headset with (Built-In DAC/AMP) Not Recognized
Two things come to mind, as there seems to be a problem of opening the device with the default sampling rate of 44100, try changing the field to
default-sample-rate = 48000in your /etc/pulse/daemon.conf (don't forget to uncomment the line if it is commented) for initial testing you might also be able to use
speaker-test -Dhw:2,0 -r48000 -c2 #Alternate the -r parameter until you find a sample rate that works, and reflect that in the pulse config afterwardsAnother thing, that pops up occasionally is that the given USB port doesn't have enough power or/and is occupied by too many other devices, looking at the output of
sudo lsusb -vmight shed some more light onto that.
Btw, excellent first post, contains most of the outputs relevant to help attempt to resolve the issue

Re: USB Headset with (Built-In DAC/AMP) Not Recognized
Thank you very much V1del for your feedback and assistance.
I suspect that it may not be power related nor a sampling rate issue, but rather an initialization one specifcally with the handshake and passing over of devices between alsa and pulse.
Both sampling rates work with the speaker test:
$ speaker-test -Dhw:2,0 -r48000 -c2
speaker-test 1.1.2
Playback device is hw:2,0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 262144
Period size range from 48 to 131072
Using max buffer size 262144
Periods = 4
was set period_size = 65536
was set buffer_size = 262144
0 - Front Left
1 - Front Right
^CTime per period = 3.812795$ speaker-test -Dhw:2,0 -r44100 -c2
speaker-test 1.1.2
Playback device is hw:2,0
Stream parameters are 44100Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 44100Hz (requested 44100Hz)
Buffer size range from 90 to 262144
Period size range from 45 to 131072
Using max buffer size 262144
Periods = 4
was set period_size = 65536
was set buffer_size = 262144
0 - Front Left
1 - Front Right
^CTime per period = 3.919252However the device is not available under Pavucontrol screenshot and selectable but ineffective Gnome Volume Control Screenshot.
I suspect I'll need to manually set it as default / alternative-fallback device based on name, as the device / card number may change?

### Load several protocols

### Automatically restore the volume of streams and devices
load-module module-stream-restore
load-module module-device-restore
### Automatically restore the default sink/source when changed by the user
### during runtime
### NOTE: This should be loaded as early as possible so that subsequent modules
### that look up the default sink/source get the right value
load-module module-default-device-restore
### Automatically move streams to the default sink if the sink they are
### connected to dies, similar for sources
load-module module-rescue-streams
### Make sure we always have a sink around, even if it is a null sink.
load-module module-always-sink
### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle
### Enable positioned event sounds

Re: USB Headset with (Built-In DAC/AMP) Not Recognized
And speaker-test does provide sound output? You shouldn't have to load pulse modules manually usually. Is something occupying your headset for some reason? That would be very strange though, what does
sudo fuser -v /dev/snd/*give.

Re: USB Headset with (Built-In DAC/AMP) Not Recognized
Yes, the speaker-tests are audible when the headphones are not correctly recognised by pulse, and only for valid frequencies:
$ speaker-test -Diec958:Illuminated,0 -r48000 -c2
speaker-test 1.1.2
Playback device is iec958:Illuminated,0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 262144
Period size range from 48 to 131072
Using max buffer size 262144
Periods = 4
was set period_size = 65536
was set buffer_size = 262144
0 - Front Left
1 - Front Right

When correctly recognised by Pulse:
$ sudo fuser -v /dev/snd/*
USER PID ACCESS COMMAND
/dev/snd/controlC0: gdm 905 F.... pulseaudio
nuk3 24072 F.... pulseaudio
/dev/snd/controlC1: gdm 905 F.... pulseaudio

/dev/snd/pcmC2D0c: nuk3 24072 F...m pulseaudio
/dev/snd/pcmC2D0p: nuk3 24072 F...m pulseaudioWhen they have not been picked up by Pulse:
$ sudo fuser -v /dev/snd/*
USER PID ACCESS COMMAND

I know that this may seem anecdotal, but could it be related to the session / user fingerprint assigned to the device when I connect it? If i remove my user's pulse configuration:
$ rm -r .config/pulseThe number of un/replug and kill/re-start pulse 'seem' to be far fewer...
