[Sennheiser GSA-70] arecord lists USB sound card but cannot record: audio open error: No such file or directory

Hello!

I own a Sennheiser GSP-670 headset and until the recent firmware (both for headset and dongle) I was able to use it with my custom PulseAudio profile (link to the profile: GitHub - szszoke/sennheiser-gsp670-pulseaudio-profile: PulseAudio profile for the Sennheiser GSP 670 wireless gaming headset).

The headset has a stereo (Main) output for games and a mono input/output for communication (Communication).

Normally the following audio devices are detected when the dongle or the headset is plugged in to a USB port:

  1. Stereo playback device (Main output)
  2. Mono playback device (Communication output)
  3. Mono capture device (Communication input)

After some investigation I noticed a few things:

  1. The headset connected directly via USB was still working as before
  2. The USB device ID for the dongle changed
  3. The order of the USB endpoints for the Main and Communication devices were swapped

After updating the udev rules:

# /etc/udev/rules.d/91-pulseaudio-sennheiser-gsp670.rules
`ATTRS{idVendor}=="1395", ATTRS{idProduct}=="0300", ENV{PULSE_PROFILE_SET}="sennheiser-gsp670-usb-dongle-audio.conf"`

And creating a new PulseAudio profile set with the right device-strings, I was able to get the two playback devices working with ALSA and PulseAudio.

At this point the headset was fully working if connected via USB but I was not able to get a capture device when connected via the dongle.

arecord lists the device as expected:

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: E70 [EPOS GSA 70], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
...
  unrelated sound cards
...

But when I try to record the capture card from the dongle I get an error:

$ arecord -d 5 -f S16_LE -r 16000 --device="hw:0,0" rec.wav
arecord: main:830: audio open error: No such file or directory

Seems like the device is found but it is not at the same time?

Can someone help me debug this further?

Other things that I noticed:

  1. The dongle now can be used with a Nintendo Switch, this was not the case before the firmware update
  2. The headset connected directly via USB to a Nintendo Switch is still not working, the audio keeps playing on the console as if the headset would not be connected at all

I am thinking that in order to support the Nintendo Switch, the dongle needed to use some kind of non-standard implementation for USB audio and because of that a custom driver or a quirk will be needed on Linux.

Is the output of that command connected over USB or connected over Bluetooth?

Instead of:

what does

arecord rec.wav

do?

P.S. Please read this:

and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)

Is the output of that command connected over USB or connected over Bluetooth?

No Bluetooth device is used here.

The output that you see is when the wireless dongle that came with the headset is connected.

$ arecord rec.wav
Recording WAVE 'rec.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono

It goes on forever until I interrupt it via keyboard.

I have a few other sound cards connected to this system, some via USB and some are integrated with the motherboard.

I can record them via arecord if I use the --device flag.

Some extra stuff that I didn’t include before because it didn’t seem relevant:

System logs after I plug in the USB dongle:

The PulseAudio profile that I am currently using is in the new-dongle-firmware branch of my repository: GitHub - szszoke/sennheiser-gsp670-pulseaudio-profile at new-dongle-firmware

This is way over my head, mate.

Post the link to the output file that sudo alsa-info.sh generates and our resident audio expert will need to have a look @nikgnomic …

:sob:

I suggest you consider updating BIOS to ‘Improve system performance’
ROG Crosshair VIII Hero (WI-FI) | rog.asus.com

The arecord error is correct that there is no device hw:0,0 because HDMI device is shown as card 0 and does not have a capture subdevice
(a USB device would normally be blocked from taking card 0 status by ALSA to allow for HDMI and onboard audio)

The USB Device is now shown as Card 2, but the card number could change if the 3 USB devices are detected in a different order
I suggest you use the card alias name instead of the card number --device="hw:E70,0"

I also suggest add options -c 1 for the mono channel map and -t wav

arecord -d 5 -c 1 -f S16_LE -r 16000 --device="hw:E70,0" -t wav rec.wav

I had hoped that this device would support a better sample rate than 16000Hz but it doesn’t

I don’t know if updating the BIOS would help and I would rather not mess with that because there are some known stability issues with the newer revisions that cause systems to reboot randomly.

You won’t be using this headset for recording vocals, that is for sure! :smiley:

Unfortunately I am getting the same error.

$ arecord -d 5 -c 1 -f S16_LE -r 16000 --device="hw:E70,0" -t wav rec.wav
arecord: main:830: audio open error: No such file or directory

It’s weird that the card numbers reported by arecord are so inconsistent.

When I plug in the headset itself, it shows up as card 5:

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: Generic [HD-Audio Generic], device 0: ALC1220 Analog [ALC1220 Analog]

  Subdevice #0: subdevice #0
card 5: G670 [GSP 670], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I can record card 5 both by using an alias or specifying it explicitly:

$ arecord -d 5 -c 1 -f S16_LE -r 16000 --device="hw:G670,0" -t wav rec.wav
Recording WAVE 'rec.wav' : Signed 16 bit Little Endian, Rate 16000 Hz, Mono
