JBL USB easily used as output device, but no input device is detected

Hi,
I’m trying to really rely on my Manjaro set up as my main computer, however I am not able to get my microphone to work.
I’ve looked into this but can’t really find a solution yet.
I must admit I do not really understand how to tell what is wrong, but to summarize:

I have a set of JBL 600 headphones. The headphones operate from a USB that acts as a wireless connector. I don’t think this is a Bluetooth device, but again I am not 100% sure. As a set of headphones they work great, I can use pulseaudio to select them, and they work great.

The problem arises when I want to use the built in microphone. I cannot find any input devices on my system, even though I know there is a microphone built in. Honestly I’m just confused.

any help would be appreciated, in finding a solution to this.

It is a Bluetooth (v4.1) headset with a build in mic.

Are you sure your using HSP/HFP mode (mic enabled) and not A2DP (mic disabled)?

Ok I’m looking into the difference between HSP/HFP mode and A2DP
in the mean time this is my output for

thought I should include this retroactively.

Euh…

Oke do you have a Tune600 or an Quantum600?
The reason I ask is that a tune 600 has an mic build in (hence your saying “I know there is a microphone built in”) the quantum 600 has a normal headset mic. The first is BT the second is 2.4Ghz Wireless model.

this is a long shot but perhaps this works

pacmd load-module module-zeroconf-discover

If it does not, what are the outputs of:

arecord -l

and

sudo lsusb -vd 0ecb:203c

I had the exact same problem with my JBL TUNE600BTNC and this worked for me:

Finally I am able to switch from A2DP to HSP/HFP
Thanks! :green_heart:

Sorry I have not been able to test this I will when I get home today and edit this post.
It is a quantum600 which I guess means that it is the 2.4GHz wireless model.

Ok

I ran

pacmd load-module module-zeroconf-discover

but don’t have any thing different when I look in pulse audio.
i.e. no audio input options, no recording devices detected.
is that what I am supposed to be looking for??

what is it I am supposed to be looking for??

Yes

Lines like:

bDescriptorSubtype 2 (INPUT_TERMINAL)

and with that the terminaltype.
I was hoping to see Microphone and not only USB Streaming or Headset

Since arecord -l shows the quantum600 there is an input device.

Oke first check if you did not mute the mic on your headset.
Second check in alsamixer (F4 to get input then F6 to get all cards and select the Q600) if there is nothing muted and if possible set the slider to 70

Next i wonder if you get a sampelrate output if you do

arecord -f dat -r 60000 -D hw:2,0 -d 5 test.wav

Same issue here with JBL Quantum 800 (via USB 2.4 GHz Wireless).
In PulseAudio: the headset is there as Input Monitor but not as hardware input device.

if i run

arecord -f dat -r 60000 -D hw:3,0 -d 5 test.wav

I get: arecord: main:830: audio open error: No such file or directory

I looked at

bDiscriptorSubtype 2 (INPUT_TERMINAL) 

but didn’t see anything that looked related to a microphone.

alsamixer was already set up as you described. I didn’t see anything muted there. I remember looking through there before in my searches.

As for the microphone being muted. It has a positional toggle that automatically mutes it if it is folded up, and activates it when it folds down. I can hear my self talking into it when it is folded down, but don’t have anything on the computer that indicates it is sending any sound data.

arecord -f dat -r 60000 -D hw:2,0 -d 5 test.wav

yeilds and error:

arecord: main:830: audio open error: No such file or directory

Oke since it seems your getting a loopback since your saying you hear yourself talking.

First make sure your card is in Duplex mode (advanced tab in pavucontrol)
If it has no Duplex mode what are the mode options for your card?

Then in alsamixer

F3 to make sure your in output
F6 to find card and select

Next mute all mic and disable loopback (if there is any).

OK, I don’t see anything labeled duplex under the advanced tab.
I am able to access this advanced tab for the device under “Output Devices” however, under the “Input Devices” tab the Advanced tab is greyed out and unusable.

Under the Advanced tab accessible from the “Output Devices” tab I have a series of check boxes labeled:
PCM,
AC3,
EAC3
DTS
MPEG
AAC
and then an input bar for Latency offset.

In alsamixer I do not have any loopback options,
PCM = 00 and PCM1=00
are the only options following F3 and then selecting my card from F6.

So sorry meant the configuration tab in pavucontrol.
Was a bit late last night.

I hope you selected the Q600 there. If there where no mic or loopback settings thats fine

Haha, No worries. I looked under the configuration tab as well but for “quantum 600” the only options are:

-Analog Stereo Input
-Digital Sereo (IEC958) Output
-Off

I did select the Q600 in the alsamixer.

According to JBL-Support: JBL has confirmed that the mic is currently not running under Linux (Quantum 800), regardless of USB wireless, Bluetooth or AUX (wired).

If a Linux compatibility update will be available is currently unclear.

Probably it’s the same for Quantum 600.

Dang,
That is disappointing for sure. I had talked to their support a while ago but they told me to look into the connection on my end.
Well I guess I’ll have to find another way to use a mic for the time being.

Thanks everyone for your help.
