I have a small "problem" with the 3.5mm jack in linux/Zorin. First of all i uses Zorin on a old full spec iMac (Late 2013), 32GiB ram, 256 GB SSD, Nivida MX780m.
Linux and Zorin works just fine, but not for the 3.5mm jack. Speakers works fine, Bluetooth headset works fine.
But when i plug in a headset into the 3.5 mm output, there is no sound. The headset is recognized, the icon changes, you can see that there is sound on the VU meter. But nothing comes out of the headset itself.
No headset works, have tried variants with audio controls on the cable and headsets without this function. Nothing works.
What's the deal here? How to fix this if possible?
Is the headset jack dual-purpose i.e. headphone/mic?
In terminal open
Hit [F5] to show all channels.
Unmute (hit M key) at any that show "MM" = muted, and increase volume level.
If you see [Auto-Mute], toggle to Disable*.
If you see [Loopback], toggle to Enable*.
'*for those two, have a play with the different Enable/Disable settings and see if anything works.
Gday @Emil As @zabadabadoo has asked, it maybe the type of connection on the headset.
On the pc does it have 2x 3.5mm jacks? 1x for headset & 1x for mic?
Here a photo of some variants of 3.5mm pin's,
The 4 section pins from memory was released on the Lenovo pc's & can also be used on most phones. i'm not sure about imac pc,
If you have the 2x 3.5mm jacks & use a 4 section 3.5mm jack you can cause damage to the pc.
Note: you can get adapters to convert 4 section to 3 section.
Sorry for my late answer. Yes it is.
No. There is only one 3.5mm jack. Mye BOSE xc25 looks like nr.3&4 jacks on your image. My Koss Porta Pro looks like jack nr.1
Non of theese gives out sound.
And there was no luck with alsamixer suggestion..
Sorry, if not try installing PulseAudio Volume Control & then follow the above,
This a old full spec iMac (late 2013), i7, 256GB SSD, 32GiB ram, nVidia mx780m gpu.
I use the iMac's built in bluetooth card. Only thing i can say is that the 3.5mm jack works perfect in MacOS. Is it probably a driver issue?
Ok with the headset plugged in first run terminal & update : "sudo apt update", after that restart pc. If no good then try to install pulseaudio via software or
"sudo apt install pavucontrol".
Also in pulse audio check in the configuration tab, that the output in set to Analogue Stereo Duplex.
Do you mean: mac os and Zorin os just works fine ( is this a dual boot set up )?
Yes. I did. Still no sound.
No it isn't. It's a clean install av Zorin Pro on this old iMac.
Have you looked at pulseaudio control?
did it show headset in "Output" ?
