Headphone audio on Dell Latitude E7440

techiechap

Hi,
I review various OS's for my channel and have been looking to post a review on NetBSD since most of my BSD reviews have been on FreeBSD. I've installed NetBSD 9.3 on my Dell Latitude and have tried XFCE and LXDE. NetBSD has detected most hardware including the FullHD display which was great since I am used to having to play around to the get the correct graphics drivers working.

However I am having issues with the headphone jack. This works fine on other OS's including FreeBSD and NomadBSD however whilst Youtube audio in Firefox works fine using the built-in speakers when I plug in the headphones I get crackling and then audio stops working on both speakers and no audio on headphones.

I didn't want to post a bug report since it may be because I am a newbie to NetBSD and am just not getting it 🙂

I have read through the audio page in the NetBSD manual and looked into mixerctl however no joy so far.

Here is the output from audiocfg
localhost$ audiocfg list

( ) ac3 16/16, 2ch, { 32000, 44100, 48000, 88200, 96000, 192000 }

Here is my dmesg audio output if that helps. Note I also have tried a USB Jabra speaker device but that doesn't seem to work either. You will see that in the output below.

Any help much appreciated. Thanks

uname -a ? Are you willing to try a daily 10_BETA build?

Hi thanks for the reply yes absolutely. I'll give it a go and post back.

Let's hope it's better these days 😉

@techiechap As for binary packages for 10, you have two options:
https://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/10.0_2022Q4/All

https://pkgsrc.smartos.org/packages/NetBSD/trunk/x86_64/All

Hi pin,
Thank you for your help. So I've managed to install NetBSD 10 on my Dell using the legacy BIOS installer.

All has gone fairly smoothly.

When starting up my Dell Latitude E7440 there is a crackle from the headphone jack if I have headphones plugged in. Headphone audio still did not work through the jack however once I had set the default audio controller I could get audio through the built-in speakers.

netbsd10$ audiocfg list

( ) ac3 16/16, 2ch, { 32000, 44100, 48000, 88200, 96000, 192000 }

As you can see the default picked up this time was the HDMI/Display port. I imagine that if my monitor had speakers it would of probably work. However I decided to try my Jabra USB speaker.

Now in NetBSD 10 it seems to detect correctly!

netbsd10# audiocfg list

( ) ac3 16/16, 2ch, { 32000, 44100, 48000, 88200, 96000, 192000 }

And finally when I switched my default audio device to 1 (USB)
netbsd10# audiocfg default 1
setting default audio device to audio2

Plugged my headphones into the Jabra I finally get headphone audio in firefox!

So yes audio has improved. However the headphone jack issue is still a bit odd given I almost rage quit yesterday installed FreeBSD on the laptop and everything including headphone was working again. However after a sleep I thought I would persist with NetBSD and happy to report back USB audio at least is working a lot better in 10.

techiechap However the headphone jack issue is still a bit odd

Can you post the output of these commands?

hdaudioctl list
hdaudioctl show n1 n2

Run them as root, and for n1 and n2 put in the codecid and nid from the list command. No need to show the HDMI device.
