Issue with sound on certified Dell Inspiron 7537

Hi,
please specify your kernel version and the version of your Ubuntu, you can run "lsb_release -a" and "uname -a" command from your terminal to get these information.
Thanks

Kernel version is 3.16.0-31-generic on Ubuntu 14.04.2 LTS (64 bit).

Of course it's not solved yet, I probably hit the wrong button for replying.

Hi,

I tried to reproduce this on a 7537 we certified before (with 14.04.1, 3.13 kernel) [1].
Internal speaker is working as expected on both 14.04.2 stock image (3.16.0-30 kernel), and after running upgrade (3.16.0-31 kernel)

As your hardware configuration may be different from the 7537 we have certified here, I will suggest you to check if it's a hardware failure, if it's not, please open a bug with "ubuntu-bug linux" for this.

Thanks

It is definitely not a hardware issue since speakers work on Windows.
I was finally able to get speakers to work by adding "snd-hda-intel" the file "/etc/modules" and doing "ldconfig". I will reopen the issue if this happens again.
Thank you!

BTW
the codec on this system is ALC283, which is obviously different from the one that you reported.

Is it possible that Dell made some hardware changes after the certification took place? I bought the laptop mid-October 2013.

Cool, thanks for sharing the solution

more update for ALC3223 and ALC283, they're the same, quote from comment #2, bug 1284432

+ { 0x10ec0283, 0x1028, 0, "ALC3223" },

seem rename as ALC3223 for DELL alc283

Yes I think it's possible that Dell changed their hardware, another possibility is that this model may have some variants.

After looking into bug 1327007 that I linked here, the alsa-info attachment indicates that it's runnig on ALC3223, instead of ALC283, I think this needs to be investigated.

Please let me know what I can do to help.

I just rebooted into Ubuntu after a few days, and speakers aren't working again.

Can you open a bug in lanchpad for this issue, so we can debug further? A bug can be opened by running the following from a terminal:

ubuntu-bug linux
