Dell 5559 Audio Card

Asked by Paun Remus on 2016-04-22


I bought a Dell Inspiron 5000 Series (5559 to be precise) with a pre-installed Win 10 Home Edition on it. I erased the Windows OS and installed Ubuntu 14.04 LTS. The problem is that in a less than 2 weeks my audio card went from full functional to non-detectable.

I checked in BIOS and it is also not detected there. The problems started acting up after I connected the Dell laptop to a Smart TV using an HDMI cable.

Can someone please tell me if the audio card is configurable from BIOS or if the Ubuntu installation has slowly degraded the use of the audio card? Is there any solution to this problem?

Best regards,

This sounds like an update regression. It's better to check the system with Ubuntu 14.04 liveUSB, as you mentioned that the audio works at the very beginning.

From the BIOS setting, you should be able to find the "Audio" section under the "System Configuration" section. You can enable / disable the audio input and output there.

Hello Po-Hsu Lin,

I do not have the option to enable/disable the audio input/output in BIOS. You are correct about the update regression.

I reinstalled Windows 10, updated the BIOS to the latest version and the updated the audio card driver. Then I deleted Windows 10 and reinstalled Ubuntu 14.04 LTS. Now my audio card work. I forgot to mention that there is a buzzing sound that I can still hear from time to time.

I am now curious on how I could have done the BIOS and audio card update without reinstalling the operating systems. Do you have any suggestions?

If re-installing 14.04 works for you (without applying any updates), it's better to open a bug report for it, otherwise it's likely that you will hit this again after an update.
Please check the FAQ here for how to open a bug report, and the guide [1] for audio related bugs.
And a FYI, here is the BIOS setting page on a Dell Inspiron 5559 [2]

FAQ #2193: “XXXX is broken, I need to file a bug”.

Hi Pso-Hun Lin,

It started to act up again. The Audio In BIOS is turned on and it did not turn off so I am thinking that this issue appears after I perform updates. Many thank for your help.

thanks for confirming this, this must be a regression issue, please open a bug report with `ubuntu-bug linux` command in a terminal (Ctrl + Alt + t) with your audio-not-working system, and explain that this works before upgrade. (You might be asked to do some more tests)
You can link the bug number back here after the report has been filed.
