Fixing sound in Dell Inspiron 11 3147

Correction
The alsa-base.conf file is not needed to get sound out of the speakers. So I don't know what caused the speakers to turn off or what caused them to turn back on. What ever it is, it seems to survive reboots.

Original Message:
I had trouble getting sound to come out of the speakers on my refurbished Dell 11 3147. The headphones worked fine and I could get the speakers to work in both Windows and Ubuntu. I ended up copying over the file /etc/modprobe.d/alsa-base.conf from Ubuntu and then it worked like a champ.

I've attached a zipped version of the file.

I'm not suggesting we include this file with MX-14.3. That's not my decision (thank goodness).

BTW, you might be able to find a good deal on this machine if you get the version with Windows 8 on it (not 8.1). It has a beautiful screen and great sound. It converts into a tablet like the Lenovo Yoga. The touchpad works well and the touchscreen works OOTB (but no screen rotation). Now that the sound is working, what I think are the biggest issues are no Ethernet connector and no Fn key to disable the touchpad. For me, these are both very minor. I needed to use nomodeset but that will change once you get a 3.17 kernel (or higher).

I'm still in the early honeymoon phase. PS: Please excuse the shaky handwriting.

I looked and I couldn't figure it out. I will have to use trial and error but probably not today.

I now wonder if it might help other people with sound issues. Arch discusses the use of an alsa-base.conf file.

There is also an alsa-base package in Debian that contains a shorter but similar alsa-base.conf file.

Certainly worth looking at for MX-15. Good finds.
