I blog.

When you feel like you’re stacking up on notes-to-self on your mind, what’s the first thing you should do? Start a blog to put those on. And that’s what I did.

Apparently I created this blog in 2010, but it was more for personal matters than this, so I started over while keeping the same theme (which still looks cool) and domain.

Don’t expect regular or particularly long posts.

Linux, Intel HDA, VIA codec and headphones

Yesterday, I finally got around to setting up Debian 7 on my main system (with Intel High Definition Audio and a VIA VT1705 codec), but I ran into an issue where headphone jack detection didn’t work: audio comes out of the rear output normally, but as soon as anything is plugged into the front panel output, both outputs are disabled.

All solutions I could find relate to systems with Realtek codecs, which is not my case. Here’s what solved it on mine:

  1. Start alsamixer
  2. Scroll all the way to the right
  3. Select the “Smart 5.1” option
  4. Press . (period) to unmute it

hda_alsamixer

Despite this option being (oddly) named “Smart 5.1”, enabling it will make headphone jack detection work.
