[Bug 1248116] Re: [Gigabyte Z87X-UD3H] PulseAudio switch rapidly port making the sound horrible


This motherboard seems to have a flaky jack detection - when the
front HP is not present, the jack state quickly switches on and off.

This has been reported by three people in the bug, so I doubt it's
a user error this time.

  [Gigabyte Z87X-UD3H] PulseAudio switch rapidly port making the sound

Status in “linux” package in Ubuntu:
  In Progress

Bug description:
  I have a Realtek sound system integrated to the motherboard Gygabyte
  Z87X-UD3H (http://www.gigabyte.fr/products/product-
  page.aspx?pid=4481#sp) having problems on Ubuntu 13.10.

  The sound is jerky. When I open the "Volume control PulseAudio" I can
  see pulseaudio changing the audio output "Internal Audio Analogic
  Stereo". The port switch rapidly from "Analogic output" to "Analogic
  headphones" making a jerky sound. ta tA ta tA ta tA.

  Do you have a solution to this problem ?

  King regards
