Choppy sound on Twinkle Softphone on Ubuntu Linux - Solved

Posted At : November 6, 2008 9:53 PM 1 Comments

I just reinstalled my system with the latest Ubuntu 8.10 x64 and one of the apps I use regularly for testing and developing Asterisk applications is Twinkle, which is a great VOIP softphone.

It works great, but when I tried it in my new install the sound was all choppy, i.e. I would get every half of each second of the audio.

A bit of fiddling about with the settings and I got it solved. Posting it here so when I forget about it and run into the same problem again I'll know how to fix it.

The solutions is as simple as:

  • From the menu select Edit -> System Settings.
  • Select Audio on the left
  • Change the audio devices to use the most approriate device that is NOT "ALSA: default: Default Device" - in my case it was "ALSA: plughw:0,0: HDA Intel (AD193x Analog)"

I do like the very friendly naming scheme for devices :-) Hope it helps, Mark

Well, this makes Twinkle work, but you can't have anything else running that uses sound because then the audio is blocked. Twinkle will give an errormessage if a call comes in and for example Amarok is running.
