The trouble of Sound Chip (or Card) in Ubuntu Part4 [Computer]
The error of Pulsaudio occurred and I could not solve the problem by using PulseAudio Manager. I could not find the combination of parameters' settings.
Meanwhile, the problem was solved by using the "Sound" panel of the "Setting" of Ubuntu.
In Ubuntu 13.10, unfortunately I could not save the setting in the "Sound" panel. I tried to mute the digital audio (S/PDIF) by checking the box for mute, but when closing the panel and reopening it, the check-box was cleared. So, the error of PulseAudio occurred again.
On the other hand, in Ubuntu 14.04, I could save the setting of the "Sound" panel by checking the check-box of mute. By turning off the digital audio, I could solve the problem.
I think that failure of turning off the digital audios in Ubuntu 13.10 is a bug. In Ubuntu 14.04, the bug is fixed, I believe.
