Now that I have Skype installed on Ubuntu 13.04 I discovered that the various Skype sounds were distorted. It was almost like the sounds had some static mixed in with them. I thought it was probably just a problem with the new version of Skype, or the new sound drivers. However, I made a discovery that fixed the issue.
I tried the AlsaMixer fix, but it didn’t work. (A reboot simply resets the PCM to 100 again, and the sound is still crackly.) So it all came down to a simple file edit to get it fixed.
Edit the file /etc/pulse/default.pa using the command:
sudo gedit /etc/pulse/default.pa
Add the following to the end of the line shown:
So after adding “tsched=0” to the end of the line “load-module module-udev-detect” you will be all set. After a reboot the sounds is still good.
Enjoy! Hope it works for you.
Recently I was having a consistent problem with the sound on my Dell Inspiron 1720, which is running on Ubuntu Hardy Heron. It would consistently stop working all together, and I had a terrible time finding the cause of the problem. If I viewed a flash video on the web, the sound would die afterwards. If I listened to streaming Internet radio, the sound would die. If I received an emial or IM the sound would die.
Finally it dawned on me, and I am not sure why or how. But a few weeks prior I had been toying with a Bluetooth stereo headset and had turned on the Audio service in the Bluetooth manager on the services tab.
Problem fixed: I simply turned off the Audio service in the Bluetooth manager, and all is working normally again. However, if I ever need the Audio service I suppose it will break my sound.
I was having a sporadic problem with my headphone jack in my new Dell E1505 laptop that came pre-loaded with Ubuntu 7.04 (Feisty Fawn), using ALSA. The problem was that when I plugged in my headphones, sometimes they worked, and other times nothing happened. No sound from my headphones at all.
Here is how I fixed the sound in my Dell laptop…
