After playing with the sound in Windows XP a little, I found out that a) the sound card has automatic detection of plug-in, asking questions what I just plugged in. b) headphones had sound distortion from back and front socket, as if a large frequency area where silence via an equalizer, while both regular speakers from the socket in the back worked fine after giving the right answer to the plug-in detection dialog. I didn't investigate this sound problem via headphones in WinXp much further at this point of time.
On Ubuntu when sound exists, it is fine. Problem is that it disappears when changing volume while sound is playing. Additionally there comes no audio from one of the regular speakers when plugged in the back socket where it worked fine through both on Windows. But I do hear static noise out of it. Furthermore, after making the sound go away as described numerous time, I am able to bring the sound back only on one output device (regular speakers from back socket, or headphones from front socket) - changing the volume of headphones or PCM while no audio stream playing brings back one of the output sound devices. Changing the other channel out of headphones and PCM while no audio stream brings it back for the other. On Windows sound comes out of both always (although not always a clear sound from headphones) - i.e plugging something to the front socket (the convenience one together with mic and USB sockets) doesn't mechanically disable the back one. I don't understand anything out of this logic anymore... -- No sound after changing volume while playing sound on an Intel 82801G (AD1986A) https://launchpad.net/bugs/56203 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
