As the title says, i get very low sound in ubuntu, and when i raise the volume, it sounds "cracked" In windows it works fine. I've got a Realtek ALC800 soundcard, intel ich6 controller. I have tried everything, from changing the alsamixer configuration to installing the newest alsa drivers, and changing that alsa modprobe conf thing. Any ideas?
In alsa some cards are not meant to be "maxed out" in volume. I would leave the mixers around 95% or so. If it is still quiet try moving some mixers and not others. This may or may not help you.
Try turning volume down in alsa a bit so it does not crackle and turn the volume up in the pulseaudio mixer to 130% or so. This may change with the alsamixer setting as well though.
You updated alsa drivers correct? Did you use a script method or the Ubuntu Alsa Backports package? I have had good results with the package myself.
If nothing else, report this as a bug. Especially if you figure out a solution. Refer to this documentation for further help: https://wiki.ubuntu.com/DebuggingSoundProblems
Sorry I could not be of more help, good luck! I know a tiny bit about sound so I can help you look into OSS or something as well (however that road I never went far down). Perhaps if all else fails give a look into this: https://help.ubuntu.com/community/OpenSound
