I just installed LMDE on my desktop for the first time. It was previously running ubuntu 10.10, and since last month, 12.04. On Ubuntu, Audio worked as I expected it to. Audio *quality* is absolutely fine on LMDE, the issue is that when I set the global volume, it gets reset by banshee (others too, but banshee is the one where I'm fiddling most often) whenever I adjust the volume there. It makes it difficult to manage the sound level, especially because the rate of increase/decrease is different on both, and there's a little bit of an offset. One will show mute while the other one still has 3-8% volume.
I can't really describe the behavior better than this. It simply seems that application volume control is crossed with global volume output or something, it's making it annoying to be honest. I'll have volume at one level, turn on banshee and it's quiet (because it's showing volume at near zero). The moment I touch it's volume lever, the speakers are about to explode. I really want LMDE to work, Ubuntu's unity interface just won't do it for me - It's why I held on to 10.10 for so long.
Has anyone ever experienced this behavior, and/or anyone have some tips on how I can improve this? I'm very comfortable fiddling with the system, I just never bothered tinkering with my OS because I just wanted something that worked, and until now it always did. However, right now I'm looking for any suggestions or alternatives to the default audio (pulseaudio it looks like) system LMDE uses. If someone could at least explain why it would work one way on Ubuntu, and differently on LMDE, it would certainly help me narrow down the scope of my problem I imagine.
My system is a mini-itx fully integrated board with an intel core2duo CPU. The board is a zotac gf9300-g-e, and the audio/video is powered by nvidia's mobile GF9300 chipset, I'm assuming this detail may prove helpful.
