hello, please excuse the delay.
first of all i must report, that the abovementioned reply from grant diffey: "It sounds to me like you haven't set up the internal mixer of the ultra correctly this will sound bad." was actually right. after lots of guesswork i dug into alsamixer's "effect" faders and they were wrongly set because of, probably, both settings made under windows as well as certain inconsistency in card's setup between systems (i.e. the wrong linux setting wouldn't manifest itself under windows at the same time). so i'm marking it as "invalid". however, i believe this is a symptom of a serious problem. if the system is rendered unusable (at least to me) for over a year and there's no way to get clear solution (the above answer was too enigmatic to me), there seems to be a problem with the whole ecosystem. please comment on how similar cases can be solved effectively. now to answer above questions (i actually indirectly answered it before): the gnome/unity sound control lets me change balance, fade and bass, however balance and fade are illogically entangled (moving one may move the other). am i expected to do any tests regarding your "log" question? thank you for the support. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1186512 Title: [USB-Audio - Fast Track Ultra, playback] Playback problem Status in “alsa-driver” package in Ubuntu: Invalid Bug description: there's an artificial spatilization when using usb multichannel audio interface. in 12.10, in the "sound settings" window it did manifest itself as "analog surround 7.1" profile, which is inadequate (i have 2.0 setup) and it applies some bombastic fx (reverberation?) and virtual channels to the stereo. in 13.04 i don't see the "analog surround 7.1" label anymore. it also has no input. there's only this fake surround profile available. seemingly it tries to put all channels (with reverbs) into two physical channels if it detects it's a multichannel device. and it happened specifically since 12.10, cause with 12.04 i had no problem. 12.04 had no "analog surround" profile forced on it. there are some reverbed virtual channels (side l, side r and center) added to outputs 1 and 2 (why?), and controls for balance and "distance" are entangled (moving one moves the another). also i have NO analog surround 7.1 setup. there are no other options.
