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.
