[Protux-support] error opening playback bus

[lila]

hello,

i've a problem with protux 0.20.2 on gentoo-2.4.25, using alsa-1.0.5a.

there's an error with the playback:


*** Error in int Bus::open(int, int, int, bool, float)
Invalid mode for bus ENS1371 - 1st OUT (hw:0,1) : 44100 Hz, 16 bits,
STEREO

*** Error in int Mixer::go(long long int, long long int)
PLAYBACK THREAD START : FAILED : None of required playback bus could be
open. Try changing bus out on the tracks, please


unfortunately i can't change the playback bus, i get "invalid playback
bus" on the lcd.
when run protux with "--d2" i get a lot of these:


[   Trying 22050 Hz STEREO 16 bits :  FAILED :
ERROR_BUS_DOES_NOT_SUPPORT_THIS_SAMPLE_RATE ]

|   |   |   |   [   Trying 48000 Hz STEREO 20 bits :  FAILED :
ERROR_BUS_DOES_NOT_SUPPORT_THIS_BIT_DEPTH ]


which is strange, there is usually no problem with 44100hz/16bit sound. is
there a way to solve this? ( i hope, because i'd really like to check this
software out, i love interface already!! )

thx in advance,
