Hi,
I received my Bifrost/Uber usb two days ago. After few tests I finaly handle to make it works fine on my debian (minimal install).
Perhaps it can help someone so I explain you how what I do to make it run.
First I remove all my audio packages (both pulse and alsa) with purge and autoremove.
Then, I install alsa (alsa-base ; alsa-utils ; alsa-oss (?) ; alsamixergui ; libasound2 )
After that I create a ~.asoundrc file with :
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
You can find the card number with command : aplay -l
I'm using MusicOnConsole (moc)for listenning my music, its very light, simple and it look great after a little color configuration.
So in the ~./moc/config file I uncomment the line : Allow24bitOutput and put the value at yes
Before doing that the bifrost always being in Altset 1 with Format S16_LE (you can see that when taping : cat /proc/asound/card1/stream0 when playing music) and my 24/192 files sounds very bad.
And its all.
So I think I am now in "bitperfect" mode :
- Can't move the volume in alsamixer or moc (always at 00)
- Can't play 2 sounds flow at the same time (per example when running moc I can't play song with youtube)
- No resampling ( I'm not 100% sure about that but the command cat /proc/asound/card1/stream0 always gives me the good sample rate and the sample option was quoted in moc...)
The bifrost sounds very great compare to my dx50 : more lively soud, more impact, a wider soundstage... Very happy with it.
Enjoy !
