--- Comment #9 from Stéphane <mathojojo at gmail.com> ---
Thank you for trying to help me.

I don't understand what I should do. I would just like to have front speackers
(2.0) not 2.1.

I remember that the stereo profile was available some years ago (maybe 2 or 3
years ago). It's probably a regression somewhere in USB Audio drivers (at last
for my device).

If you (or someone esle) know how I can create the missing profile for my use,
it would be nice.
Even more usefull, if someone could fix it in the drivers, or in pulseaudio
(I'm still surprised that aplay -L give me a simple front output :

front:CARD=Ultra,DEV=0
    Fast Track Ultra, USB Audio
    Front speakers
surround21:CARD=Ultra,DEV=0
    Fast Track Ultra, USB Audio
    2.1 Surround output to Front and Subwoofer speakers
surround40:CARD=Ultra,DEV=0
    Fast Track Ultra, USB Audio
    4.0 Surround output to Front and Rear speakers
surround41:CARD=Ultra,DEV=0
    Fast Track Ultra, USB Audio
    4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=Ultra,DEV=0
    Fast Track Ultra, USB Audio
    5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=Ultra,DEV=0
    Fast Track Ultra, USB Audio
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=Ultra,DEV=0
    Fast Track Ultra, USB Audio
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
)

I was able to select "front:CARD=Ultra,DEV=0" in the squeezelight settings. And
that worked (But I had to suspend Pulseaudio first, as squeezelite directly
speack with ALSA).

I may not understand everything (that's even almost sure :) ) But why can I
select it for squeezelite alsa output, and it is not available and proposed by
pulseaudio ??

Thank you all.

Stephane
