I've a Legato II (USB to SPDIF converter).  I've it plugged into my
Cubox and when I do a "squeezelite -l", I see the following:

default:CARD=Legato            - Legato, USB Audio - Default Audio
Device
sysdefault:CARD=Legato         - Legato, USB Audio - Default Audio
Device
front:CARD=Legato,DEV=0        - Legato, USB Audio - Front speakers
surround40:CARD=Legato,DEV=0   - Legato, USB Audio - 4.0 Surround
output to Front and Rear speakers
surround41:CARD=Legato,DEV=0   - Legato, USB Audio - 4.1 Surround
output to Front, Rear and Subwoofer speakers
surround50:CARD=Legato,DEV=0   - Legato, USB Audio - 5.0 Surround
output to Front, Center and Rear speakers
surround51:CARD=Legato,DEV=0   - Legato, USB Audio - 5.1 Surround
output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=Legato,DEV=0   - Legato, USB Audio - 7.1 Surround
output to Front, Center, Side, Rear and Woofer speakers
iec958:CARD=Legato,DEV=0       - Legato, USB Audio - IEC958 (S/PDIF)
Digital Audio Output
dmix:CARD=Legato,DEV=0         - Legato, USB Audio - Direct sample
mixing device
dsnoop:CARD=Legato,DEV=0       - Legato, USB Audio - Direct sample
snooping device
hw:CARD=Legato,DEV=0           - Legato, USB Audio - Direct hardware
device without any conversions
plughw:CARD=Legato,DEV=0       - Legato, USB Audio - Hardware device
with all software conversions

My first question is, why am I getting so many different output device
options?  Who is providing all these options?  ALSA?

I mostly use the output hw and plughw.  When comparing the sound on
playing CD rips, I found that the hw connection sounds a lot better,
with a lot more details in the music.

So my second question is, is it possible to do sample rate conversion
when the sample rate of the music file does not match the capability of
the player?  In my case, my player only does 44.1.  So if I play CD
rips, it should go straight thru' without conversion, but if I play
24/96, I want it to down sample to 44.1 so I can still listen to the
music.

If the conversion is initiated in squeezelite, I want to see the above
enhancement in the code.  Thanks.
