I'm going to go back to JPlay again and have a listen. But even that sounds different in it's various modes, ie River, Beach and Xtreme.

Nuuk, What music player are you using?

Have you checked that alsamixer is not resampling up to 48K (which is does by default)?

Outputting directly to the device should give you an improvement in the sound.

"aplay -l" (ell) will give you a list of your sound cards

DeadBeeF, for example displays the sample rate of the playing song, and you can then compare it to what's being output to the sound card with the following command

cat /proc/asound/card1/pcm0p/sub0/hw_params (card1 and sub0 should be replaced by the Card/subdevice of your chosen sound card in aplay -l).

Here's a little one liner for lazy typers
I call it "sr" (sample rate)

#!/bin/bash
# script to outout the audio sample rate from card1/0
# usage example: sr 0 1    (where 0 is your card of choice and 1 is the subdevice)

cat /proc/asound/card$1/pcm0p/sub$2/hw_params

mpd does not seem too hard to install on Rasbian

To have the audio installed http://mitchtech.net/raspberry-pi-audio/

Otherwise it seems there is a slacko version for ARM http://puppylinux.org/wikka/Puppi
but I do not see mpd or equivalent in the available packages

It's not... but it's Debian, not Slacko Puppy, which he was asking about..

There seem to be some issues with higher res files being played via the USB interface though.. 24/192 does not work(although there's not much content at that sample rate)

I'll have another go with Slacko when I get more time, and have a fiddle around. But it is finding the time in conjunction with reviewing all these damn USB devices that's the real problem!

Still stuck
*** In alsamixer set 00 with the key M on both play and capture. No change

*** This is what I get with PupSystemInfo, the Luckit board WaveIO is recognized it seems :

2. If no positive outcome from above or alsa-mixer returns and error, then try running 'alsa-info' and it will produce a text file and upload it for you, post a link or a copy of that text file here.

The File is joined Chris. Hope you can read it

Thanks for helping

I have had a quick look through it and can't see anything obviously wrong, as you've said, not muted and the asound.conf file references the card & device produced by aplay -l. I will have a more detailed look tonight when I get home again. Perhaps others will have a chance to look before I get back.
