Circuit Sword Lite - Audio Problems

Hello All,

A question for anyone if you have the time,

I have finished Kite's Circuit Sword Lite build, using the analog volume wheel, but I can't get the audio to work at all. The message I keep getting is

1v10: VolumeControl::init() - Failed to attach to default card!
1v10: AudioManager Error - Unable to open SDL audio: ALSA: Couldn't open audio device: No such file or directory

I have made sure the USB switch is on 'internal', I have tried updating the config.txt file to read 'dtparam=audio=on', and I have tried various combinations with the sound settings with the main menu. I have also re flashed the card with the CSL software v1.0.1. Everything works great except the audio, speaker and headphone jack.

I'm not sure how to run an audio test, I feel that might be helpful as well.

An update:

I ran the software test, and I got

USB AUDIO = [FAIL]
GPIO SHDW = [ON]

Another update:

A bad solder connection to the DP (red wire) for the usb conn was the problem. It is working! thanks to kite, wermy, hoolyhoo, helder, and all the community
