        Sounds like the name is 'USB PnP Sound Device'.

          @mitu ROMs load, no errors in run command, when I run a test wav file the light on the usb sound card flashes yet I still have nothing coming out of the speaker (which was new)...never realised it would be so difficult to get some sound out of this thing! Should I just give up and play in silence? 😐

                    if you look at mono playback it appears to be off (mic) open alsamixer again use the leftt and right arrow keys to check if anything is muted or off also what is your sound.

                    edit:

                    Check if you have a ~/.asoundrc file in your user home directory; it will override settings in /etc/asound.conf

                      @grant2258 all was fine there.....would you believe out of curiosity I found out some really old headphones and the sound was blaring from them - apparently brand new speaker DOESNT work!! Thanks for all your help guys.
