Hello,

I've been using RaspyFi for about a month now – via headphone jack

Today I hooked up a Chord DAC hopping to be impressed, sadly I get no sound.
I've done a few tests to see if there is anything obvious.
1. Boot with USB – no sound.
2. Boot with jack and usb connected I get sound via the jack. So RaspyFi does not see a audio-USB??

I have not tried any of the USB fixes on the form as my problem is not poor sound.

Thanks for the quick reply.

Sound is at 100.
Over putty the Fn keys do not work for me, so cannot obtain system information.
Correction – change keyboard in putty to be VT100 and Fkeys work

That is sad.

If you want me to do anything this end – just ask.
I can use Linux a bit – edit files, execute commands, files to/from RaspyFi etc.
