No sound output from DAC on Pi Model B

I have an old Raspberry Pi Model B and read your article "Re-use your old Raspberry Pi as a music player". So I installed Volumio (which is fabulous) and ordered a HiFiBerry phone version DAC on Saturday. It arrived in the UK just three days later on Tuesday, which was great.

Problem is, while Volumio was working just fine with the standard audio output on the Pi it won't work with the DAC. Volumio recognises the card and gives me the HiFiBerry options for the i2S driver and the audio output, but whatever I try I can't get the actual music to come out of the phone output.

Is it possible that my soldering was not good enough for the audio signal even though the card is being recognised? I have a multimeter but don't know which continuity points to test. Can you advise on that?

Many thanks for any help. Volumio is transforming the way I listen to my music and I'm keen to build a multi-room setup. My next order will be the HiFiBerry Amp if I can just get this first one working and it sounds as good as I'm expecting.

If it's of any help, listed below is the output from aplay -L.

Regards,
Paul
