pHAT DAC on PiZero no sound. Software vs hardware?


#1

Installed pHAT DAC using the simple setup approach. Press-on only at the moment - wanted to check all OK before soldering.

No sound.

Have run two tests:
lsmod
shows snd_soc_hifiberry_dac and snd_soc_bcm2835_i2s

asplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

Have tried various sound test approaches, but nothing emerges. (Power speaker connected over 3.5mm jack to line out).

As far as I can see, I’ve done everything correctly - the modules are all in place etc. The only thing I haven’t done is the soldering. Surely that can’t be it?

Thanks all

I would put my money on it being unsoldered - HATs/pHATs aren’t really designed to be used unsoldered, so any functionality you do get is pure luck.

Thanks major_tomm. If that seems to be the issue, I’ll give the soldering a go!
