I actually use the HiFiBerry DAC+ card. It is a sound card but does not have an amplifier. I then run that through my home stereo amp. So you could use that little amp you have there with the DAC+ and should improve your sound.ptyo wrote: ↑Tue Dec 31, 2019 8:46 pmHmm.. Well It would appear to be the audio card of the raspberry pi. When i connected my PAM8403 to my laptop the sound is surprisingly good. No crackling or pop-ing noise etc.. So hi see everybody seems to be using the HifiBerry. Does it have a built in sound card? My concern is the small 8ohm 3 watt speakers in this old cabinet. Any particular links to HifiBerry's that people find easy to use?ptyo wrote: ↑Tue Dec 31, 2019 6:22 pmWell hooked up the PAM8403 and didn't smoke anything on my raspberry. So connections must be good.
I do have an unusual sound issue though. Regardless if I use HDMI audio or the 3.5 mm jack. When the Raspberry goes into sleep mode I hear crackling and popping through the speakers. I have already upgrade alsa from 1.1.3 to 1.1.7 but it didn't fix it. Anybody else have that issue and now the fix?
