Hello ASR members this is my first post and I really hope to become more active in here as my audiophile quest continues.
I recently bought a DoukAudio M1 Pro bluetooth amp/dac, and when I connect to my JBL HLS Center speaker, no sound comes out. I have used this same speaker with my SMSL 50 and I know the problem isnt the speaker, or even the banana clip/wires im using. I took pictures of my set up with the M1, and also opened up the inside to get some good pictures of the inner components.
The M1 powers on fine, and is able to pair the bluetooth via my iphone and Fiio M15 without issue with the BT finding my devices (shows up right on my phone detected BT devices and it shows up quickly) however NO SOUND comes out of the speakers.
Im wondering if its something im doing wrong, or if the unit is faulty. The power supply seems legit, but I'll add that when I plug the power adapter into the device, there is a minor electric spark noise (without any sparks).
I also tried to add my SMSL 50 into the mix as a pre amp, and daisy chained the cables from the SMSL to the speaker outputs of the M1 Pro, but nothing, still no sound. Im wondering if this was a soldering issue, or maybe way too much glue on the copper coils inside, or something maybe in the pictures attached that Im not privvy enough to know of due to my clearly lacking electronic skills. I do have a brand new multimeter from Harbor Frieght, its a cheap $5 one, but I have no idea how to use it or apply it to see if the speaker outputs on the M1 have any current running through them.
Thanks in advance for your help, tips, advice and participation in helping me figure this out.
