Recently somebody asked me for mini PCs with audio output for stereo speakers, and I recommended something like MINIX NEO X6 with a dedicated 3.5mm audio jack, but I’ve just discovered USB sound cards with stereo output and microphone input are incredibly cheap, even less than $1 shipped on Aliexpress, and just above $1 on Ebay.

Yet it would be interesting to prospective buyers to find out if advertized features such as audio pass-though of 5.1 & 7.1 codec does work, and whether 4K output (listed and real), HDMI-CEC, 3D videos and other features not supported by my current Panasonic can work properly. It would also be fun for me to test these features. That’s why I’ve been thinking …
