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. The features for the model above are listed as follows: Real USB Plug & Play Drive 2-channelsspeakers directly Support 3D positional sound and virtual 5.1 channels sound track Powered via USB port Digital Class-B power Amplifier inside Speaker Shifter – 5.1x earphone, 2 speaker virtual theater Software Value-added for Music: 27x Environmont Effects, 3x Environment sizes, 10-Band/Pre-set Equalizer […]

The main reason is that the AV receiver and TVs required to test this are rather expensive, and these are not something I really need personally, since I seldom watch movies myself, I purchased a new Full HD TV last year, and I don’t expect to access 4K content for a few more years. 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 […]
