Audio Input Question (TRRS?)
Apparently the Tinker Board's 3.5 mm (1/8") audio jack is Tip-Ring-Ring-Sleeve (TRRS) to accommodate headset-mic combos.  I just need to pipe audio IN to the device.  The schematic is unclear (to me); is the input on Ring 2?  If not, which is the input?

I've been foolishly trying to send audio in via a standard TRS "aux" cable!

On a side note, I also tried a USB sound card with a dedicated line in (a "CM106 Like"); it works, but the audio is distorted and filled with crackly digital nastiness.  At least that's better than the cheapie USB dongles, from which I get...nothing.

Thumbs Up 
Well, it took a bit of experimenting, but I finally have audio going into the Tinker Board!  One of the challenges was, the TRRS plug I was working with had a case that was too wide for the plug to seat properly when the board was in its case.  A slim-line plug helped solve that problem; now I have a Tip-Ring-Sleeve (standard stereo "aux" cord) connector going through a short cable to the Tip-Ring-Ring-Sleeve the Tinker needs.  Since the Tinker Board can only take mono in, I ended up using just one channel.

So, now I have my Tinker Board working as an Icecast streaming client using Darkice.

Will it harm if I will use a TRS to get the audio out for an ampli mono ?
Light blue words might be a link. Have you try to click on them? Big Grin
