Audio in TinySA Ultra #ultra #software #features


 

Hi,

I have a TinySA Ultra (SW version : tinySA4_v1.4-156-g4eb315d HW version: V0.4.5.1.1 (185) and I want to use its audio signal demodulation capabilities (FM/AM)
I have plugged the headphones into the audio jack and I don't hear any sound.
Should I take any additional action? (Settings, Firmware, etc.)

Thank you

Juanpao


 

So from my experience. The audio port can be picky on what jack you stick inside. And for some reason on my ultra, I cannot insert it all the way or the sound will not work. Just pull out the male slightly and it should work again. This was always the case with mine since day one. I am kind of tempted to solder and new audio port to see if it fixes the problem. Something tells me it's a problem with production considering I've seen videos with the jack inserted all the way and your having the same issue as I. It did not like my Bose headphones and did not like male headphones with microphones. Try to find cheap earbuds with 2 rings on the male jack.??


 

Requires a TRSS jack, the 4 way type to work reliably in my experience.

Trouble is few stores carry the TRRS jacks.?

Look at tinysa.org for the settings it is not as easy as just plugging in the headphones and expect audio.


 

TRSS.

As used in modern PC equipment, so any cheap headset will do.

Or cellphone mics / headphones , often supplied with the handset will do.

The one I threw in my Tiny SA Ultra box came from a 10 yr old cellphone.

Plenty of splitter cables about on ebay etc for a few bucks,and convert the TRSS
style socket output to a two way leaded connection so that you can plug in
normal mono/stereo phones / earbuds to them.

Any old stereo earbuds or headset can be plugged in directly.
Do NOT use mono phones as these will short the output
The cheaper the headset, the better it may work as the cheap versions often have a high impedance which better matches the tinySA output.

Thanks Erik.

I just found another pair of stereo earbuds that now work with
my Ultra.

I must have reached my previous conclusion whilst using some
"dud buds" ;-)
