Have finished wiring up my audio mod, updating to ER9X-772...but get no audio out I have programed the radio to PiSpkrVoice and programmed one voice safety switch to the AIL TX switch for testing.
Here is what I observe:
- Backlight switching via new interface cct works fine.
- If I turn the radio on and put my ear on the speaker I can just hear a burst of tones (not voice), pause, and then another burst of tone. This as the TX goes through Splashscreen then to Model display.
- If I activate my AIL switch I hear one burst of tone, putting switch back again gives another burst (I programmed "BOTH" option on safety switch).
- If I do all this with the SDcard out I hear nothing at all.
Many thanks, Argo.
