I am unable to get any sound from the SOMO 14D.
I am using a SO 14D in stand alone (key mode), with the following configuration:
3.36VDC supply (rated at 500mA)
250uF capacitor across the power rails
8 ohm 0.5 or 0.25 watt speaker wired to speaker output
Breakout of various control buttons to ground
Using the example files, the BUSY indicator comes on during playing, but i hear nothing (other than a very very faint pop when it starts playing). I have tried resetting (which causes the LED i have hooked up to BUSY to come on for a short while), next, play, etc. with no luck.
I also have connected an O scope to both AUDIO and SPK+/- and every time it plays, the output is completely flat.
I am using the example ad4 files provided on a 2GB SD card formatted with FAT16 on a windows XP computer.
Any ideas on what I could try next?
