Amplifying Audio From A Iotiny

Im using the soundboard exb to play audio files but they are very faint.  Is there a way to add an amplifier like on the ezb?  I couldn't find a seperate audio out other than the speaker plug.   The default voice from the IoTiny sound good but not my audio files which are mp3,  i amplified the files in Audacity but they are still faint.

Thanks Jeremie for the idea of soldering to the left side of C11 to run audio to a separate  amp. This has at last given me good sound from the IoTiny.

When editing any files, use normalization in your editor.

Also, the ARC soundboard editor has a normalize feature built in. Use it to normalize your audio files in the soundboard after they’ve been imported

It’s not documented in the manual for the soundboard, but here’s the option circled

Interesting on soldering to C11 for good sound...I have a question about where the data specs say 3.3v --5 volt signal out tolerant. would my ultrasonic sonar that runs between 4-5 volts be too much current draw from signal output? I know I was advised never to do that on EZB4

Edit-----Oh okay I see now that is only 5volt input not output only 3.3v.
