In an attempt to improve audio quality (when volume is maxed out the audio takes on an irritating quality), I have plugged in an external speaker thinking the larger speaker will sound better than the tiny internal speaker. But because the earphone jack is “dummied down” in an effort to protect against injuring our ear drums when using head phones or ear buds, I loose maximum volume. Is there a work-around to allow for disabling the restriction placed on the earphone jack? I know I could use an amplified speaker but that adds a needed power supply, (a battery) to the mix, reducing the portability aspects of the handheld SDS100. Any suggestions?
