Topic: hardware (speaker)
I had a few hardware questions:
Does the chumby one come with two speaker driver chips (TPA6211A1DRB)? Is it possible to easily add a second speaker to get stereo audio output? Looking at the spec sheet for the chumby one and the TI chip it looks like a second resistor and capacitor could be added to create a band pass instead of a high pass filter to improve audio quality (not sure by how much but it's worth a shot). It would be a single ended version of figure 31 from the spec sheet (http://focus.ti.com/lit/ds/symlink/tpa6211a1.pdf) instead of figure 30.
Does the chumby one use the headphone detect to switch between mono and stereo audio output? If so then simply adding a second speaker wouldn't work and would require some software hacking as well.
Thank you chumby for making this project open source. I totally wasted my morning looking at schematics and spec sheets.
