    I have an HTC Evo and a FiiO E7 headphone amp that I use to drive my headphones. I am looking for a way to output the audio from my phone to my amp without having to use the 3.5 mm jack. This is because the DAC in the FiiO is much better than the phone's DAC, thereby giving me much better quality sound.

    When using my computer, the process is very simple: I plug in the amp to the computer using a USB to mini-USB cable and then connect my headphones to the amp. The computer sees the amp as a plug and play external sound card, and it works perfectly.

    Is there any way to do this with my phone? I know that the iPods and iPhones support this through Apple's proprietary dock connector (I can do this with my iPod).

    To clarify: I want to use the mini-usb or mini-hdmi cable on my phone to output a digital audio signal to the mini USB jack on my amp/DAC. Also, the amp is battery powered, so as long as I can get the two devices talking, I don't need to worry about power.

    Thanks in advance for all the replies!

    I'll second this. I'd like to use a similar setup.

    I sure would like to talk about this more. Can this be done by rooting the EVO 4G? With the 8m camera I no longer carry a seperate phone, but the sound of the EVO is generally not up to my standards.

    well there are a few things that you can do with a rooted evo. there are a few roms that have sense 3.5 ported from another phone that has beats audio built in. also most roms have dsp manager now. this works kind of like an equalizer that has improved the sound quality from the evo.

    You will not be able to connect a USB DAC to your phone until ICS is available for your phone.
