I plan to buy an archos 43 IT. The only point that prevent me to buy it is that it is not possible to connect an external DAC to the usb port of the Archos 43 (as the Fiio E10). The goal is to bypass the internal DAC and use a hifi DAC to play music at home.
This feature is apparently not enabled in the default Android kernel (sorry, as a new member, I can't post external links, but it's in position 23 of the user's requests for android 4.0)
Archos recently implemented this feature in the last firmwares of the Gen9 Internet Tablet, but I doubt they foresee this for the Gen8. I thought that this could be have been implemented in Urukdroid, but a search in this forum and in google lets me think that this is not the case.
Is this possible that this feature would be implemented in a future release of urukdroid ? Otherwise, I can always try to compile my own kernel, but this is another story...
PS: Some info from linux-usb.org (sorry, I can't post links, so I quote):
USB Audio Support
USB audio systems such as speakers normally comply with the USB audio class specification. If your audio device does not comply with the specification, it will not work with Linux at this time.
You need to turn on the Sound card support kernel option, which is in the Sound section. You will then be able to turn on the USB Audio support option in the normal USB section.
If you elected to use modules, you need to load the module called audio.o.
You can test your installation by dumping some random data out to the audio interface, using a command like cat /bin/bash > /dev/dsp. USB audio is integrated into the normal Linux sound architecture, and most tools should work fine with USB speakers. See the Sound HOWTO for more details and suggestions.
