Re: [ts-7000] Re: Newbie question before buying TS-7xxx

Why use a TS7400 and not a Beagle- or Hawkboard, if you need multimedia capability? 

Just a thought.

Yes, I think I'll repost of my questions in separate mails so I don't scare readers away from such a long post again.

Okay, so no audio out of the box. That's good to know.

Thanks for answering the probably most important question I forgot to ask =). It seems xmms2 (which is in fact what I'm planning on using) does support MAD for decoding. Guess that makes me home free?

I think these TS-7xxx boards are the closest to what I'm looking for. Remember I need DIO and ADC too.

True. I had a look at the atom boards, but they're very expensive and don't offer the same amount of flash as the ARM boards. Besides, I'm not scared of cross-toolchains as I've been working with Linux on embedded ARM before. What scares me, though, is ported drivers for USB WIFI and USB audio. I've had bad experiences with the first, but since TS supply this, I guess it's a nobrainer. I just need a confirmed audio solution.
