What bus is used to communicate with the sound card? The obvious candidate is USB, but the Pi's USB bandwidth is limited and I don't recall whether USB is available on the pin headers.
I love the fact that a whole ecosystem has appeared around patching up the holes in the Pi's architecture[1]. Unfortunately by the time you've purchased them all, you probably could have bought a BeagleBoard instead. [1] The built in codec and filtering is absolutely horrible making it pretty useless for audio applications.
usually when people do [1] or something like that it's to a link. to my ear the audio out of the pi's hdmi port is perfectly fine. i think the DAC used in the RCA jack is probably not very good. I would pay for a HDMI audio to DAC adapter rather than $33 for another soundcard that just works with the pi.

Nice. PI's built in audio processing is extremely crappy and the analog 3.5mm output is almost unusable for music.
How can I actually hear this? I am no audiophile, but I can't notice any audio problems with my Pi.
For example, the Cowon S9 audio player was supposedly designed for high output quality, with a pile of DSP presets for EQ etc. With the e5c's you can really hear the poor quality processing of the EQ, especially on reverb tails. Have to turn the EQ off completely to eliminate them.

apparently the DAC for the RCA out is 11bit - but I can't really find any definitive proof of that.
I might have a go tonight.
Link: http://uk.farnell.com/wolfson-microelectronics/wolfson-audio... It's disappointing that this doesn't support v1.0 boards. I hadn't realised that RPis had been fragmented like that.
It's definitely a shame that things are fragmented, I was considering adding audio to my old Pi. But at least they're cheap enough to justify buying a second one :-)

I find quality in-ear headphones extremely revealing of poor quality output. Shure e5c, to pick an older set that I own, are especially unforgiving of noisy output stages and cross-coupled interference. The additional acoustic isolation really helps your brain focus on the audio by cutting out the masking effects of environmental noise. This isn't always a good thing. For example, the Cowon S9 audio player was suppos…

By EQ you are referring to equalizer? So if I don't use EQ on RPi (which I don't), I'm good? Is there some particular audio clip which I can sense the crappiness when listening to?
To hear these sorts of things, listen for reverb tails on drum hits, high frequency percussion like cymbals, high-hats, solo human voice (we're quite good at hearing unnatural artefacts in voices) - that sort of thing. Beware it has to be good quality source material to start with though!
