Resurrecting this thread from the depths of Head Fi. I am planning on a USB DAC soon, and am looking for some bit perfect software to play FLAC files through. I ripped most of my music with Rhythmbox, which has worked well so far. It fixes a lot of the skips other rippers give me, and is WAY faster than EAC. Some of the tags are messed up, though. I have also been playing through Rhythmbox, but I'm only on onboard sound right now, so no idea how the quality compares. Stuff sounds great on my D2, though a couple tracks I have never had any issues with in the past had skips in them. I may have to find an alternate ripping utility.

Tags: I have been using Ex Falso for tagging all my classical music thus far. I do need to find an ncurses based tagging software that is keyboard efficient.
Have you tried MPD? Google the wiki. Makes a lot more sense to use MPD if you're going to be using a small silent machine. There is also a thread here that I started about using a single board computer ( a PC Engines ALIX) for a dedicated music server. Check it out.
I just have one PC. I use Linux as my general usage OS, and Windwos 7 RC for playing games. I just didn't want to have to use Windows for my music, or I would geto ut of the habit of Linux again.

Usually not, but it can be handy.

Or alsa?
If OSS4 supports all of your hardware, and you don't put your PC to sleep, you can use it instead of ALSA. ALSA by itself is a polished turd, but I like my S3 (FI: if mplayer crashes, and it's going out ALSA, I lose all sound output until a reboot, and cannot do a software reboot...but only w/ straight ALSA). ALSA should have been made cleaner and halfway robust, and hopefully it will die a painful death (as OSS4 gets made better).

How bout just stock pulseaudio on ubuntu with audacious? And what exactly is bit perfect anyways?
Pulse adds overhead, including high CPU usage when resampling, and still needs ALSA or OSS4 to talk to your hardware. Pulse is not a driver, but a sound server, that takes away the real handling of audio mixing from the driver, which in the case of ALSA, is a very good thing.
This guide is for Ubuntu 8.10, I don't know if it's valid for other dists.
To bypass the software mixer you need to use hw:X,0 as you output device (X being device number, hw:0,0 if you only have one audio device)
To confirm your playback mode use this command (card0 assuming you want to see info on audio device number 0):
sudo cat /proc/asound/card0/pcm0p/sub0/hw_params
Happy tinkering
Edit: to see your playback mode you have to have audio playing of cause.
Edit2: This is only valid for Ubuntu and variants there of, fx. Linux Mint, Xubuntu, Kubuntu.

this is not strictly correct.
a mixer at full gain (100%) will not touch the bits in any 'bad' way. no SRC happens in linux unless your card doesn't support the native SR being played. if you have a 44.1 able card you will never be resampled.
the gain will not change either, thru the mixer, if its left at 100%.
so, you can run 'no harm' mode even thru linux mixers. they're not 'forced src' boxes like windows often is.
I use mpd as the backend and usb audio as the 'driver'.

That sounds most reasonable. It was a long time since I tried dmixing, and since the majority of my music is 16/44.1, it could have benefits. But on the other hand, some of the 24/48 or /96 are nice too.

Linux' ffmpeg project is the ffdshow equivalent.
And the other much used encoder library is xine-lib. But in general you don't install codecs like you'd do in Windows. The apps link into the "codec packs" like ffmpeg and xine automatically.
