O.K. This Asus M4A88T-1 Dlx is a home brew that was intended for JRiver but will now hold Linux. Is there a recommended Linux build for audio?

I'm Jealous.. nice package. Too bad you need a cpu fan (I've had something in the works using a fanless Atom board..)

MPD (music player daemon ) with the latest ALSA is the easiest way to the best sound (baring the tweaks I mentioed). The MPD-Pup Distro is the quickest/easiest way to get things up and running, using PuppyLinux prepackaged with MPD. Less easy, but a good way to go if you want to learn a bit more is VoyageMPD, which is a stripped down version of Debian designed to run on small embedded X86 boxes.. I was running it with my Squeezebox with the OS running off flash, with the DB and music on a HD..

There is lots of great info on the PC-source forum here, and if you are interested, lots of reading material about setting up VoyageMPD on a lower powered system on this Audio Circle Diskless thread

Every other USB card I have tried with ASIO drivers (Musiland, XMOS, exaU2I) worked perfectly in this setup with an error rate of 0 even after several hours of running.

I'm starting to think most of the issues I'm seeing are related to the WASAPI implementation and not the Amanero card itself, which means I'm really crossing my fingers for good ASIO support under Windows 7. This WASAPI thing seems like a bit of a crock to me.

I would try installing the latest Thesycon based USB audio class 2 drivers for Windows. It would involve editing some INF files though.

Thanks MrSlim. I do have a dual fan 40 MM liquid system in the works but the power supply is the bigger noise problem - worling on it.

I'll follow your recommendations and report the results.

Thanks

If you are just planning on using this for music, you can think much lower power, with the only spinning part being the media storage disk drive. The Intel Atom board I am using has a 12V AC adapter input, using a laptop power brick (could also use a nice linear supply.. hmmmm) no fans at all

Sorry for leading this off topic.. BCMBob, we can discuss this elsewhere..

My apologies to the members also. It's so easy to drift away to related areas. I'll limit futute posts to the subject at hand.

One last off topic post on your PC.

FYI, I would lose that hard drive if you want to make a quiet PC.

Hard drives make a lot of noise, when you quiet down the fans and PS.

Laptop drives are quieter, SSD is obviously the best for noise (fast too)

Thanks Randy,

I'm looking forward to my first SSD but still hoping the prices will drop a bit. The pic may not show it but that is a 2.5" drive. Media is on a USB external. Remote placement and smartphone control is another option if noise turns out to be a problem.

I've been comparing JRiver's WASAPi with Foobar's (V 3.0- both Push & Event) and there are important two differences. JRiver cannot output 32bit nor 352.8/384KHz through WASPI to the Amanero drivers whereas Foobar can do perfectly.

When Peter was designing the new WASAPI plugin I suggested he used an alternative way to querying the drivers for "accepted" bit depths because I knew my soundcard Xonar ST did indeed accept 32bit WASAPI if fed to it. I don't know exactly what or how he did it but with all WASAPI implementations from different players I've tested it is impossible to go beyond 24bit with the Xonar drivers except with the newest Foobar plugin. Ditto for the Amanero. I suspect the Amanero WDM drivers need a little extra work. Hopefuly ASIO drivers will come soon and have this little bugs fixed.
