XMOS-based Asynchronous USB to I2S interface

[jrling]

I use mpdPuppy and am very pleased with the SQ.
I chose it because of its ease of install, exceedingly small size and the excellent support by the administrator.

Having been a Windows user for a lifetime, I am so pleased that I gave Linux a go and it is well worth it for the SQ improvement it brings.

Wow, very impressive! I wish it were the other way (I2S-->USB) also so that I could use it with a high performance ADC for test and measurement.

Still waiting for info if anyone tried mix WaveIO+Ians FIFO board?

Btw had anyone problems with connectin WaveIo to laptop? It doesnt want to communicate either wirh USB powered or by external PS - theres communicate like "broken USB device" or something similiar. My friend has such problems. Reinstalling USb drivers dont help. USB works properly with pendrive etc. WaveIO works perfect with desktop PC but everytime friend wants to conenct it to laptop there is such error. System is Windows 7 64bit.
Any tips?

Im working on the FIFO, had many dramas at home and hope Ian's patience hasn't run out so I can still get my order! Did let him know and he has been very understanding, looking forward to seeing(hearing?) this in action...

Ok guys I have few thoughts to share after testing WaveIO myself and with friend Ill describe main issues:

1. WaveIO seems to NOT bypass windows mixer. Even I have ASIO Luckit driver chosen I still can slide windows volume control to increase/decrease volume. Why? Whats wrong?

2. My friend wasnt able to connect it to laptop, EVEN he used external power supply. After connecting to USB it shows "broken USB device" or something like that. The same settings work perfect at desktop PC. Searching problem in progress.

3. No matter what type of music file you start play device it shows ALWAYS current sample 44100. Whats wrong there, why theres no change when hires file is starting? Where is mistake?

All tips are welcome

what playback software are you using? On windoz, I believe the most recommended software is Jriver media center. Not a windoz guy myself, I prefer to use a linux based server, and before a Mac with Pure Music.

I tried JRiver, JPlay, Foobar etc. Regarding problem No. 1 I had it in every occassion and still could use windows mixer slider to operate volume. It happened on ASIO by Luckit and Asio4ALL with all other sound devices off in system or even in BIOS.
Problem No. 2 is investigating as it could be mess with drivers etc.
However theres still problem No. 3 described by my friend whos testing now WaveIO. Installing ASIO4ALL helped to change files formats to 48 and 96 but NONE of drivers are able to play 196 kHz files - theres info that type of file is unsupported??
Also Luckit USB Panel looks like inactive and shows constant 44.1 stream format.
I cannot see these problem right now as I dont have WaveIO here but first problem I experienced by myself.
Using Windows 7 64 bit both me myself and friend.

I have the Wave IO up and running with with Ian's FIFO and a Buffalo 2 DAC. There has defiantly been an increase in SQ when I installed the FIFO with the supplied "test" clock modules although I am waiting on a couple of Tent Labs clocks which I hope will bring out the FIFO's full potential.

Note, The Wave IO is no longer bus powered and has it's own 5V supply, This also brought a surprising improvement.

Best Regards,

James.
