FYI lots of interesting digital and analog circuits and modules available at http://www.twistedpearaudio.com . I found one that has a WM8804 for $75.00 assembled, or $14.00 for the PCB, but I don't think it's configured correctly. Regarding whether it can be configured differently, here's a question I posted to their forum, and some links to similar mods on the Roland SoundCanvas SC-88, the Yamaha MU-10, and a Nintendo Gamecube.... ...................... http://www.twistedpearaudio.com/forum/default.aspx?g=posts&m=5968&; I'm interested in tapping internal I2S outputs from working soundcards&syths with outdated analog sections and exporting their output to S/PDIF, rather than S/PDIF to I2S (see http://linuxaudio.org/mailarchive/lau/2010/6/25/170787 ). I was excited to find that this module was cheaper than the $200.00 WM8804 evaluation board that appears to be able to perform this task, but less enthusiastic after clicking on the "transceiver" link and landing on the "S/PDIF receiver" link instead. Is there a way to enable the other direction of signalling -- I2S->S/PDIF -- on this "S/PDIF receiver" board? Or do I need to the Wolfson WM8804-6152-DS20-EV1 board ( http://www.mouser.com/ProductDetail/Wolfson-Microelectronics/WM8804-6152-DS20-EV1/?qs=Xqu1B/s4UobSmDPf34PglA%3d%3d ) Another alternative is to find a hard to find and overpriced Toshiba TC9231N ( http://pdfserv.datasheetpro.net/ToshibaSemiconductor/TC9231N.pdf -- $76.00 just for the chip ) using a circuit like http://gamesx.com/wiki/doku.php?id=av%3Anintendogcda but using a 11.2896Mhz xtal for 44.1K instead of a 12.288Mhz crystal for 48K rate of Nintendo box from above link. Other older devices interfaced similarly include a Roland SoundCanvas SC88 and a Yamaha MU-10: http://nfggames.com/forum2/index.php?topic=4063.0;imode http://www3.big.or.jp/%7Efujikko/sc88vl/kaizo.html http://www.uyouyo.com/special/soundcrd/sc88.htm -- Niels. http://nielsmayer.com _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
