Yes, those pins are muxed. > So if someone has a codec chip on a breadboard that they can easily > connect to those pins you can probably get I2S going in about a day.

I am planning to make a main board for the Toplink miniPCIe module, including an I2S codec, but it is not even on paper yet:) > Note that I2S support on the MIPS core is limited at 44.1Khz 16b > stereo. It is very basic. Modern I2S will do 192K/24b audio. But 44.1 > is fine for playing mp3's. Who wants to build a Sonos clone? Thanks for the tip.

Thanks for the proposal, I may be interested as soon as I have the board working! -- Michel > -- > Jon Smirl > jonsm...@gmail.com > _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
