Andy must be very busy with Canjam, Firmware 2.0 just released in Cayin China website, not yet available in their international website, here is the link
http://cn.cayin.cn/down?name=iDAP-6+V2.0.zip
Google translate, but i try to rewrite some of it using my limited Chinese knowledge
iDAP-6 firmware V2.0 version of the new content
1, add shutdown timer, and make shutdown function idling (this one i don't understand);
2, add support for Opus Codec encoded music files;
3, optimize the song information display interface;
4, rectify the bug when connected via I2S interface, the DSD file left and right channel are reversed, advance to next song will back to normal;
5, Rectify the bug when your smartphone is connected to IDap-6 using HibyLink, and if you plugged new USB devices into OTG 1,2,3, the Hibylink app on your smartphone will show the newly added USB drive's directory, and you will be able to play the music file inside, BUT the capacity of directory is ZERO; (My problem on Hibylink is when added new USB drive after pairing IDap-6 and smartphone, the newly added USB drive will not show up in Hibylink, I need to un-paired and re-paired them in order to show the newly added USB drive)
6, optimize other BUG.
