Apple TV and Voyage MPD

have tried Voyage MPD on my ATV for a while, I can say this combo is lovely. :-)



i currently have a 4GB CF card installed, preparing the CF is simple, refer to ATV bootloader for details.

when you have completed the preparation using ATV bootloader, don't partition and format your disk again during Voyage MPD installation, otherwise you may not be able to boot properly.

when you have completed the installation of Voyage MPD, you may have to manually edit the menu.lst file, i have changed the kernel image to its absolute path instead of a link.

here is my menu.lst file,

root@voyage:/boot/grub# cat menu.lst

initrd /boot/initrd.img-2.6.33.7-rt29-voyage
boot

since my USB interface is fully comply to UAC2, it works right away.

streaming 384kHz audio is just a piece of cake. :-)




here is the official Voyage MPD site,

http://linux.voyage.hk/voyage-mpd

will upgrade to Voyage MPD 0.7.5 soon

upgraded to 32-bit

with a new firmware update, the USB interface is now capable to stream at a max. of 384kHz/32bit.

ready to ship

the new usb interface module is ready to ship now. :-)



the proposed price is:

1. 192kHz/24 bit version --- US$199
2. 384kHz/24 bit version --- US$249
