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

title AppleTV-MPD
root (hd0,3) kernel /boot/vmlinuz-2.6.33.7-rt29-voyage root=/dev/hda4
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,

full throttle

my new USB audio interface is now capable of delivering audio sample up to 384kHz sample rate.

here is the reported sample rate supported by Mac OS:





playing hi-rez audio files is really fun. :-)

hacking Apple TV

after some listening test, i have decided to settle with linux and setting up a new cas system using an Apple TV (1st gen).



a minimal linux system will be "poured" inside this little machine and act a frontend music player. all of my music files will be placed in a NAS.

since the Apple TV (atv) is using a Pentium M processor and almost any standard x86 linux distribution will do the job.

a peep inside of the atv,



atv is not using standard BIOS, you will need a special bootstrap process in order to boot into a new OS other the standard ATV OS, i've tried this,

atv-bootloader

it works! :-)
