Re: Noice on analouge audio with mpd

These white noised are couse bad driver (hopefully it will be improved).
I have got rid of them by using USB sound card, audio quality is much better and no noises!

Re: Copying SD Cards

You can even make backup over net without stopping raspberry. All you need is netcat and (not necessery but very useful) pipeviewer (pv). examples:

# on normal pc
nc -l -p 5556 | pv | dd of=raspberry_pi_bak_2012_06_01.img.gz

# on raspberry
sudo dd if=/dev/mmcblk0 | gzip -9 | ncat 192.168.1.101 5556

Re: broken kernel image?

Ok, apperently I was right.

On https://github.com/raspberrypi/firmware there is new kernel.img which is not included to arch packages! OMG, why? I replaced kernel.img and system boot (only hdmi video dont work now :/).
