Hi there mikelangeloz,

First of all, congrats on producing something for those of us using a Raspberry Pi as a front end. I had been using a MacMini with A+ until recently, but have found the sound to be better using my RPi (with modified PS) and an offboard USB/SPDIF converter.

I have spent a bit of time getting my version of Debian with MPD working to my satisfaction, and to my ears it sounds very good indeed, and is very stable.

Whilst I am interested in your project, it would be a big jump for me to abandon my current set-up and move to something new.

In light of the above, would it be possible to briefly outline some of the changes made to the kernel and in particular to the alsa, which will directly improve sound?

Many thanks!

my initial enthusiasm for raspyFi has somewhat worn off after i updated some packages and suddenly had a lot of hang ups when playing flac files.
I booted with the original image and the hang ups were gone.
While this proves the changes in raspyFi to be effective, it also makes it pretty much a "better leave it as it alone" system.
This does not make raspyFi a bad solution, but its closed an monolithic design probably makes me the wrong target group.

I would prefer a more modular approach.
1. some kind of Makefile, Buildfile or setup skript that recreates the optimizations on different systems and helps with the configuration.
2. a http frontend, that also could be run on an external system, taking the load from the RPi. This is optional.

I think the Buildfile/setup skript would also benefit inexperienced users, who have problems creating an image on a SD-Card.
They could install via Noob and then run the Setup Wizard.
Furthermore the modular approach would facilitate a port to other boards.


For now i have abandoned the raspyFi image as felt to limited in the changes i could do to the setup.
Now I have setup archlinux and use hdmi to connect to my AVR.
For my kitchen speaker i will use the zone 2.
Control of the AVR and the RPi will be done via a webinterface.
The Sound quality so far is rather good. Although there is the occasional hang up. I suspect these to be caused by dropped packets. (eth0: kevent 2 may have been dropped).

Will see whether
gpu_mem=32
smsc95xx.turbo_mode=N
and
vm.min_free_kbytes = 8192

can fix that.

Help, Damn I been trying this all evening.

I extracted RaspyFi1.0.img to my desktop and in Terminal I do this

deek@deek-OptiPlex-GX280:~$ cd ~/Desktop
deek@deek-OptiPlex-GX280:~/Desktop$ dd if=RasbyFi1.0.img of=/dev/sdg
dd: opening `RasbyFi1.0.img': No such file or directory

I'm going Nuts, please save me?

Thanks
Mike

The dollar sign tells me you are not root. Guessing you might need to be for something as fundamental as this?

On a separate note, I am as Linux-geeky as the next guy in a black t-shirt, however I would still create an SD card image on a Windoze machine as it is just a lot more straightforward (and 'offline').

try ./RasbyFi1.0.img

probably . is not in your PATH.

and yes you need to be root (or sudo) to do this.

Ok, second eror is different from the first.
You need root permission.
If your /etc/sudoers is configured correctly you can use
sudo dd if=RasbyFi1.0.img of=/dev/sdg bs=1M

else you need to login as root.
use su

or CTRL-ALT F2
which brings you to a tty (no gui)
login as root.

Just to make it absolutely clear; you should probably use ./ as the path too, as rawdlite suggested earlier.

sudo dd if=./RasbyFi1.0.img of=/dev/sdg bs=1M

The leading dot is not required, the search for PATH dirs applies only to execution, not to reading/writing.

Clearly the img file was not located in the current working directory (different directory, different name). That is why the error says "File not found" :-)

Aaah, didn't get that.
Forget what I said then!
