As you can read in my blog. The flac issue is a pretty well known issue.
You need it decoded on a remote server. Then it's PCM streaming.

I'd recommend to work on your wired ethernet optimizations.

I slightly revised the ethernet chapter. Let see if we can squeeze even more out of it.

Cheers

soundcheck,

may I ask a few questions?

Quote:
Even though the ports are isolated by transformers, ground loops do exist.
Do you have any specific information supporting this statement? Where are the ground loops introduced when using unshielded cables?

In one part, you discuss quality of ethernet switch, in another one you suggest to use a complicated QoS router where all packets are inspected by an embedded CPU and the chances of dropping/delaying packets are much higher (but still entirely negligible, of course).

Joining a shielded cable and unshielded one can be via a simple ethernet junction.

When using unshielded cables there are usually no groundloops.
There has been an article in the German "Stereo" magazine about the impact of ethernet cables. The winner , I think it was a "Monster", didn't have a shield either if a recall it correctly.
They concluded: There is an impact due to cables. But it is not the data of course. They also said one of the main reasons should be HF interferences
finding it's way into the device.

The QoS router is supposed to give multimedia streams a higher priority on the net.

Consider the HUB as a kind of termination point in front of the Touch.

Very constructive comment let's follow up on this one.


Don't forget to have a look at the mixed rates (100MBit vs. 1GBIT) in a Network.


The whole networking discussion I consider much more vague then the
Touch internal mods. Would be nice if the best solution comes out of this discussion. I'll change my proposal accordingly.

BTW. Do you have a Touch up'n running now?

Cheers

Default WLAN with SW mods

As already mentioned in comments on sounchecks blog I think with WLAN connection you could avoid mass loops caused by network wires. So it would be very interesting to have a SW mod. doing same as Soundchecks SW mods for wired connection but usable for WLAN.

Recently Ive downloaded this small applet for my Windows Mobile phone (HTC)
http://sc.sciatec.de/ This turns your mobile phone into a pretty fast remotecontrol for your SBT. It also allows you to have almost full control over your SBT with the display turned off. Which i think could be a better solution than unplugging the display, because the processor then actually turns of the displayprocesses. By unplugging the display, the processor might even try to do some handshake over and over, trying to get in control of the display.

The applet is not freeware, but will cost you 10€, which I find very modest for the convinience it provides.

Im sure there are several others for other Mobile OS, such as Android, iPhone, Nokia etc.

Give it a go

Maybe that would also apply for the iPod and other iThings

Hi guys.

I am using iPeng on iPhone since good old SB Duet times. It is fast, reliable
and IMO pretty well done.


The display mod is not the same as turning the display of with the screensaver.
Just give it a try!

Cheers

Unfortunately that would bring the possibility to control the embedded squeezebox server software to an end.
And I would miss that a lot, since performance in my set-up is much better using an USB HDD than feeding via WLAN or ethernet. It is somewhat slower though, but that is a price Im willing to pay for better SQ.

Using my HTC as remote speeds up reaction time from my SBT to an acceptable level, even though Ive got pretty close to 1TB of music files.

So disconnecting the display does not seem to be an option for me.

Next experiment will be powering my HDD from a linear PSU.
