'Analog Dinosaur' succumbs to the joys of FBA : enter Raspberry Pi 2/IQ-Audio DAC+!!

Hi Marco,

I'm not so sure, but I think yes, you should reflash the sd card and make all the necessary settings again.

Yes I suspect that's the case, and if so, I won't be going there, as it's beyond my knowledge or desire not to fuck up things.

There is an app named PlugPlayer, available for Mac, iOS and Android. It must be installed on your Mac and you should do nothing to the RPi (except to enable the UPNP settings on the RPi). I use it with my ipad and it works flawlessly. It is a paid app, but costs just a few quids. The RPi acts as a DMR (digital media renderer) and can be controlled by PlugPlayer. When you start the app, it investigates the net music storages and the players, connected to your network. Just choose the storage and the player. It shows the album art, creates playlists and so on. Great fun...

That sounds interesting and less 'invasive' than fannying around with SD cards. Do you purchase it from the iTunes store?

Marco.

It's not just about speed. Theres less chance of Fragmentation with C10

I see... I wouldn't even know what that was! Thing is, I've got a stupendous sound going on here now with the Pi, and it works 100% flawlessly, day in day out, so have no real desire to piss about any further with the set-up

Marco.

Yup

Ok, noted

Ask Duncan to send you another SD card with Moode installed Marco, then just swap them over and boot up!

[Marco]

Yes, that could be an idea.....

Hi guys I'm new to the raspberry pi mumbo Jumbo but from what I'm hearing it sounds amazing, could someone please send me a Pm and tell me what I need to buy please from this thread there is so much being discussed and from a non techy stand point it's a little confusing, thanks

Hi Deano, I've PM'd you to look at this post, not sure if you've been PM'd this already, but someone on here posted these links a few pages ago:

List of all you need etc.

There is a list quite early on on this thread too (somewhere ).

All the best,

Phil.

? Run that one past again Andre....where does the speed rating of an SD card affect file system fragmentation?

[The Barbarian]

Here found this. This will explain better

Thanks Andre but I think you've misread it, easy to do....

The memory of a card is divided into minimum memory units. The device writes data onto memory units where no data is already stored. As available memory becomes divided into smaller units through normal use, this leads to an increase in non-linear, or fragmented storage. The amount of fragmentation can reduce write speeds, so faster SD memory card speed standards help compensate for fragmentation.

What they are saying is that during normal file system usage as file are deleted and others written fragmentation occurs which can affect the write performance (by adding write latency) of the flash memory. The higher classes of card offset this increased write latency by being faster in the first place so the effect is less noticeable.

On another note these classifications of speed class are for sequential continuous writes. When an SD card is used in a computer environment, like on our RPi's the card is subjected to a small block random read and write pattern, not sequential write (well only at the time of creating the image) so the most important parameter for the card and it's not often if at all published is the 4K block random read/write performance.

There is a thread over on the RPi forum where this is explained and a whole bunch of performance results posted on numerous different SD cards. It may surprise you that some of the fastest performing cards in this 4K random test are Class4 cards and not Class10...
