Multi-room Audio - a tad confused

[gurumaia]

A little bit different, but if all you want is background music what you have picked should be fine. Not running LMCe at work but run these ceiling speakers

with this amp
http://www.jaycar.com.au/productView.asp?ID=AA0472&keywords=power+amplifier&form=KEYWORD

They won't ship overseas but probably similar to what you are looking at and it all works fine so I think a lower powered amp and cheap speakers do work fine.

Good, so I guess even these cheap amps will be okay for now.
Now I only have to settle on speakers. Since they are a little bulky I might try to buy them here, to avoid the high shipping rates. Can anyone recommend some okay brands? I would like to spend a little more money on the speakers, so that I don't have to exchange them when I switch to better amps.

Thanks a lot for the help! I hope my LinuxMCE system proves to be as good as I'm imagining!

Got one of the branded 7.1 usb soundcards from ebay when I read this thread ....

Problem is, it is listed in lsusb as :
C-Media Electronics, Inc. Audio Adapter

... but not listed using:
squeezeslave -L

Any suggestions?

[b4rney]

@Coley, Yes, all done with 'sudo -s'.

dmesg output looks big. Should I filter with grep?
If I use:
dmesg | grep -i usb
There is no output.

had a lot of problem getting squeezeslave to see these cmedia usb audio cards and talked to the squeezeslave developer about it.
In the end i never really got it working with a Cmedia and bought some other brands that did show up.

What version of squeezeslave are you using? you could try to update to the latest and see if it gets detected now. There were some issues with the stream or something, can't really remember, the developer might have fixed it.

Hi Richard,

Yeah, I saw your thread too. Thanks for the info. Didn't realise we shared the same hardware.

Might have to find the hardware Andrew recommends.

Installed using apt-get install squeezeslave.
Regards
Barney

[b4rney]

Found it:

Code:

root@dcerouter:~# dpkg -l | grep squeezeslave
ii  squeezeslave                               0.9-133-svn172   

[rperre]

yes, that's an old version from march last year, try to build it yourself and see if these devices are detected better.
Looks like they are at 1.0 r210

http://code.google.com/p/squeezeslave/downloads/list

I will look at this when i get back home sunday, i don't have access to my system atm.

Richard

P.S. squeezeslave -v should give you the version

[b4rney]

Tried latest build but the device is still not listed.

I have ordered the model recommended by totallymaxed.
Thanks for the help.

Hey barney, sorry to see you're having trouble with it. Did you buy the one I linked a few replies back? And which one did you buy now?

On a related topic, maybe we should start building an HCL (or is there already one? I couldn't find it on the wiki). It should help us avoid these issues in the future.

Thanks!

Got this one from ebay.co.uk:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180614238216

This DOES NOT work (see the previous comments).

*** UPDATE***
Now working. Downgraded alsa and it works perfectly.

There are a lot of similar branded items and it is hard to distinguish between them so an HCL might prove difficult.

I think it is a good idea to create an HCL if the product is easily identifiable.

Hi Barney,

Below is the output from lsusb & aplay on a Dianemo 10.10 system for a C-Media USB Audio Card from Startech (basically the same chip as the unit you purchased on eBay...your unit is an 'up-market' model in fact!) I have attached a picture of this card manufactured by Startech below - this unit is detected correctly and functions well with Squeezeslave;
