Help - one PC streams audio, the other doesn't

Help - any network experts out there?

I have two computers hardwired via a DHCP-enabled router to my Pioneer SC-LX85 amp; a PC running Windows7 64-bit and a laptop running Windows7 32-bit.

The amp can see the laptop and streams all its music files, including 192kHz/24-bit FLACs, perfectly. But it can't see the PC, no matter how much I shout at it!

I've checked the various configuration sources and the two machines are:-

Control Panel/Network & Sharing Center = both machines show the SC-LX85 in their "Full Network Map".

Control Panel/Devices and Printers = on the laptop, the SC-LX85 shows in the "Devices" area. It doesn't show on the PC and clicking on "Add a Device" doesn't.....

Control Panel/Device Manager/System Devices = on the laptop the SC-LX85 shows in the list. On the PC it doesn't, and clicking on "Scan for hardware changes" doesn't add it.....

Both machines are running Windows Media Player 12 and on both, clicking on "Stream/More streaming options" shows the SC-LX85 in the local network devices panel. And both show it as "Allowed access using default settings" amd "Allowed".

So it seems that on a network level the PC can see the amp, but the amp can't see the PC. And the PC flatly refuses to stream.

Any suggestions most welcome. And in answer to the obvious question "why not just use the laptop", sadly it isn't mine.....

Regards - David

RE: Help - one PC streams audio, the other doesn't

Thanks abacus Bill, but my desktop PC  is already set up as per the ehow instructions, so no change!  Still won't stream.

 

I'm wondering if my virus/firewall software (Ad-Aware Pro) might be a factor?  But it doesn't seem to have any "do you want to stream" type options.....

Hi David

Yes it’s possible as the media streaming option in Win 7 only adjusts its own Firewall.

I am not familiar with your security suite, however there should be an option to allow your Pioneer to access your computer, (You normally have to include the Pioneer in a safe list) check in your firewall log to see what has been blocked and if the Pioneer is in there (It may only show the address not the Pioneer name) there is normally an option to allow it.

You could also temporally disable your firewall to see if the Pioneer can then access your computer, as then you would know whether it was a firewall problem or not.

Hope this helps

Bill

On the Desktop have u done the following ?

 

Control Panel -> Network and Internet -> Network and Sharing Center -> Advanced sharing settings

- Make sure Network Discovery is on.

- Under media streaming, click on choose media streaming options

Change show devices on to All Networks and click Allow All. If a popup appears select Allow all computer and media devices

Click OK, exit

I'm using Ad-Aware Pro, but there dosn't seem to be any "devicse2 options in it.  I'll e-mail their support to see if they have any comments.

 

Many thanks - David

I've tried this and the SC-LX85 is showing under "Local network", but that's where it is in the laptop which does stream.

If I try to change to "All networks" there isn't an " Allow All" option - just the "OK"?

It should look something like this...

Note the 'Allow All' and 'Block All' radio buttons on the top right. Check that all devices are allowed (tick in the box)

RE: Help - one PC streams audio, the other doesn't

Update for those who've been kind enough to reply....  I e-mailed Ad-Aware support (my virus checker/firewall) and they were incredibly helpful - their suggestions as to various hidden tweaks to the firewall worked.   Problem now solved 95%!

My amp can now "see" the music files on my PC , but one issue is left.  It can see both FLAC files and m4a files, but it will only play the m4a.

The FLAC files play fine on the PC itself, so I know they are valid and not corrupted in any way.

I've asked Ad-Aware if there any filter settings in it that will allow external devices to see files through the firewall, but stop the external device from playing/accessing them.  Just waiting for a reply. 

Ultimately this could even be simply a W7 64-bit DRM issue even though the files are DRM-free......

Regards - David

I dont use Mediaplayer very often. Open WMP, click stream, and make sure "Automatically allow all devices to play my media is selected"

WMP doesnt support FLAC by default so.....

 

...I suggest downloading and using another UPNP/DLNA server - something like 'PS3 Media Server'. I suspect it will then work like magic.

If you want to play virtually any file out there with WMP, download and install the Windows 7 Codec Pack http://download.cnet.com/Windows-7-Codec-Pack/3000-13632_4-10965840.html and you will be good to go.
