Windows 7 and Networked Audio Receivers

I have a client with Windows 7 Ultimate and a Yamaha AX-1000 Receiver that connects to network and plays a/v through Windows sharing.  This used to work fine but now doesn't after having to load Win7 onto new hdd.
The receiver sees the files no problem and "plays" them but no audio comes out.  I am trying to do this remotely with my client so not in front of rcvr.  I have checked and re-checked all firewall settings and Windows 7 homegroup advanced sharing options and all look perfect.

Trying to picture your setup there
where is the audio problem?
This receiver would not have changed from XP to windows 7 so the change is how windows 7 is receiving it?
The receiver sees the files no problem and "plays" them but no audio comes out.<<
How do you have this receiver connected to windows 7? and what is it playing in?
refs to>
connects to network and plays a/v through Windows sharing.<< is this within Windows Media player?
Have you enabled streaming in WMP?
Need more details of which windows 7 is the server or the host for the receiver what sound card is on this system.
Have you looked into the sound options r/click the speaker icon on the taskbar
playback > speakers is ticked? and your default sound card is listed below in the output.
highlight speakers>properties>enhancements>untick everything except for equalizer
and there is none in the settings.
I'll endeavour to assist you further with your feedback

I will be working with this client more remotely later today.  The receiver is located elsewhere in the house and connects via Windows network sharing.  The receiver sees the others computers in the workgroup and can access the shared files just fine.  But, when the receiver plays a music file, it runs and shows it's playing on it's progress bar, but there is no sound.  I've asked him to check and double-check his settings and he states that nothing has changed.
This Windows 7 system is just like it was before the hard drive failed.  Both were Windows 7 Ultimate systems.  The first incarnation worked just fine after getting the receiver to see the Windows shared PC's successfully.  He claims that he's changed nothing on the receiver.  I even changed the Windows name of this system when I rebuilt it so there would be no naming confusions.
Not sure what's happening here.
Thanks for the suggestions.  I will double-check those WMP settings and the Windows sound settings.

Is this the receiver.
I'm old school I guess, so the receiver is getting the files off the windows 7 ( streamed to ) from shared network,
you may have to update the firmware, if there is access via shortcuts r/click that shortcut and run as administrator.
Check all the correct input source is selected is and the audio is not muted.
Cables ok?
If nothing has changed then it must be a setting on the receiver.
Pity he didnt save the settings from the previous windows.
I cannot find a manual for this model, is it the correct model listed?
What does it mean to be "Always On"?

This is Windows 7?
It usually bundles with WMP 12?
Where did you get that information  ve3ofa refs to>it states that it uses windows media player 11
From what I have found in other guides from Yamaha  windows 7 is supported.
The files are streaming fine just no audio

I dont know if it would make a difference but I'd ensure everything is as it was, and upgrade the WMP 11 to WMP 12 if that is the case.
I believe it is in the area of the sound output.
Look in the audio output playback again
since the speakers properties has been checked select the digital output and make it default this time
then open properties
supported formats
enhancements none
advanced select the sample rate output and test

I'd then reboot the system
Sometimes it can be a sequence of how things are connected.
Ensure WMP is the Deafult player this oftens fixe audio playback
install ffdshow that should fix any codec issues

Thanks all for your input for this question.  I have figured out what the culprit was in our situation and what our solution was.

As I stated before, this was working fine before on this PC's previous Windows 7 incarnation.
We did have issues the first time hooking the systems up, but they were resolved and we both couldn't remember exactly what the solution was for that time, but it had something to do with Firewall and Security settings.

After checking again that all Windows 7 advanced & workgroup sharing options were done correctly and after double-checking on the Windows media sharing options for each networked device I felt all that was correct.  Also, I double-checked all settings in our security suite to make sure they would allow through firewall and other settings and that was all fine, as well.  We did have a couple notes from the first install regarding ESET, and had performed those suggested actions already, so figured that was covered.  However, I just wanted to be sure.

FIRST - I performed a complete uninstall of ESET Smart Security 4, since I wanted to put the new version 5 on anyway.  Restarted both the receiver and the PC.  (By the way, for all newbies out there, most receivers don't completely power-down so that they are completely and utterly power-less.  A lot of them go into "Stand-By" mode so they don't totally lose power.  Thus, you won't be able to successfully reset and/or refresh the amplifier/reciever and force it to reconnect to the network and re-establish new or changed PC workgroup settings.  Some of you may actually have to unplug the power cord to get it completely powered off!

SECOND - Tested the receiver's ability to actually play the shared sound files from the PC without the security suite installed.  This time we could actually HEAR SOUND!  So, I knew that ESET was causing the blockage due to strict firewall settings.

THIRD - Reinstalled the new version of ESET Smart Security 5 (fantastic product by the way!) Set all my usual Network & Firewall settings, etc.  Then went and changed from Automatic Detection mode to INTERACTIVE MODE firewall mode, so that I could see and react to EVERY PC detection and "Allow" or "Deny" policies manually.  Restarted the PC again.  Waited for each message to come up and permanently Allowed anything I needed to (and also created rule for it to remain intact after changing back to auto), until finally one came up for WINDOWS MEDIA NETWORK SHARING SERVICE, something to that effect, and I allowed permanently.  I felt sure this was the culprit.  After waiting awhile for all possible pop-ups to come up after the PC had gone through a restart, I turned the ESET Firewall option back to automatic with exceptions.
The receiver now works and plays the shared music tracks WITH ACTUAL SOUND OUTPUT !!

FOURTH - Note: There were also a couple of other settings having to do with un-checking detection of DNS and ARP port snooping attacks which ESET had told us to do previously.  I went ahead and did that again this time, but will go back and re-activate those and see if that changes anything.  I don't want to turn that feature off for obvious security reasons.  I will update this record to advise outcome.

Thanks All for your Input and hope this helps somebody else!

Glad you got it fixed.. Third party firewalls make things non standard and you forgot to mention that you were using ESET security suite..

@merete: the reference to wmp11 was from the yamaha website in the user manual that was buried somewhere in the links you provided. If there is no audio then the file is really not streaming fine as it turns out it was being blocked by his firewall and the receiver had to had to have a power off reset to reset its network settings.

Thanks for providing that extra bit of information Yve3ofa
So the actual problem was a hard reset  full power off was required by the receiver in order to renew the network settings.
Yes that makes sense, when reseting a computer I always pull out the power cord as that  action completely stops all power connection.
Glad to see you found the solution TallTech and thanks for sharing it.
Best Wishes
