Realtek HD no sound - Windows 7 RC x64

Did anyone manage to solve this problem?
I'm still strugling with getting sound on my emachines e725 / windows 7 rc x64

My sound only works through external speakers. Bah.

When I plug in my head phones to the front audio panel it will not automatically swap to headphones. I have to change the default from S/PDIF to headphones to hear audio. I get no audio from both at the same time. Only the one set to default.

Setting the sound mixer to show all enabled devices and with S/PDIF set to default I can here a sound through either the head set and speaker when I click on the mixer slider for the devices. There must be setting that ports sound from an application to both at the same time but I have yet to find it.

For those having trouble perhaps this might help. Make sure disconnected and disabled devices will be visible. control panel>change sounds settings. On playback tab right click inside the window that list devices and makes sure these options are selected.

if you have an old cmedia driver from the asus website for x64 systems , you can use him and it works.
beware not to do a setup, but install him from the device manager.
go to your yellow signed high definition audio driver, cick properties and update driver.
go on look in my computer
go on let me pick the driver
it will come the menu with the driver listed, choose the high definition audio driver
choose have disk, it comes the menu from where you can scroll through your computer and choose your driver the cmedia 9880 whql certified for x64 systems, normally only runs under xp and 2000, choose the .inf file and he will install.( the azalia one)
the device manager shows now cmedia high definition audio driver and the red cross by the speaker sign on your desktop is finished.
i couldnt believe it

Hi,

I had the same problem, for some reason the realtek audio software kept messing things up, resulting in no sound.

My solution (cheat) that fixes it:

Step 1. In device manager go to "sound, video & game controllers", right click on realtek audio, and uninstall the realtek drivers.

Step 2. Then refreshed device manager and let windows 7 install its recommended drivers for my onboard audio.

Step 3. Enjoyed actual sound coming from my speakers.

I know this is a cheat, because you dont get all the bells & whistles found in the realtek software, but at least it works.

I have a Gigabyte mobo, realtek sound on board. There are bios selections that must be enabled?????
Also try going to the mobos website, see what drivers they are putting out there. I have never had this issue, so I wonder if its not W7.????? I used to use pci sound cards and had issues because of conflicts with the vid cards. Many pci and pci-e slots get assigned the same irq, 16. Possibly because of all the multiple vid card boards.

Hi,

I had the same problem. After installing an update of windows, there was no sound from my speakers nor from my headphones. I solve it by going to Manage Audio Device in the Control Panel. In the playback tab choose speakers and then click on the properties button. go to the level tab in the properties window and verify that "Realtek HD Audio output" is on 100 (mine was on 0).
