New GigaByte Z87X mobo with RelTek HD audio Manager.
Have installed, then re-installed audio drivers from GigaByte.
- Set RealTek HD Audio Manager to "Speakers".
- Maximize volume
- Note that analog back panel highlights receptacle that amplified
speakers are plugged in to.
- Turn amplified speakers' amplifier up to max - giving a low-level of
- Note that varying Windows' volume control has no effect on level
of white noise.
- Un-plug amplified speakers and note that white nose goes away.
- Plug amplified speakers into the same port on another PC, play some
music, and they work a-ok.
- Plug amplified speakers back into problem PC
- Open up Speakers | Sounds | Program Events
- Choose a sound.
- Click "Test", and the white noise stops for the duration of the sound,
but no sound comes out of speakers.
I'm doing something dumb.... but what?
Don't know which version of Realtek's HD Audio Manager program you are
using. I have it show an icon in the system tray (but configured to
hide into the expanded view of the tray icon). I double-click on that
tray icon to show the Realtek HD Audio Manager. That is the RAVCpl64.exe
process in Task Manager's Applications tab. It is found under
C:\Program Files\Realtek\Audio\HDA\RAVCpl64.exe. I have the 64-bit
version of Windows 7 Home Edition x64 SP-1. You never mentioned which
bitwidth of the OS that you have. The program does not let you see what
version it is. That's why I needed the filename so I could right-click
on it to look at Properties -> Details.
I only have 2 front speakers (no rear, center, or bass [which is taken
care of by the Altec speakers themselves]). Under its Speaker
Configuration tab, I have "stereo" selected for Speaker Configuration
selection because I only connect to the stereo output - with the
backpanel display in the program shows as the green-colored jack (it is
bold, the others are grayed out). Also, "Full-range Speakers" is
enabled for "Front left and right" (the "Surround speakers" selection is
grayed out because I only have the 2 front speakers).
In the program itself, clicking on the "i" information button says:
Audio driver version: 22.214.171.12498
DirectX version: 11.0
Audio Controller: HD Audio
Audio Codec: ALC888S
Some or all of that would be different because you have different
hardware than do I. When I right-click on the RAVCpl64.exe and go to
Properties -> Details, both file and product versions are 126.96.36.1996.
Neither in the Realtek program, its tray icon, or the Windows volume
tray icon are the speakers shown as muted.
The white noise is likely due to EMF induced into the chassis and ground
plane of the mobo from A/C power line or radio. When your speakers get
a signal, even a tiny one enough for it to detect there is a signal, it
probably uses some filtering to improve the quality of sound. So the
noise from the speakers goes away when you attempt to play some sound.
That tool only configures how the driver will tell the hardware on the
motherboard to be configured, not what Windows will use to where it
sends its audio output. Right-click on the Windows volume tray icon and
select Volume Mixer. Are either speakers or system sounds shown muted?
Right-click on the volume tray icon again and choose Volume Control
Options. Is the "All devices currently playing sound" option enabled?
Right-click on the volume tray icon again and pick Playback devices.
Windows differentiates between which "devices" (defined in the registry)
are used for playback and which are used for recording. That brings up
the Sound applet (same if you go into Control Panel -> Sound). For me
with my 2 speaker setup, and with the Playback tab selected, I scroll
down to find the Speakers device selected for output. It is also
selected as the default playback device. With it select, click on
Properties. Under the Levels tab, the Realtek HD Audio Output slider is
set at 40% which is also what the Windows volume tray icon shows, and
not muted. The other controls shown are for inputs. Two are disabled
(microphone - rear jack, front mic) and one is enabled (line-in). Since
I'm not using them, I could mute them, event the line-in jack.
Back in the Sound applet under its Playback tab and with the Speakers
device selected, I click on Configure. That gives me the test wizard
and maybe what you used. Since I only have 2 speakers (front), Audio
Channels is set to "Stereo". I click on the Test button and hear the
down-chime tone in the left speaker followed by the up-chime tone in the
right speaker. I click Next and see the full-range setting. Despite
seeing it enabled in another view, it is deselected here. I can enable
or disable it, click on a speaker to test, but hear no difference.
Alas, they play a mid-range chime tone without any bass so I won't be
able to tell the difference. Clicking Next just brings me to a summary
screen where I click Finish.
While you might have the Realtek tool properly configured for the
hardware how you want to use it, you still need to tell Windows which
device you want it to use for playback and recording. Under Sound ->
Playback, I have 6 digital audio devices defined, 2 "speaker" devices
defined (one shown with an RCA coax cord but I'm not using the coax jack
and another as a speaker icon and that one is selected as the default
playback device), another digital device (probably the optical output),
and an HDMI device (not using that jack, either). If you have a mic or
might later get one, go under the Recording tab and make sure one of
those inputs is selected as the default.
