The sound on my computer has completely gone. the volume icon is missing. I have an
onboard Realtek AC97 sound device.
All of a sudden, the other day i swithed on the pc and no sound. device manager reports no
audio problems, however system information says that IRQ 16 is being used by a graphics
controller and usb universal host controller. in control panel under sounds and audio
devices i get a "no audio device" message. the last two programs i installed are windows
media player 11 and IE 7.0 about two weeks ago, and the problem starter yesterday.
i have tried system restore to no avail. BIOS sound is enabled. speakers work just fine on
another pc. i can't Extract a copy of Sndvol32.exe from windows xp cd because all i have
are the three restore cd's when i bought the pc, and when i try to reinstall audio drivers
via the restore cd or from C:\Drivers\Audio\OriginalDriver the system stops installing at
80% and i get the following:"Realteck ac'97 audio (4.86) tool for driver update has
encountered a problem and needs to close."
i tried unistalling realtek ac'97 in add/remove programs but i get the following pop up:
realtek ac'97 audio
pAPP:Realtek ac'97 audio
PVENDOR:Realtek semiconductor corp.
@windows XP service pack 2 (2600) IE 7.0.5700.6
Setup has experienced an error.
Please do the following:
- Close any running programs
- Empty your temporary folder
- Check your internet connection (Internet-based Setups)
error code 5001
when i run directX diagnostic tool i get the following:
Sound Tab 1: DirectSound test results: Failure at step 3 (DirectSoundCreate): HRESULT =
0x8878000a (The request failed because DirectSound resources, such as the priority level,
were already in use by another caller.) and
Music Tab: DirectMusic test results: Failure at step 6 (Activating the IDirectMusicPort):
HRESULT = 0x8878000a (The request failed because DirectSound resources, such as the
priority level, were already in use by another caller.)
device manager shows the following under sound, video and game controllers:
audio codecs, legacy audio drivers, legacy video capture drivers, media control devices,
and video codecs. each device is enabled and supposedly "working properly".
when i installed a pci sound card the volum icon does come back and i can hear music, but
i'd like to figure out the audio problem.
i know i can do a windows xp re-install but that is going to be my last option.
what do you guys think?
