Sound/AC'97 Audio Codecs
  • Q1: Could you please advice me which driver I should download for my sound card?
  • Q2: I downloaded the latest drivers of Windows updates for my sound chip and it installed a sound effect manager in my taskbar. There are no options to disable or remove this feature. What can I do?
  • Q3: Would the ALCXXX support DOS mode drivers ?
  • Q4: I am using Windows 98 4.10.1998. When installing drivers for win 95/98, I have delay in sounds in games like FIFA 2001. With the win 98 SE drivers all is OK. Why the drivers for win 98 are different from the drivers for win 98SE? The SPIDF would be in the "device manager"? Why my Power DVD doesn't recognize the SPDIF output? The SPDIF output is in communication with the Realtek chip?
  • Q5: Will your AC'97 audio CODECs support non-Windows XX or Windows 3.X operating systems, e.g., Solaris, Linux, BSD, etc. in the future? Do you plan to release information regarding implementation, hardware specifications, etc.?
  • Q6: When I ran the Microsoft DirectX Diagnostic tool (Dxdiag.exe) sound test on a computer with Realtek audio driver (Windows Driver Model) installed, the test did not run properly, and the operating system showed the following message: "Your sound card does not support hardware buffering. Sound will only playback from software buffers." What does this mean?
  • Q7: I've set the AC'97 audio configuration utility to 4-channel mode and when I tested the speaker, the rear worked, but when I wanted to listen to some audio (mp3), only the front speakers worked properly, the rear speakers didn't work well and with a lot of noises.
