Sound card drivers installed TV card can not lead to the broadcasting of television programs
Trouble phenomenon: reinstalling WinXP system, the first turn on the TV card procedures when watching television programs, sound card can be the normal pronunciation, but after switching to other channels, television programs on a sound. Quit after the television program re-open them. Can only restart the computer, watching television programs when it can have the voice, but as long as a conversion after the program channels, continue to repeat the failure. Moreover, the fault only in the use of video cards when the emergence of fault occurred in the front and rear, other multimedia files player, sound card can be the normal pronunciation.
Troubleshooting: As the TV card is through an audio line, connected to the sound card line input before they can watch TV programs from time to time the voice, so I put this audio cable pulled out directly to the speaker received a TV card audio output port, resulting in a normal voice, which is excluded from the TV card sound output problems, and in the replacement of cable, the problem still remains. Therefore, I determined that the computer’s sound card problem.
Troubleshooting process: as a result of watching TV programs in a silent failure, the computer player other multimedia files, sound card can be a normal voice, so I suspect that the sound card drivers and TV card driver are in conflict, but in my sound card driver to uninstall process, the computer could automatically restart, and not be able to use Safe Mode to enter the system. Later, I came BIOS settings to disable the sound card after the original sound card can uninstall the driver. Uninstall sound card drivers, I BIOS settings to re-open the sound card into the computer so that WinXP automatically search for the motherboard driver disc sound card driver, the system quickly find out the location of the driver and automatically install good sound card driver, but the fault still exists.
After the re-TV card driver also does not solve the problem, because before reinstalling the operating system, the computer can be a normal television programs. Is not a TV card and motherboard integrated sound card is not compatible then? With this doubt, I look at the TV card and the motherboard manual, but manuals are written WinXP systems compatible. The motherboard manual to write the sound card model, it caught my attention because the motherboard manual to write sound card model is CMI9739, and just automatically install the sound card driver, when it is installed ALC100 sound card driver. In order to determine the sound card model, I opened the box and found the sound card chip motherboard is CMI9739. After I put the original sound card drivers to uninstall, then reinstall the CMI9739 sound card drivers, troubleshooting.
Maintenance experience: Generally speaking, the installation of the wrong sound card driver, the computer is not the normal pronunciation, but I try on another computer, then find the installation of ALC Series sound card drivers, the integrated chip VTI612A and CMI9739 motherboard can be the normal pronunciation, but will appear with the TV card is not compatible problem. And often in the WinXP operating system to install the driver process, we all used to the next step only point to the neglect of the system to automatically find out the driver to choose. It is proposed that we install the sound card driver, the best look at what the motherboard manual, or look on the motherboard sound card chip models.
