The computer originally had an integrated sound card on the motherboard, but later I bought an independent sound card and installed it. After installing the driver, I can see that it is normal from the "Device Manager". There is also a small speaker icon in the desktop taskbar tray, but there is no sound when playing with the player.

This is because a sound card was originally integrated on the computer motherboard, and when an independent sound card was installed later, the original integrated sound card still exists, so it causes a conflict between the two sound cards. At this time, one sound card must be specified. Open "Cont … View >>>

When the system starts, the sound is normal, but as long as the music file is played, it will freeze, and it will not work after checking and killing the virus. Check in the "Device Manager" and find that all devices are displayed normally. Later, open "System Information" → "Components" → "Problem Devices", the device: ACPI IRQ Holder for PCI IRQ steering, PNP device ID: ACPI\*PNPOCOF\ 00000002, error code: 22 appears in the right column. After testing, it seems that there is a conflict in the equipment, but it cannot be corrected.

From the description of the fault phenomenon, this situation should have nothing to do with the virus. The virus will not only infect the driver of one device without affecting other files. The main reason for this situation is that the equipment cannot be used normally due to interruption conflicts … View >>>

The computer uses a 5-channel sound card, but even if the speakers are adjusted to 4 boxes, some games can only get the audio output in 2-channel mode. What is the reason?

The existing PCI 128 driver allows 5-channel audio output for any Direct X-based game, but cannot achieve 5-channel output for mono signals, and can only output stereo signals. Therefore, it is likely that the audio output of the game only supports mono signals. Similarly, the audio driver can only  … View >>>

The computer motherboard integrates a sound card, and the Windows system is installed. It used to be normal, but recently, when playing music files on CD or hard disk, I found that only one speaker had sound - that is, only one channel had sound. This is still the case after changing a pair of speakers, while there is no problem with the motherboard and sound card.

This situation may be caused by the wrong setting of the "Wave" in the volume control, or a problem with the driver installation. First, double-click the small speaker icon in the desktop task tray to open the "Master Volume" dialog box, and check whether the "Balance" slider in the "Wave" is dragge … View >>>

It turned out that only one of the speakers had sound and the other had no sound. Later, the audio jacks of the two speakers were changed. Both speakers can produce sound, but one speaker plays normally, while the other has weaker sound. It plays normally while being connected to CD playback machine.

One speaker is normal but the other is weak. It may be caused by poor connection between the speaker cable and the audio interface, or improper waveform settings in Windows. First of all, you can check whether the speaker connection plug is in poor contact with the computer audio jack, or whether it … View >>>

Inkjet printers have printing actions when printing, and nozzles can move left and right, but they just can't print characters. What is the reason?

This phenomenon is usually caused by the nozzle, and the reasons are as follows:1. improper installation of the nozzle position makes the nozzle contact with the circuit board on the base badly, which causes the nozzle not to eject ink normally. The solution is to remove the printing nozzle and rein … View >>>
