The computer sounds abnormal, can be handled by the following way
First, check whether the latest sound card driver is installed.
Second, the quality of the speakers may be problematic. Lower-quality speakers tend to be more prone to distortion than higher-quality speakers in the bass. If the quality of the speakers is low, only hardware upgrades will improve the playback effect.
Third, the sound distortion may be because the volume sent to the speakers is too high to exceed the processing range of the speakers, you should try to reduce the volume sent to the speakers.
Check that the "Use single mode DMA" setting is correct. Check that the Use single mode DMA setting is turned on:
1. Click Start, point to Settings, click Control Panel, and then double-click System.
2. On the Device Manager tab, double-click Sound, video, and game controllers, and then double-click the sound card. If you do not know the sound card name, consult your sound card documentation.
3. Click Properties, and then click the Settings tab. Click Advanced Settings, and then click to select the Use single mode DMA check box. If the Advanced Settings button does not appear on the Settings tab, the sound card does not support this feature. Click OK continuously, return to Control Panel, and then close Control Panel.
Five, there may be a hardware device conflict on the computer. Check to see if the device is included in the Device Manager tab and there is no conflict. Click Start, point to Settings, click Control Panel, and then double-click System. On the Device Manager tab, check to see if the device appears and there is no yellow circle with an exclamation point next to the device. If a yellow circle with an exclamation mark appears next to the device, the device may use the same settings as other devices in the computer. If you find a yellow circle with an exclamation point: Double click the device, and then click the Resources tab. Look for a resource conflict in the conflicting devices list. If there is a resource conflict, reconfigure a (some) device so that it uses different resources to eliminate the conflict.
