Reasons why MIDI music does not sound

I have been listening to songs in MP3 and WMV formats, and I have not found any clues. Today I want to get some mid music and put it in my smartphone. I want to try it out, but I suddenly found out how my Little T could play the mid and get bored. Why?

Reinstall the system? That's too much trouble, so find a solution. After searching online, the system is reinstalled, the sound card driver is reinstalled, and the driver is reinstalled several times. Is it because Microsoft updated the latest DirectX version in July? I want to uninstall DirectX and try again. At this moment, I saw an article using the registry method, which is relatively simple and reliable.

Copy the following two legendary split lines and import them to the Registry.

 

========================================

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE/software/Microsoft/Windows NT/CurrentVersion/drivers32]
"Vidc. mrle" = "msrle32.dll"
"Vidc. msvc" = "msvidc32.dll"
"Msacm. imaadpcm" = "imaadp32.acm"
"Msacm. msg711" = "msg711.acm"
"Msacm. msgsm610" = "msgsm32.acm"
"Msacm. msadpcm" = "msadp32.acm"
"Midimapper" = "midimap. dll"
"Wavemapper" = "msacm32.drv"
"Vidc. uyvy" = "msyuv. dll"
"Vidc. yuy2" = "msyuv. dll"
"Vidc. yvyu" = "msyuv. dll"
"Vidc. iyuv" = "iyuv_32.dll"
"Vidc. i420" = "iyuv_32.dll"
"Vidc. yvu9" = "tsbyuv. dll"
"Msacm. l3acm" = "l3codecp. ACM"
"Vidc. cvid" = "iccvid. dll"
"Wave" = "wdmaud. DRV"
"Midi" = "wdmaud. DRV"
"Mixer" = "wdmaud. DRV"
"Aux" = "wdmaud. DRV"
"Vidc. vmnc" = "vmnc. dll"
"Vidc. acdv" = "acdv. dll"
"Msvideo8" = "vfwwdm32.dll"
"Msacm. tssoft32" = "tssoft32.acm"
"Msacm. sl_anet" = "sl_anet.acm"
"Msacm. divxa32" = "divxa32.acm"
"Msacm. Vorbis" = "Vorbis. ACM"
"Vidc. XviD" = "xvidvfw. dll"
"Vidc. ffds" = "ff_vf1_dll"
"Vidc. wmv3" = "wmv9vcm. dll"
"Vidc. TSCC" = "tsccvid. dll"

========================================

 

Final reason:

I used an optimization software to clear the junk files generated by the Compilation Program, and then clicked another option. He deleted some sound registry keys and re-imported them to the Registry.
