    Description: High Definition Audio Controller

    Manufacturer: Microsoft

This showed sound card is causing the problem, but this one in fact is not the sound card(realtek in my case). The culprit is "Intel(R) Display Audio" in Device Manager - Sound video and game controllers.

As of 2023, update Intel graphic card drivers did not solve the issue. 

Disable this "Intel(R) Display Audio" would solve the problem. It is used by hdmi / direct Wifi to allow tv to play sound.

trim mp3 files using ffmpeg, works for video too

ffprobe.exe to get duration of MP3 in number of seconds.
   ffprobe  -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 file.mp3

ffmpeg.exe to trim away first 8 seconds, end at 999 seconds of All mp3 files in the working folder.
  ffmpeg.exe -ss 8 -t   999  -i input.mp3 -acodec copy output.mp3

Trim from 00:02:54.583 to end of file:
 ffmpeg  -ss 00:02:54.583 -i input.mp3 -acodec copy output.mp3

Works for video too:
ffmpeg -ss [start] -i in.mp4 -t [duration] -c copy out.mp4
ffmpeg -ss [start] -i in.mp4 -t [duration] -c:v libx264 -c:a aac -strict experimental -b:a 128k out.mp4


C:\ffmpeg Folder\mp3files\go.bat

echo "==========" > done.txt
for %%f in (*.mp3) do  (
    echo|set /p="..\ffmpeg.exe                         %%f                           " >> done.txt   
  ..\ffprobe  -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1  %%f  >> done.txt
)
rem Open done.txt in Excel, deduct 18 from the -t seconds     

rem (objective is to cut first 8 seconds, trim last 10 seconds of each mp3) 

rem use =concate() to reconstruct the command list, to put to new.bat
rem rearrange param, -ss and -t must precede -i
