 Thank David for your advice!

i think tv audio is stereo, connecting to mic instead of linein may result in poor quality
but i'm not professional artist, i can't tell difference most time
but for really good tv program, i will use linein

I would expect personal computer sound card line-in and microphone 
inputs to use the same design analog-to-digital converter.  So, the 
sampling rates and bit depths should be the same.


But, microphone inputs are usually monaural. So, if you use a stereo 
patch cable from your television to your computer, you will only hear 
the left channel.


And, microphone inputs usually have more analog gain. So, you will need 
to turn the television volume down and/or reduce the microphone gain in 
your mixer application.  Either can reduce the signal quality.  Failure 
to do so will result in clipping.


You will get the best recording if you connect the television line-out 
to the computer line-in and match the signal levels.
