My PC is not detected AAC encoded format when connecting HDMI port it has support for DTS,DTS-HD etc. I didn't see AAC encoded format support for HSR41. Please see the attached image.

I think those in the pic are just the built-in decompressors, particularly for surround.
My point above was that the receiving device must have its own built-in AAC decompressor if it were to be able to utilize AAC coming into it.

Since AAC is embedded in MPEG-2, perhaps you could send it along as an MPEG-4 file, I suppose. The article below is not clear to me how MPEG-4 works with it. MP4 and 3GP formats are also mentioned.

Did you find any player can support AAC to play as bit stream or pass through?

No, but I wonder if renaming the file to .RAW would trick the player into sending it as a raw file? The other end should still see the headers in the stream and know it is AAC, I would suppose.

I tried simply rename .wav to .RAM file but it's not working as expected means still it has .wav extension only. Please let me know how can i simply rename to .RAW

I am sorry to have wasted your time. If it is not apparent by now, I should state it outright that I cannot help you. If AAC compressed files cannot be sent by any media player without decompressing it first into PCM, that must be a universal standard against which you are trying to act contrarily. Your last question completely baffled me concerning renaming a file to end in .raw being a puzzle to you. I give up.
I am declaring this effort of yours as an impossible one; futile, in fact. Good luck in your projects and good day.
