I design broadcast video gear for a living. HDMI is an encrypted data stream, primarily video with the audio carried in small data bursts. The encryption is to prevent pristine digital copies from being made.

A decoder requires a big FPGA chip and then you also need the HDCP license to do the decryption which as a consumer you or I aren't going to get.
But there are very low cost converters from China that should work quite well. And as far as audio quality goes, you could upgrade the analog audio section of a cheap converter where quality matters. On the digital side either it decodes or it doesn't. Be warned though, this is micro surface mount territory, not those big old Pentodes in their spacious octal sockets!

BTW, HDMI is capable of carrying very high quality multi channel uncompressed PCM audio at 96khz. The payload of high quality audio is still minuscule compared to the video payload.
