Wil Initial turbo speedup bootprocess when underclock RP

[MrHifiTunes]

I noticed that RPi4 doestnt have HW acceleration to decode FLAC.  Is this normal? 

I'm not sure what you are referring to. I wasn't aware that any CPU or SBC supported the FLAC codec algorithms directly. The RPi's ARM CPU does have a hardware floating point unit.

By design, the FLAC decoding algorithm is fast even on slow machines.

As a newby I have no clue myself but I came across 
https://www.raspberrypi.org/documentatio...cgencmd.md

codec_enabled [type]

Reports whether the specified CODEC type is enabled. Possible options for type are AGIF, FLAC, H263, H264, MJPA, MJPB, MJPG, MPG2, MPG4, MVC0, PCM, THRA, VORB, VP6, VP8, WMV9, WVC1. Those highlighted currently require a paid for licence (see the FAQ for more info), except on the Pi4, where these hardware codecs are disabled in preference to software decoding, which requires no licence. Note that because the H265 HW block on the Raspberry Pi4 is not part of the VideoCore GPU, its status is not accessed via this command.
