Original sound is a 48Khz Ac3 2.0
The default aac encoder supports AA-LC only, unfortunately it is not possible to encode to HE-AAC or HE-AACv2.
--audio-profile options is for other encoders such as libfdk_aac which can actually use HE-AAC or HE-AACv2. However, it is not included in my build, as it is not allowed to distribute in binary due to it's license conflict with (L)GPL.
Dunno if it could be useful in any way, but there's exhale too:
ecodis extended high-efficiency and low-complexity encoder - an open-source ISO/IEC 23003-3 (USAC, Extended HE-AAC) encoder
https://gitlab.com/ecodis/exhale
According to the git, the license is
based on the 3-clause BSD license but modified to address particular aspects dictated by the nature and the output of this application

Hope that helps.
@rigaya : Is there a tutorial how to build it with libfdk_aac ? I can only find the standard description
@forart : exhale is nice, but my appletv can't play it directly

Is there a tutorial how to build it with libfdk_aac ?
No tutorial will be provided for a custom build.
@rigaya I do respect that, but wouldn't it then help to state it somewhere, that this is not working or to remove the options to save people time trying it out and failing ?
The option will not be removed, as this option was actually added by request from others who as actually made their custom build themselves.
Now QSVEnc 7.34 will show following warning for clarification.
avout: codec aac (audio track 1) does not have profile choice, profile settings to 4 (HE-AAC) will be ignored and default profile will be used.
Version 7.29 : Windows
When Trying to encode sound as AAC-HE, I end up with a corrupted file that is not playable, and MKVToonix says, the "Malformed AAC codec initalization data found"
parameters are "--audio-codec aac --audio-bitrate 64 --audio-profile HE-AACv2 when using HE-AAC the same happens
this is what mediainfo says about the sound
