Major issues with 0.8.3 bionic mate and PCIe

[TheSupercomputer]

I say hi to the community and want to start directly with the issues I have and could not solve myself.

If I try 0.8.3 bionic mate armhf from the newest as stable declared release from the ayufan repo the board will not boot.
The image was flashed with the newest etcher version on an 64GB emmc module.
If I install the version that's linked from the pine64 webpage (0.7.9 aarch) and manually upgrade to 0.8.3 (I know it's an aarch install instead of an armhf then) the board will boot, but both indication LEDs are on. (The white that's usually on and the red in addition)
Surprisingly video playback runs as smooth as never seen before on this board, YouTube runs, Twitch streams do not crash the whole browser but run also smooth but the sound sounds like some old cassettes that was played very often. (Sound through HDMI)

Usage of the PCIe Card with the SATA Ports directly from Pine64 doesn't work, the board won't even boot with it installed in the slot.
This PCIe problem is know for me since month and I hoped it will be fixed now.

I'm now at that point, to ask for any help. Board revision is 2.1 with 4GB now overclocking or some crude experiments in the past.
All what I what is: one 2TB NAS HDD, YouTube, Netflix and Twitch playback, plus some low resource intensive task like pihole, unifi controller and so on.
In previous versions (I think it was 0.6.9 the whole time because of many little issues) I was never able to get Twitchstreams or the PCIe Card to run properly.
Even a Minecraftserver was running on this board with amazing power, so I would really like it to see the Bugs fixed since everything else runs so great on this power full board, it's even faster as my old Computer.

I'm sorry for some bad English in this wall of text, it not my native language.
I hope for any help and will try everything that's maybe helpful. If some information is missing, pleas let me know and I will response as soon as possible.

I could obtain one additional maybe important information about the sound issue.
If a sound file (in my case a .wav file) is played over the terminal with aplay, then no sound issue is noticeable.

EDIT:
After installing ubuntu-restricted-extras, jackd qjackctl and pavucontroll sound works just fine, don't know what package does fix this issu, but aufter installing pavucontroll and setting hdmi as output sound is clear.

By default, sound goes to multi-channel SPDIF and HDMI. You have to manually switch that in sound settings to HDMI to have good quality.
