According to my humble opinion the OSS port does not work correctly with a make.conf with different .if .then parts.
This or i have a syntax error in my make.conf , and make does not really care about syntax .
Or there is a problem with the use of python3.9

On a quick glance, looks like in-kernel API changes. Did you check it actually builds fine on the official builders?

As FreeBSD's own dsp devices are compatible with OSS, do you really need this software?
 
I wanted to avoid PULSEAUDIO so i started using OSS.
I have only one port really dependend on it : qmmp-qt5-1.5.2.

Well, as I said, FreeBSD's dsp devices implement OSS, so normally, there's no need for additional software ...

I have only one port really dependend on it : qmmp-qt5-1.5.2.
Uh, this one has strange option defaults:
Code:
     OSS=off: Open Sound System support
     OSS4=on: Open Sound System (ver4) support

I wonder whether there's any sane reason for it. Instead of installing additional software, I'd first try to disable OSS4 and enable OSS instead.
 
Same crappy problem here.

I have an ALC887 soundchip and this is beautiful: all the plugs are shown with their proper colors and are configurable and have little faders attached, no need to work with nids and mixer.
Now I'm using a board with VIA chip, and this is only understood as default HDA, no individual colors etc. So preference may depend on the actual soundchip.
But then, recently, when somebody upgraded the jack port to jack-2, they botched it, and it does no longer work properly.
Nevertheless I keep it to compile, as maybe I switch back to the other board, or maybe I don't use jack anymore, or maybe I find a way to fix or workaround it.

This should solve it. But, as I'm not currently using it, I don't know if it will work - only that it compiles now.

Wasn't easy to find. The "incompatible pointer type" is the root cause.

Normally, with such an error, we look at what is pointed at - and if that is the same, it is just a rename, and we can adjust accordingly. And normally we can search for the name with something like find /usr/include /usr/src/sys/sys -name "*.h" | xargs grep name, and we should get (a lot of references and) somewhere the original definition of the thing (or a definition that references another name, etc.etc. and finally the original definition).

But not in this case. The original definition isn't present, only the pointer is used. And the name has changed, that is obvious when looking at device (9) for 12.3 and 13.1.
I finally found the original definition, not in a header file, but in subr_bus.c (not sure if it appears elsewhere also). It seems that definition is intended be kept internal to whatever bus maintenance stuff (it is also a good way to make sure nobody understands the code).

Anyway, the structure definition itself is not different betwenn 12.3 and 13.1. So it is just a matter of adjusting the name in the audio/oss. And then I found, this had already been done, but for Rel.14, not for 13.
