In case of sound devices which are created by default (some of them even with
-nodefaults) it would not be nice to users if qemu required explicit:
-audiodev driver=none,id=audio0 -machine audiodev=audio0
when they just want to run a VM and not care about any audio output. Instead
this little helper makes it easy to create a dummy audiodev (driver=none) in
case there is no audiodev specified for the machine. To make sure users
are not surprised by no sound output a helping message is also printed out.

Many machine types have default audio devices with no way to set the underlying
audiodev. Instead of adding an option for each and every one of them, this new
property can be used as a default during machine initialisation when creating
such devices.

For machines with an embedded audio device, "-audio BACKEND" will
set the audiodev property of the machine itself.

This hunk has nothing to do with vt82686 so probably should be in
previoius patch. Also sam460ex embedded sound part is not emulated and can
only use PCI sound cards. What this line is needed for? If every machine
now needs this call, can it be added in some generic machine init func in
hw/core/machine.c instead?
I'm not sure about this whole series. Looks like it gets rid of 71 lines
but adding 158 and makes the users' life harder by requireing them to
specify drivers they may not even know about. What's the point? Is there
still a default to use the normally used audiodev for the platform or
people will now get errors and no sound unless they change their command
lines?

No, this line shouldn't be there.

It is not needed by every machine, only by every machine that has
embedded sound.

I think you're right, I should have sent this series without the last
two patches.
The first seven add more functionality, because they let you use
-audiodev for configuration of embedded boards. This is why they add
some lines of code.
The last two patches instead are the ones that make -audio or
-audiodev mandatory. They should be separate and they may not be a
good idea without something like "-audio default". And if no "-audio
default" is added, there is more code that can go (for example the
--audio-drv-list option to configure and CONFIG_AUDIO_DRIVERS).

I still don't see the point, because it already works without these
changes. With current master one can specify -audiodev for -M paegasos2
and it gives a warning but does the right thing and sets the audiodev for
via-ac97. I think the warning can be avoided by using -global to set the
via-ac97 audiodev property but since it picks up the -audiodev there's no
need to. Apart from the warning this is convenient for the user, what's
proposed in this series seems less so. What is the issue this series tries
to solve?

This is necessary for the q35 configuration tests to pass,
once audiodev becomes mandatory.

Now that all callers support error reporting with errp and all machine-default
devices use an explicit audiodev, this can be changed. To make the detection
easier make AUD_register_card() return false on error.

Now that audiodev= is required and audio_init() will not be called

out in case audio drivers fail initialisation or when the driver does
not exist.
