No sound in QEMU 4.0.0 with AC97 and ES1370 soundcards, despite the use of correct drivers

Hello,

I use ReactOS 0.4.11 with QEMU 4.0.0 (last version), on a linux host (archlinux 64 bits),

I notice a bug related to soundcard, when I select "ac97" as soundcard in qemu then it's impossible to get sound, even if I install the AC97 virtualbox driver (provided in ReactOS applications manager),

I followed the wiki instructions for configuring soundcard running ReactOS in qemu :

https://reactos.org/wiki/QEMU

If I install the VirtualBox driver (advance AC97) the driver is installed but I get no sound, the audio mixer shows no audio device, and after 3 reboot ReactOS freezes at startup, just before displaying the desktop,

I discover that qemu emulates "Intel 82801AA AC'97" soundcard when setting "-soundhw AC97", so it's not the advance realtek version, the virtualbox AC97 driver may not be suitable,

In Windows XP qemu virtual machine I can see "Intel 82801AA AC'97" description in device manager, I tried to extract the driver from this virtual machine : ac97intc.sys and wdma_int.inf files, they can be installed in ReactOS manually, but I still get an error, the mixer audio is showed but there is no audio devices listed, and I get no sound, and ReactOS will freeze after 3 reboots,

I tried also ES1370 soundcard with the appropriate driver (downloaded from creative website) but I get no sound, and I have also a freeze after 3 reboots,

I think there is a bug in ReactOS related to soundcard and audio mixer when using qemu, you can find as attached file a bash script for recreating qemu virtual machine for ReactOS, and the "Intel 82801AA AC97" driver extracted from a windows xp qemu virtual machine.

Thanks
