no sound in Qemu 4.0.0 with AC97 and ES1370 soundcards, despite the use of correct drivers

      QEMU 4.0.0, AC'97, ES1370



      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 :


      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 a 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.
