When trying to start the VM with an audio driver enabled, got a trap in VBoxDD.dll (src\VBox\Devices\Audio\DrvAudio?.cpp, line 1797, function drvAudioDestruct()):

        pThis->pHostDrvAudio->pfnControlIn(pThis->pHostDrvAudio, pHstStrmIn, PDMAUDIOSTREAMCMD_DISABLE);
        pThis->pHostDrvAudio->pfnFiniIn(pThis->pHostDrvAudio, pHstStrmIn);
    }

    if (pThis->pHostDrvAudio->pfnShutdown) // << ==== Access violation
        pThis->pHostDrvAudio->pfnShutdown(pThis->pHostDrvAudio);

    LogFlowFuncLeave();
}

This is because of pThis->pHostDrvAudio == NULL, then trying to dereference this pointer, without a check for validness.

This is after the drvAudioConstruct() failed in PDMDrvHlpAttach():

    /*
     * Attach driver below and query its connector interface.
     */
    PPDMIBASE pDownBase;
    int rc = PDMDrvHlpAttach(pDrvIns, fFlags, &pDownBase);
    if (RT_FAILURE(rc))
    {
        LogRel(("Audio: Failed to attach to driver %p below (flags=0x%x), rc=%Rrc\n",
                pDrvIns, fFlags, rc));
        return rc;
    }

The log piece:

The call stack:

 vmR3CreateU(UVM*, unsigned, int (*)(UVM*, VM*, void*), void*)
 vmR3InitRing3(VM*, UVM*)
 PDMR3Init
 pdmR3DevInit
 hdaConstruct(PDMDEVINS*, int, CFGMNODE*)
 hdaAttach(PDMDEVINS*, unsigned, unsigned)
 pdmR3DevHlp_DriverAttach(PDMDEVINS*, unsigned, PDMIBASE*, PDMIBASE**, char
 pdmR3DrvInstantiate
 pdmR3DrvDestroyChain
 drvAudioDestruct(PDMDRVINS*)

The driver appears to be MMPM2 (not sure if it is fully implemented, so disabled for now, then got the following error in the next ticket #18)

When enabled the network (namely, the NAT), got a lot of messages in the VM log about incorrect return from poll() (a log can grow up to tens of megabytes):

00:00:50.680202 Changing the VM state from 'CREATED' to 'POWERING_ON'
00:00:50.704983 NAT: Poll returns (Invalid argument) suppressed 130

00:00:50.706103 NAT: Poll returns (Invalid argument) suppressed 130
00:00:50.706319 NAT: Poll returns (Invalid argument) suppressed 130

The poll() emulation on top of select() is taken from *BSD.
