[Bug 57936] Incorrect audio volume level read by app from the system - 100% all the time.

[WineHQ Bugzilla]

--- Comment #1 from Wiktor Grebla  ---
I tried to run Yousician with WINEDEBUG=+mmdevapi which showed me these:

02b4:trace:mmdevapi:AEV_GetMasterVolumeLevelScalar
(000000006D583FB0)->(000000006E4AEBA0)
02b4:fixme:mmdevapi:AEV_GetMasterVolumeLevelScalar stub

and this API I found in: wine/dlls/mmdevapi/audiovolume.c

static HRESULT WINAPI AEV_GetMasterVolumeLevelScalar(IAudioEndpointVolumeEx
*iface, float *level)
{
    TRACE("(%p)->(%p)\n", iface, level);
    if (!level)
        return E_POINTER;
    FIXME("stub\n");
    *level = 1.0;
    return S_OK;
}

So this stub is in fact returning 1.0 (100%).

Could this be modified to 0.8 upstream? :)

I don't want to re-compile wine on each update, alternatively I could hexedit
1.0f
to 0.8f, but I've problem finding correct dll, any hint?

Cheers,
W.
