Thanks for the data @stagren .
Actually, from the logs I see no reason why sound should not come out. The driver is setup to stream out to your Realtek Hoegtalare device, which is the loudspeaker, I presume.
Leaves the question, how is Windows configured with you? There is also a Windows setting, allowing applications exclusive access to sound device. This setting should be switched off. Have a look at athis thread where I outlined what you need to do. Only exception, don’t choose the headphone but the loudspeaker device. The rest is identical. Once you’ve changed the setting, restart all applications and see how it goes then.
