[EN] Audio lost when connect smartphone

When I USB connect my samsung smartphone in W8.1 Pro my audio is lost while Cross is running.
I do not think it is a Cross issue, as it just stops because the settingsinfo of the card driver is empty all of a sudden.
In Hardware I cannot see anything strange; no new soundcard is installed or some like that.
The phone is known by the system at the same USB port and does not have other issues.
Does any one have an idea what is going on, most of all how this can be avoided (while being able to connect...) and/or how this can be fixed without having to reboot the system.
Update
Tried with a different external soundcard, but issue is the same. All audio cards (both ASIO as WDM) are listed but do not work.
Upon disconnecting the WDM cards are back, but the ASIO do not work.
