Radio Problem

[Pod562 0]

The other evening, I was enroute to Zurich in the PMDG 737-800 and was tuned to Unicom on Com 1. I decided to listen to Swiss Radar on Com 2 as I was due to enter into Swiss airspace in half an hour.When entering Swiss airspace, I turned off Com 2 on the radio Stack and retuned Com 1 to Swiss radar. I was then handed off to Zurich Approah but when I tuned com 1 to Zurich Approach, I found that Com 2 was still receiving Swiss Radar. I checked the Radio stack and the Com 2 light was definitely out.Having two people speak simultaneouly made life very difficult, especially as I find understanding ATC instructions a struggle sometimes anyway and the problem persisted when handed off to Tower and Ground. This is the second time this has happened to me and therefore I am reluctant to use Com 2 now.Anyone ever had similar problem or am I doing something wrong as usual.CheersRenzo
