Hi Admin,
to play music in the room without microphone it doesn’t have to be special sound card. i believe most of the pc can play. all you need to go is 1.doulbe click on the speaker on the lower right hand corner 2. control volume will pop up from there click on option select properties 3. now there’s two 2 option for you to select just select recording now look for stereo mixer or wave out mix then click ok. 3. now recording control window should show up from there you would select stereo mixer or wave out mix. Notice you only have one to select. this will play anthing from your pc thru the room but of course you have to lock the mic in the room. lol.
if you want to talk on the mic just go unmute your mic from control volume or just double click on the speaker again control volume will pop up. it’s look confusing but once you done it. it will be easy. lolzzzzz
