I use a Dell laptop with BIAB; it's 2-3 years old, running Windows 7, and the latest build of BIAB 2015. I don't use this computer for any other purpose but music; I do use the Chrome browser occasionally just to listen to YouTube music to help me with programming songs in BIAB. No external midi hardware, just BIAB, using mostly RealTracks. No issues with the program - that I know of. But there is a mysterious problem I would like to solve and I hope someone on this wonderful forum can help me.

I leave this laptop set up on stage in my place of worship all the time, hooked up to the PA, and I have had the same routine for several years. Early each week I select and tweak the songs I am going to use the following weekend and save the set which I will play using the Jukebox. Then during the praise & worship, I repeat the set as planned. Again, no problem with BIAB - that I know of.

Here is the mysterious problem that only began a few months ago, maybe a year ago at the most. Every time I turn on the computer and the sound system and, after giving the laptop plenty of time to boot up and open BIAB, when I start a BIAB song (any song), I hear no sound whatsover. BIAB is playing the song and the cursor is moving through the chord chart, but there is no output to the mixer. The laptop's headphone jack is connected to the mixer, but there is no signal coming out - until I disconnect the cable from the headphone jack, then start a song with it disconnected, and then reconnect the cable to the headphone jack after it begins playing through the dinky little laptop speakers. When I do this procedure, it works every time and it will then work normally for the rest of the session, but I didn't always have to do that. It used to just work without having to disconnect and reconnect the cable.

I suspect it may be a Windows issue that began after a Windows update, but I have checked all the settings and just cannot figure this one out. Any ideas?

Thanks in advance,
Jim
