Trouble with music from laptop need help

polk500

So what been happening is I will be listening to music say from Spotify using spoiify connect from the ipad and them decide to listen to something using jriver, I will switch over to jriver select an song and no sound!!

I will open up the CA usb 2 sound card see that indeed it's working but no sound.
Look at the difference setting for the sound card everything seems correct,restarted the laptop and sound,great or so I thought.
Switch over from watching a movie to laptop no sound again.

So list of gear that could be the problem?
AVR Yammy 2040, with the other AVR never had this problem but because when I restart the laptop I get sound so I don't think the AVR is the problem.
Dac Magic 100 uninstalled / reinstalled driver, never made any difference.
jriver software seems to work fine.
HP 6500 note book running windows 7 professional, must be the problem but can't seem to be able to identify what causing this no sound issue.

Any help or suggestions would be appreciated.

Thanks
Roger

Well done some reading online and I uninstalled / reinstalled the difference sound codex's and everything seems to be well.

Apparently the problem was with Spotify as a banner popped up and said there was something wrong with the sound card.

Alls well.
