I have an HP Beats Laptop, and changed the amount of bass in the settings. Once i had saved the changes it told me that my souncard had stopped working. I reverted the changes to no avail and then just quit and resrarted the program and it worked.
I have a Dell and did the same thing with the bass. Then Spotify tells me I have a sound card issue. I went back and cahnged it to original setting & still have a notice of soundcard problems? Help anyone?
Here is how I fixed the problem with my Dell laptop:
Go to Control Panel and navigate your way to Device Manager.
Expand Sound, Video and game controllers.
My problem was with the IDT High Definition Audio CODEC. (Yours may be another device name.) Even though the driver was up to date and the card works fine for other things (such as pandora), I had to unistall the device.
Right click your device and click Uninstall. Click OK when it asks you if you are sure.
Now right click on the Sound, video and game controllers label and click 'scan for hardware changes'. It should detect your hardware and automatically install the drivers.
If you have trouble re-installing your drivers, go to your computer manufacturers website and download the drivers and install them that way.
I just had this same exact problem yesterday. I was trying to use my surround sound instead of my bose speakers and so I had to disable my bose speakers. By doing this I had to go to Control Panel>>Sound (May be different for users using other than Windows 7) This brings up all the possible devices to play music from. I had to plug in my surround sound to the audio jack in the front of my desktop. So what I did is I disabled the speakers, an set the audio jack/headphones to default audio device. Now when I was done using my surround sound, I wanted my speakers to be set as default again. So I set them to default, an I tried using spotify an it wouldnt work. I restarted the program an nada. After messing around with it a bit, I eventually just left my speakers set as default an restarted my whole computer which always helps in situations like this. An it worked perfectly. I would suggest others to make sure their wanted audio device to be set as default and restart the computer! As well as drivers an all windows updates are installed. All of these could be major issues to why your sound is not working with spotify.
Hope this helps if none of this wasnt already stated, I didnt exactly read all the replies.
I can understand how surround might throw off the program, but my soundcard is just stereo. I can only think that Spotify just isn't compatible with the soundcard I use. Does anyone know of a list of soundcards which are incompatible with Spotify?
