# Sound Card Issues with Software Updates

## post by cwright on Aug 27, 2021

Hi Everyone,

I have been having some issues with sound on my Tensorbook and think I have traced the issue to Nvidia Driver updates. The problems started about 3 months ago when the A2DP option quit working for all of my Bluetooth headphones. The sound only worked in mono/stereo. I tried everything I can find on every linux/nvidia/stackoverflow forum with no success. Yesterday I updated to Nvidia - 470 drivers and I have no sound at all for my headphones, and the sound from the computer speakers has so much static and echo that it's impossible to understand what is coming out. Anyone else having this issue? The only thing I think I have left to do is buy a new sound card.

Edit: After writing this, I found this link [https://help.ubuntu.com/community/SoundTroubleshootingProcedure](https://help.ubuntu.com/community/SoundTroubleshootingProcedure) on the lambda stack forum and it completely fixed the problem…
