Hope someone out there can help with this, or has similar

issue.    Audio has stopped after upgrading my 1330 to 

Windows 10.  I was using an older version of Sigmatel which 

had worked well, and restored stereo mix.  Can someone point

me to a solution?    Thanks much . . .  UPDATE:   I tried to install the 

IDT driver for Windows 8.1, noted on another thread regarding another

laptop.  It seems to have restored my audio, but strangely I donn't see 

any note of IDT in Device Manager.  The Sigmatel driver, which was showing

as not working, is still there -- although I had to uninstall it to install the IDT

driver -- and now shows as working.....whatever works.   If anyone has any other 

thoughts on this subject, much appreciated...
