Envy Phoenix 860-014
Microsoft Windows 10 (64-bit)

Have an HP Envy Phoenix 860-014 connected to an HP TV/monitor with HP Z34c-4 (NVIDIA High Definition Audio) speakers that quit working. Sound playback window shows the fluctuating green sound level bars. I haven't found any way to troubleshoot these speakers. I had a similar problem lastweek on another desktop and was given a link to download an "sp" file that fixed the problem. Is that the answer here or is there something else I need to try?
