Replaced the processor on the laptop. Lost sound. What to do?

Question

ubuntu

There is a computer hp pavilion dv6837er. Instead of hard sdd and in place of the drive -hard. Ubuntu on ssd, windows 8.1 on hard. Changed processor from T2390 to T7700. Everything starts up fine.
Lost sound on Ubuntu completely. In Windows, when I entered Skype, there was a sound, and I called to test the sound check in Skype, everything was there, and the microphone also worked. I saw in Windows that there are three undefined devices in the device manager, one turned out to update the drivers automatically, and the other two did not work.
Those two devices:
PCI\VEN_1180&DEV_0592&SUBSYS_30CC103C&REV_12\4&2C3A0EB7&0&4BF0
PCI\VEN_1180&DEV_0843&SUBSYS_30CC103C&REV_12\4&2C3A0EB7&0&4AF0
I found drivers for them - it turned out to be something related to the memory stick ... ricoh ... As a result, those undefined devices disappeared, but the sound on Skype also disappeared.
Now I don't know what they're doing. Maybe something is not connected somewhere on the motherboard? How can this be understood? Well, or badly connected, because the sound was to some extent?

Answer 1

Thought it was wood. Then I decided to unwind everything back, and it turned out that I didn’t connect the front panel with headphone and microphone inputs. All connected and earned.
