Most likely the driver has been corrupted.  There are numerous (over one hundred) versions of DV7 so i can't point you directly to the correct driver since you haven't mentioned the exact model and the OS you are using.  Uninstall it, run a system maintenance soft like CCleaner, reboot and when the New Hardware wizard opens, let it automatically search and install  it.

How to turn on the speakers on an HP Pavillion dv7 laptop


Go to your control panel and click the "find and fix problems2 link under SYSTEM and SECURITY then select the trouble shoot audio playback. Click next wait for it to search then select speakers and click next this should fix your issue.
Alternatively the volume setting for one or more sound devices might be disabled or set too low. There are separate sound controls for the hardware devices (speakers / head sets) and the individual applications (Windows sound / QuickPlay / Windows Media Player). For example, if the speaker is turned on, but the application is muted, you will not hear any sound. open the sound volume mixer and check the different settings

If you have checked all functions as you described and a remote monitor, then the problem is the graphics card on the motherboard, in most cases the motherboard must be changed because the graphics card is built in.

Your laptop still not charge even with the battery removed?
I guess you need a new adapter. Or you can test with a known working adapter first.

it sounds like the SD card reader has failed. This fortunately is a quick, semi-cheap (~$20) fix. You can purchase a media card reader that plugs into the USB on your system for about 20. If your system is in warranty, I would contact and see if they could schedule a replacement part or a depot fix/tech call to replace the failed drive
