Call audio too low

Replaced my LCD and digitizer (cracked). After reassembly, the received audio from the upper speaker was low and scratchy. I cleaned it, it got only a little better. Volume buttons don't help. If I use headphones, bluetooth, I can hear fine, volume buttons work on those.

If I turn on the call to the speakerphone, the volume is loud, but the other party stops hearing me. This is a different set of symptoms from other similar call audio problems on your site.

I may have pulled the ribbon cable on the headphone jack.

I assume the headphone jack needs replacing, but I wanted to see if I need something else because of the way the speakerphone option is acting.

Thanks in advance,
