My early 2014 11" macbook air started running extremely slow and now the volume doesn’t work, even through headphones or bluetooth it still won’t work. I have tried: Connecting earbuds/ headphones/speakers via analog and bluetoothResetting the SDRAMResetting the SMC Whenever I toggle the sound it shows the speaker sign with a circle with a cross through it where you would usually see the sound bar. I have no idea why it’s running so slow, either. I have plenty of free storage and have ran antiviruses and that made it a little better, but not by much. I have not damaged or dropped it, and all this seemingly came out of nowhere about 6 months ago. UPDATE: The charging cable works, but the indicator does not shine on the charger anymore. Is my laptop slowly descending into !&&*? Should I just give up and build a PC?

Well I’m not sure building a PC from scratch is any better ;-} I think you likely need two parts here. Your I/O board has the DAC logic (sound) so it may need to be replaced. In addition the cable that interconnects the I/O board to the main logic board may need replacing as well.
