Why is sound from internal speakers clear but "staticky"?
I have sound from both speakers. If the volume is low, it is almost as if both speakers work with no sound distortion. However, as I raise the volume, so increases the staticky, fuzzy sound, that is like a blanket has been placed over the sound output. My computer chimes, and makes all alert tones, just not clearly if coming directly from the internal speakers.
On the other hand, I have clear sound with no distortion from my headphone port, and via bluetooth connection.
Here is what I have done:
Several Pram and SMC Resets over time.
I upgraded from Mountain Lion (hungry memory eater), to the more stable El Capitan.
I have a subscription to CrashPlan, a bootable usb stick, and now a recovery partition.
I purchased a new battery.
I have 8 Gbs of Memory, but it is DIMM0 DDR3 1067 MHz (needs upgrade).
Hard Drive passes tests with flying colors but it old nonetheless.
I only use about 45GB of a 500 GB SATA Hard drive, and farm out all the data to 5 USB drives.
When I use my VPN, the computer fans run almost the entire time, despite keeping it on a Rain Design iLap, and turning ANYTHING else off I can. The fans stop when the computer is not on my VPN.
This trouble began (I'm pretty sure, but not 100% sure), when I linked up with JVC Flip2 Speaker. I was not able to get it to connect to bluetooth as I had before, so I also connected the speaker to my computer headphone port with a male to male audio jack cable. About a week or two later, the audio from the internal speakers was too fuzzy to listen to without earbuds. I've been making do this way for over a year, while looking everyplace I could for some sort of answer, other than the Apple Store. I do not know if it is a settings/preferences issue (I have emptied the audio cache a few times), or if the connection then disconnection of the two audio nodes left the internal speaker in its present state.
There is little to nothing out there regarding speakers that still have sound, just bad sound. I have also pulled up the MIDI Utility and tested the speakers on different channels. Both have output regardless of the channel (1 or 2), to which they are connected. I have not been able to find anything like this, and when I do find information that may apply, it is in Developer-Speak, which may as well be in Klingon.
I cannot find what the settings /preferences are supposed to be, and I have gone through every Core Audio-related setting/preference, Googled it, and come up with nothing.
The current output sample rate is 44100. I have never asked a question before for a forum so please forgive me if I left something important out, or said too much.
Is this a good question?
