RPi-3 SNES-9X Next Audio Lag?

[Shockwave]

Specs: R-Pi 3, Model B, running RetroPie, Ver. 4.0.2, updated yesterday, 8/30/2016. Micro SD: 128 GB Sandisk Ultra, Class 10, UHS-1. ROMs in question: Street Fighter 2 Turbo.sms and Super Castlevania 4.sms, unzipped. Controller: Dual Shock 3 connected via USB (wired). USB keyboard connected. Wi-Fi enabled.

Problem: I noticed that whenever I put in the command on my DS3 to move through menus and moves for my characters on screen, that the game's audio would be about 1-2 seconds behind the action on screen. It's as if the audio was lagging behind the action and graphics on screen. It did not affect the gameplay, but might have been a bug in the implementation of the core for the overall structure, or something on my end that I may need to configure, which is why I'm posting it here asking for help. I do believe this problem did not occur on the previous build of 3.8.7 (my 4.0 crashed on me when loading ROMs and ISOs from the USB thumb drive when 4.0.2. came out, so I updated straight away). I haven't tried other cores on the Retroarch command line yet, but wanted to put this out there to see if anyone else is experiencing this.

Some other things I noticed when I booted up the Pi 3 tonight and additional information and corrections:

1. Upgraded form 3.8.1, not 3.8.7 (sorry about that).
2. Burned from my PC using Win32DiskImager.
3. It's happening on ALL of the emulators, not just SNES, and I tried NES (Contra, Mega Man 2, Castlevania 3: Dracula's Curse, Super Mario Bros. 3), Genesis (Sonic the Hedgehog, Earthworm Jim, Mortal Kombat), 32X (Virtua Racing Deluxe), Sega CD (Snatcher), and PSX (Crash Bandicoot, Castlevania, SOTN, and Tekken 3). Same audio lag by about 1-2 seconds after the motion. Music also lags behind, but it's harder to catch because of the input from the sound effects.
4. Just to make sure it wasn't the R-Pi 3 in question, I had another Pi-3 with another SD card running a different software on it and removed the SD card from it and stuck the same 128 GB SD card inside the R-PI 3 and powered it on (using Canakit parts from one of their many R-Pi 3 kits they sell on Amazon with the 2.5 A, 5 V power supply). and same problems occurred.
5. The garbled sound in the main menu for selecting games and lags behind in the moving of the highlighter from game to game (sounds like static), and even through selecting consoles in the main menu. Also, I notice when the R-Pi 3 is powered down, either through the Emulation Station shutdown procedure, or by the In-Line Power Switch I have connected to function as an on/off switch for the R-Pi 3, the sound volume always goes back to 0% when I power on the unit.

Just my takes on the situation. Anyone else notice this?
