This is definitely not normal and should be diagnosed and fixed.
Start by making sure your firmware is up to date. In Setup > Device Setup > Firmware Information, compare the version numbers for all 3 parts of the firmware (Main, Loader, Sub/MCU) against the expected values as shown on the OPPO support page or in the firmware history portion of the first post of the BDP-93 sticky thread at the top of this forum.
Whenever the player exhibits odd behavior, a good thing to try is a simple reset:
1) Remove any disc. Jot down your personal settings.
2) In Setup, Erase Persistent Storage, and then Reset Factory Defaults. When the Easy Setup Wizard finishes, power down the player -- NORMALLY, not by cutting it's wall power.
3) NOW remove wall power from the player for about 10 seconds. Do not skip this step.
4) Power up, and re-enter your personal settings.
5) Power down the player again -- normally. Settings are saved during the power down cycle.
If you are using HDMI for audio when playing the SACDs then you could be having a form of HDMI handshake failure. The next time it happens, turn volume WAY down on your AVR immediately and then take a careful look at what format of audio signal your AVR is reporting as input. Compare to what it reports when the SACD playback is correct. If you are getting an incorrect signal type reported then the usual sorts of steps for addressing HDMI handshake problems apply. E.g., checking your cable quality.
Another step to try with digital audio output is to Pause the player and then Play again. This makes the AVR re-sync with the digital audio input stream and can cure problems where the AVR failed to recognize the start of digital audio properly.
If you are using Analog for audio when playing SACDs, then obviously that does not apply. If it is happening on more than one disc, then your player likely needs service. Talk to OPPO and let them help you diagnose this.
By the way, cutting power to the unit by turning off the power conditioner should *NOT* be your normal way of shutting it down. The player should be allowed to power itself down. Suddenly cutting off wall power prevents the player from saving settings. It is also not a good thing to do while a disc is playing.
