What difference does it make what I do? I own two digital multimeters with continuity test functions that produce an audible beep or tone. One is a BK Test Bench 390 handheld multimeter and the other is a Fluke Dual Display Bench-top Multimeter.
Just because you have no use for an audible continuity test function doesn't mean that others don't use it. As I mentioned before, if you have a number of continuity tests to make, the audible tone saves time. For example, suppose you have a bunch of cables to test for continuity. You can speed up the process when you don't have to continually look at the meter's display instead of simply listening for a tone or beep. If you don't get a tone, you can set that cable aside for further inspection.
I was also an electronic technician before becoming a mechanical engineer. I've been using electronic test equipment since I was 20-years old and I'm now 76. I've also been an audiophile for the same length of time, and I've done a lot of testing on my own audio equipment. Moreover, I was a PMEL technician in the Air Force where I calibrated and repaired oscilloscopes, meters, and signal generators. Then the Air Force sent me to school in mechanical engineering at the University of Arizona where I received my BSME degree and was subsequently commissioned a second lieutenant. I worked as an aircraft/nuclear weapon integration engineer until I was promoted to captain and transferred to the B-2 Stealth Bomber Development Program. I later retired from the Air Force with 23-years of service.
Here's a picture of some of the electronic equipment I own today.

Ok fine and fair enough. I never questioned YOUR experience. Yes continuity is OK for a quick cable check, but is an outdated test procedure nonetheless. Continuity in an electrical circuit proves nothing as far as diagnostics go. And that is where we are at with the original poster's question. "perfect" continuity and even "perfect" circuit resistance still leaves a lot of unanswered questions about circuit integrity.
The whole point in my initial answer before you horned in with that "lack of experience" nonsense was to let the OP know that continuity testing is not going to diagnose the concern. I would START with some resistance readings. And then move to ckts shorted together or to ground somewhere. Then lastly move on to checking the ability of the ckt(s) to carry amperage.

How much amperage do you think those phono cables need to carry? LoL
