Yes, but non CX analog audio is better than nothing at all. Mono seems to fair better than stereo on older titles. The trick is to capture them on a older gas tube player like I have. Later models with digital sound aren’t so hot in the analog dept. Some models make it difficult to turn CX off on non encoded discs resulting in muffled sound.
VHS or Beta Hi Fi might be better, but finding a flawless tape is another hit or miss situation. When I captured a factory sealed VHS of Grease I still had audio dropouts to contend with.
