If you search YouTube and browse the various videos related to "DSO138" you will see that this is quite a capable device in the audio range - up to about 20kHz.
I've just bought myself one, and hope to resurrect my televisor sometime in the near future, using this as a diagnostic tool.
It's not going to be a perfect oscilloscope - but for $15 it's a great way for beginners to get something that functions and is practical for NBTV use.
