Yes, we just need to read it. JACK used to use TSC for that, and HPET
support was introduced as similar low-cost alternative to deal with
variable clock frequencies (important on mobile things) and unsynced
TSC. Use of syscalls is kind of fallback.

Audio hardware (interrupts) act as a waitable time source.
