14 The Intel IXP46x PTP timer is known in the manual as IEEE1588 Hardware
15 Assist and Time Synchronization Hardware Assist TSYNC provides a PTP
16 timer. It exists in the Intel IXP45x and IXP46x XScale SoCs.

4 Userspace-driven timers

15 stream with timer sources which we don't have ALSA timers exported for
16 (e.g. PTP clocks), and when synchronizing the audio stream going through
17 two virtual sound devices using ``snd-aloop`` (for instance, when
18 we have a network application sending frames to one snd-aloop device,
19 and another sound application listening on the other end of snd-aloop).
