To see which ALSA timers are available, use a command like this: $ cat /proc/asound/timers When a program is using the ALSA MIDI sequencer, you can query the timers assigned to each queue using another command: $ cat /proc/asound/seq/timer Alternatively, the utility "drumstick-sysinfo" [1] shows this information using a friendly format.
