Using the OSS sequencer mode of ALSA, I noticed that a request for SNDCTL_SEQ_CTRLRATE always returns 100 regardless of the kernel HZ value. I therefore assume that the OSS sequencer mode always works at this rate, unlike real OSS which varies with the kernel HZ, is that correct?

I always works at this rate, unless you have changed it with SNDCTL_TMR_TEMPO or SNDCTL_TMR_TIMEBASE.
