Re: [alsa-devel] How do I tell ALSA that my driver supports every possible sample rate?

To indicate that the PCM device supports all sample rates between the minimum and the maximum, set SNDRV_PCM_RATE_CONTINUOUS in addition to the other supported bits.

So I should do this:

SNDRV_PCM_RATES_5512 | SNDRV_PCM_RATE_8000_192000 | SNDRV_PCM_RATE_CONTINUOUS

Yes.

That's not really elegant.

How could this be made more elegant?

It would be possible for ALSA to automatically set the single rate bits that fall into the minimum/maximum range when the CONTINUOUS bit is set, but this wouldn't help in your case because you'd still need to set these bits in case one of the I2S/codec drivers has to remove the CONTINUOUS bit.
