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

That's not really elegant.

However, in your case these bits should be set according to the capabilities of the codec.

In the codec driver, I do that. With ASOC, each driver specifies its own capabilities, and ASOC is supposed to reconcile them. My I2S driver is not aware of the codec's capabilities.
