[alsa-devel] [PATCH] speaker-test: Allow sampling rates up to 768000
There are audio devices around that support up to 768kHz playback, allow testing them by increasing the maximum supported sampling rate.

Working with dsd and PCM, I'm scared about the ssd or network storage needed ;). BTW in the past I work even on no-conventional audio device, can we just add some flag to force any frequency or read the max rate supported by audio card?

This is merely a sanity check, and the program accepts only the rate the system supports, in anyway. Note that you can pass a higher rate than the actual card supports; it may be converted by alsa-lib plugin.
