Pcm-config-test
From the ALSA wiki
A little program to browse the parameter space of an alsa pcm device. Grab it here:
http://www.affenbande.org/~tapas/wiki/index.php?pcm-config-test
It is useful to find out which samplerates, transport methods, etc., are supported by a device.
pcm-config-test --help
gives this little verbose help:
tapas@mango:~/tmp/pcm_config_test$ ./pcm_config_test --help -- alsa-lib pcm device config tester v0.0.1 -- usage: pcm_config_test <pcm-device-name> [options] options are: --playback --capture --standard-samplerates --samplerate-range x y --standard-periodsizes --periodsizes-range x y --standard-periodcounts --periodcounts-range x y --formats --accessmethods at least one of --capture and --playback is needed. pcm device name must be the first argument!
