alsacap - an ALSA device capability lister

alsacap serves to list the sampling rates, number of channels and sample formats supported by installed sound cards and their ALSA drivers.  This helps to find out which parameters do not require resampling (something to be avoided) and to troubleshoot ALSA problems.  ALSA parameters are not always independent: for example, the available sampling rates of a sound card may depend on the selected sample format.  alsacap allows to find out about such restrictions by presetting some parameter values.

I wrote alsacap years ago.  A recent e-mail from a user has reminded me that there is still no official tool with the same functionality.  So I have written a manual page and put it in the AUR.  Enjoy!  If you want to learn more about ALSA parameters, devices and configuration, look at this page that I also wrote some years ago but which is still valid.

Please edit your link. It's not very nice forcing people to vote this way.

Thanks and shame on me!  This was unintentional.

I had copied the URL from the browser after voting, and apparently voting is implemented as appending "/vote" to the AUR directory, without a redirect to the original URL.  I had some trouble in the past with double posting as a result of reloading an AUR page but did not realise the scope of the problem.

Created somewhat the same in bash as a supporting script aimed at helping users to configure mpd for bit perfect playback. See https://github.com/ronalde/mpd-configure.
