…m aplay manual A '--sleep-min' option was already obsoleted for aplay. On the other hand, a paragraph for the option was left as is. This commit deletes the paragraph. Fixes: 4cb74ae ('Remove sleep_min from aplay') Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>
A '--samples' ('-s') option was added so that record/playback process is
terminated after handling the same number of PCM frames as a value of the
option. However this option is not described in aplay manual.
This commit adds a paragraph for the option.
Fixes: 3d44e2b ('aplay: Add samples argument for playing/recording a given number of samples')

…options
Either '--samples' ('-s') and '--duration' ('-d') option is available
exclusively, according to its semantics and actual implementation.
This commit improves description of manual at this point.

Hi @dbaluta
Thanks for your catching this PR ;) This is our first step to use services on github.com, and things are not decided yet; especially for reviewing/granting process of PR.
In ALSA community, actions over alsa-devel list is ever default communication path. But some developers including me wish actions in github.com side were handled as well. In this point, we need more discussion to find better ways for developers to work for their ideas, and for maintainers to achieve their tasks easily. Anyway, I believe that your 'reviewed-by' tag will be added to commits on my PR, then merged. Thank you. |

Hi,
At present, aplay has two options for duration to process PCM frames.
However, the recent one ('--samples') option is not described yet in
its manual. Furthermore, '-s' option was used for '--sleep-min' option
once and description for this option was left as is. This can puzzle
uses.
This patchset improves description about options for process duration.
