Maybe someone has written a tool like that. Part of the problem is that each sound card is different, providing more or fewer interface options. And, if you have more than one card, like I do, things get even more complex. Here's how to enumerate the cards you have: aplay -l Now, for each individual card, where x stands for the card number, you can query available controls like so: amixer -Cx controls You'l find some cards have lots of controls, and others very few. If you're looking only for volume, grep is your friend like so by way of example: amixer -c2 controls |grep -i volume Of course, if you have but one card, you don't need the -c switch. Now, to get the current setting for any control, again where x identifies the card, and y identifies the numeric id you discovered with the grep above, do like so: amixer -cx cget numid=y Lastly, to set the volume: amixer -cx cset numid=y [value] hth Janina Glenn At Home writes: > Hi, > I'm reading the amixer manpage and I'm unclear on how to set the volume output to 100%. > Is there a simple command to make sure that all is unmuted and at 100%? > Thanks > > > Sent From My Tabletop > N0YJV shade tree computer guy > _______________________________________________ > Speakup mailing list > Speakup@linux-speakup.org > http://linux-speakup.org/cgi-bin/mailman/listinfo/speakup -- Janina Sajka Linux Foundation Fellow Executive Chair, Accessibility Workgroup: http://a11y.org The World Wide Web Consortium (W3C), Web Accessibility Initiative (WAI) Chair, Accessible Platform Architectures http://www.w3.org/wai/apa
