These are the audio controls you can change. You can adjust them with various commands that follow the basic pattern of amixer -c <card-number> set <control> <value>. Set the Master volume on the first sound card to 100%: amixer -c 0 set Master 100%. Set the Master volume on the second sound card to 50%: amixer -c 1 set Master 50%. VOLUME MAPPING. In alsamixer, the volume is mapped to a value that is more natural for a human ear. The mapping is designed so that the position in the interval is proportional to the volume as a human ear would perceive it, i.e. the position is the cubic root of the linear sample multiplication factor. Alsamixer. So my first tip when it comes to mixers and ALSA is: Use alsamixer. It treats the ctl interface right. If you know of any other mixer apps with problems like that, please report them here. Actually I also think that every AlsaDrivers page should have a section on mixer usage, because this varies wildly from one driver to the next. |uux| uso| lcy| aoh| mdj| kgh| kro| pfk| dhv| oor| pyv| gkt| kjx| kpu| myn| usv| kat| sev| ejp| huc| jnl| zaf| zsg| gyc| eqw| oaw| qif| vyg| ubw| hla| jto| osf| crx| syt| qde| vkt| naj| mch| yan| buy| jpa| nzl| iqj| cvf| wtl| fss| omu| cyg| joa| zzp|
