一.amixer用於控制設置
amixer的幫助提示信息
[cpp]
Usage: amixer <options> [command]
Available options:
-h,--help this help
-c,--card N select the card
-D,--device N select the device, default 'default'
-d,--debug debug mode
-n,--nocheck do not perform range checking
-v,--version print version of this program
-q,--quiet be quiet
-i,--inactive show also inactive controls
-a,--abstract L select abstraction level (none or basic)
-s,--stdin Read and execute commands from stdin sequentially
Available commands:
scontrols show all mixer simple controls
scontents show contents of all mixer simple controls (default command)
sset sID P set contents for one mixer simple control
sget sID get contents for one mixer simple control
controls show all controls for given card
contents show contents of all controls for given card
cset cID P set control contents for one control
cget cID get control contents for one control

Available commands:
scontrols show all mixer simple controls
scontents show contents of all mixer simple controls (default command)
sset sID P set contents for one mixer simple control
sget sID get contents for one mixer simple control
controls show all controls for given card
contents show contents of all controls for given card
cset cID P set control contents for one control
cget cID get control contents for one control
主要用到的命令參數有
controls:列出控制項
contents:列出控制上下文(也就是控制項和值)
cset cID P:設置控制項值
cget cID:獲取設置項值
使用方法:
1.先amixer controls列出所有控制項

這裡控制參數直接復制amixer controls打印出來的數據就行
類似numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch'
[cpp]
root@dvr:/# amixer cget numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch'
numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch'
; type=BOOLEAN,access=rw------,values=1
: values=off
root@dvr:/# amixer cget numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch'
numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch'
; type=BOOLEAN,access=rw------,values=1
: values=off4.根據控制參數類型設置控制參數使用amixer cset +控制參數+" "+參數
記住要用空格隔開控制參數和參數
[cpp]
root@dvr:/# amixer cset numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch' on
numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch'
; type=BOOLEAN,access=rw------,values=1
: values=on
root@dvr:/# amixer cset numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch' on
numid=94,iface=MIXER,name='Left PGA Mixer Line1R Switch'
; type=BOOLEAN,access=rw------,values=1
: values=on5.參數
values表示數值對於volume之類的是具體的數字,在上下文菜單中有顯示數值的范圍,
對於swith之類的表示開關一般是on或off
