九妹通话声音增大教程
原贴转自 远暮本修改安全不会对手机造成伤害，但是出现问题我不负责，经本人测试声音又一定提升
好了废话不多说下面进行修改/usr/share/pulseaudio/alsa-mixer/paths/nokia-dfl61-twl4030-output-earpiece.conf文件
下面红色部分是我自己标出要修改的地方
# DAC2 Analog is used for sink volume.
# Only the left channel from DAC2 will be used, so it would make sense to mute
# the right channel here, but setting per-channel mute isn't currently
# supported in path configuration files. Having both channels open may consume
# some power needlessly (or maybe not, I don't know).
switch = on
volume = merge
volume-limit = 17 # steps 0-18, 0: -24dB 12: 0dB 17: 10dB 18: 12dB #这一步把=号后面的17修改成18
# Tell Pulseaudio that the left channel volume controls also the right channel.
override-map.2 = all,all
# Shut down DAC1.
switch = off
volume = off
# Enable earpiece output from DAC2 left channel only.
switch = off
switch = off
switch = on
switch = off
volume = 2 #这一步把=号后面的2修改成3
volume = 1 #这一步把=号后面的1修改成2
volume = 61 #这一步把=号后面的61修改成100
# Mute headset output (disable all inputs from DAC 1&2 to the PredriveL mixer).
switch = off
switch = off
switch = off
switch = off
volume = off
# Mute IHF output (disable all inputs from DAC 1&2 to the PredriveR mixer).
switch = off
switch = off
switch = off
switch = off
# The PreDriv volume element is shared by the headset and the IHF outputs, and
# it's muted above, so no need to mute it here again.
# Enable the right mic loopback. The right mic uses only the right channel, so
# we need to enable the right loopbackr oute only.
#
# The sidetone volume level is controlled with this element. Normally this
# element is controlled by a separate module that can dynamically adjust the
# sidetone level to stay constant when the sink volume changes, so this setting
# is usually overridden by such a module. We set the mic loopback to maximum
# volume here statically, so that the sidetone can be tested to some extent
# also without any additional modules.
volume = off
volume = zero
# Disable HAC output
switch = off
修改完成
你可以用VI编辑器在手机上进行修改或者下载我修改好的
你可以下载(附件→→）nokia-dfl61-twl4030-output-earpiece.conf(3.22K)放在n9的MyDocs下用命令行执行：devel-su
密码 rootme
回车后在输入
mv空格/home/user/MyDocs/nokia-dfl61-twl4030-output-earpiece.conf空格 /usr/share/pulseaudio/alsa-mixer/paths/重启即可
你也可以用文件管理器把我修改好的文件(附件→→） nokia-dfl61-twl4030-output-earpiece.conf(3.22K)放到/usr/share/pulseaudio/alsa-mixer/paths/目录下重启即可
