Chomebook声音恢复

chromebook Pixel的声音驱动非常独特,刷了除chromeOS的系统后都没法使用声卡,所以常见的解决方式是蓝牙耳机或者是USB声卡

chromeOS的系统是基于linux的,所以linux系统上应当是可以使用的.

解决方法如下:

# 开启声音
CARD="$(aplay -l | grep -Eo '^card ([0-9]): bdwrt5677' | sed 's/card //' | sed 's/:.*$//')"

amixer -c $CARD cset name='DAC1 MIXL DAC1 Switch' on
amixer -c $CARD cset name='DAC1 MIXR DAC1 Switch' on

# 开启外放
CARD="$(aplay -l | grep -Eo '^card ([0-9]): bdwrt5677' | sed 's/card //' | sed 's/:.*$//')"

amixer -c $CARD cset name='Headphone Switch' off
amixer -c $CARD cset name='Stereo DAC MIXL DAC1 L Switch' off
amixer -c $CARD cset name='Stereo DAC MIXR DAC1 R Switch' off
amixer -c $CARD cset name='Stereo DAC MIXL DAC1 R Switch' on
amixer -c $CARD cset name='Stereo DAC MIXR DAC1 L Switch' on
amixer -c $CARD cset name='Speaker Switch' on

# 开启耳机
CARD="$(aplay -l | grep -Eo '^card ([0-9]): bdwrt5677' | sed 's/card //' | sed 's/:.*$//')"

amixer -c $CARD cset name='Speaker Switch' off
amixer -c $CARD cset name='Stereo DAC MIXL DAC1 R Switch' off
amixer -c $CARD cset name='Stereo DAC MIXR DAC1 L Switch' off
amixer -c $CARD cset name='Stereo DAC MIXL DAC1 L Switch' on
amixer -c $CARD cset name='Stereo DAC MIXR DAC1 R Switch' on
amixer -c $CARD cset name='OUT1 Playback Switch' on
amixer -c $CARD cset name='OUT2 Playback Switch' on
amixer -c $CARD cset name='Headphone Switch' on

可以将代码保存为sh文件,然后直接执行

sudo sh enable.sh
