没有安装tlp时，按到https://bbs.deepin.org.cn/post/286364这帖子能成功解决，音箱的电流声，但是安装好tlp电源管理。发现按https://bbs.deepin.org.cn/post/286364帖子的方法就不启作用了。每次进入系统前第一件事就是在终端输入

sudo sh -c "echo 0 > /sys/module/snd_hda_intel/parameters/power_save"

来暂时解决电流声。

今天终于通过修改tlp参数，解决了电流的声音。下面的是方法

到这里/etc/tlp.conf右键以管理员的身份打开

能后就可以用系统中的文本软件打开了

修改音频省电参数
在文件中找到以下参数（默认可能被注释，即前面带 #），按以下方式修改：

# 禁用交流电源（AC）下的音频省电模式
SOUND_POWER_SAVE_ON_AC=0
# 禁用电池（BAT）下的音频省电模式
SOUND_POWER_SAVE_ON_BAT=0

# 禁用音频控制器的省电（避免控制器关闭导致的问题）
SOUND_POWER_SAVE_CONTROLLER=N

修改好后，强制重启tlp服务

sudo systemctl restart tlp

验证配置

再次运行以下命令查看音频省电模式状态：

tlp-stat | grep -i "sound\|audio"

如果配置生效，会显示类似以下内容：

SOUND_POWER_SAVE_ON_AC=0
SOUND_POWER_SAVE_ON_BAT=0
SOUND_POWER_SAVE_CONTROLLER=N

到这里就应该解决了音箱电流的声音，我的是台式机

下面是我的修改好的tlp.conf

# Settings are read in the following order:
#
# 1. Intrinsic defaults
# 2. /etc/tlp.d/*.conf - Drop-in customization snippets
# 3. /etc/tlp.conf     - User configuration (this file)
#
# Notes:
# - In case of identical parameters, the last occurence has precedence
# - This also means, parameters enabled here will override anything else
# - However you may append values to a parameter already defined as intrinsic
#   default or in a previously read file: use PARAMETER+="add values"
# - IMPORTANT: all parameters here are disabled; remove the leading '#' if you
#   like to enable a feature without default or have a value different from the
#   default
# - Default *: intrinsic default that is effective when the parameter is missing
#   or disabled by a leading '#'; use PARAM="" to disable an intrinsic default
# - Default : do nothing or use kernel/hardware defaults
# - IMPORTANT: parameters must always be specified pairwise i.e. for
#   both AC and BAT. Omitting one of the two makes the set value effective for
#   both power sources, since a change only occurs when different values are
#   defined.

# tlp - Parameters for power saving

# （其他默认注释的参数保持不变，此处省略）

# Enable audio power saving for Intel HDA, AC97 devices (timeout in secs).
# A value of 0 disables, >= 1 enables power saving.
# Note: 1 is recommended for Linux desktop environments with PulseAudio,
# systems without PulseAudio may require 10.
# Default: 1

# 解除交流电源（AC）下的音频省电模式
SOUND_POWER_SAVE_ON_AC=0
# 解除电池（BAT）下的音频省电模式
SOUND_POWER_SAVE_ON_BAT=0

# Disable controller too (HDA only): Y/N.
# Note: effective only when SOUND_POWER_SAVE_ON_AC/BAT is activated.
# Default: Y

# 禁用音频控制器的省电功能（避免控制器关闭导致的问题）
SOUND_POWER_SAVE_CONTROLLER=N

# （其他默认注释的参数保持不变，此处省略）
