昨天我为声卡安装了新的驱动程序，但今天声音不起作用。我找到了这个问题的答案并在 中修复了它/etc/default/grub，但现在当我尝试时sudo update-grub出现了这个错误：
/usr/sbin/grub-mkconfig: 7: /etc/default/grub: splash: not found
这是我的 grub 文件：
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
# MANUELL EINGEFUGT
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pci=use_crs“
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="splash quiet"
# Uncomment to enable BadRAM filtering, modify to suit your needs

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter

#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
我添加了这一行：
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pci=use_crs“
我把这一行注释掉了：
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
我正在使用 Ubuntu 16.04 LTS。

请仔细查看
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pci=use_crs“
您将看到应该“是"，也许您从某个地方复制并粘贴了它。请重写该行并使用键盘，不要复制和粘贴。还有以下行：
GRUB_CMDLINE_LINUX="splash quiet"
重复出现在
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=use_crs"
制作该行：
GRUB_CMDLINE_LINUX=""
