配备第七代英特尔处理器的戴尔 7378 无法发出声音

USB 声卡工作正常，但我无法让英特尔声卡工作。笔记本电脑在认证硬件。

只需将内核升级到 4.8.12 即可

您可以在终端中输入以下内容来执行此操作：

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.12/linux-image-4.8.12-040812-generic_4.8.12-040812.201612020431_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.12/linux-headers-4.8.12-040812-generic_4.8.12-040812.201612020431_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.12/linux-headers-4.8.12-040812_4.8.12-040812.201612020431_all.deb
sudo dpkg -i linux*.deb
sudo reboot
