![全新安装 debian 系统静音,找不到音频设备](https://linux22.com/image/93730/%E5%85%A8%E6%96%B0%E5%AE%89%E8%A3%85%20debian%20%E7%B3%BB%E7%BB%9F%E9%9D%99%E9%9F%B3%EF%BC%8C%E6%89%BE%E4%B8%8D%E5%88%B0%E9%9F%B3%E9%A2%91%E8%AE%BE%E5%A4%87.png)
该lspci
命令似乎找不到任何音频设备。

并且alsamixer
是100
。
以下是我从 Windows 驱动程序包中获取的音频驱动程序的信息:

答案1
您的音频设备是 Intel SST 音频,要使声音正常工作,您需要安装non-free
固件firmware-intel-sound
从向后移植:
将以下行添加到您的sources.list
# Backports repository
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free
更新和安装firmware-intel-sound
:
apt-get update
apt-get -t jessie-backports install firmware-intel-sound
