bas*_*bas 14 sound intel hp hda-intel 15.10
在全新的 HP Probook 470 G3 上全新安装后,一切正常,只有声音:-( 尝试重新安装所有 alsa 部件,但仍然没有声音。
如果手册正确,则是 Conexant CX7501
Alsamixer 仅在 0 上显示所有 spdif (3x)。我无法选择任何其他声卡。好像我错过了(英特尔)驱动程序?
alsa-info 似乎没问题……我想念什么?
另见:http : //www.alsa-project.org/db/?f=fd172ad3823bcaec1a8e2b6af031b394b986a466
这可能是问题:

还是没有声音:-(

我找到了解决方案(!),创建一个新文件 /etc/modprobe.d/intel.conf
添加以下选项:
options snd-hda-intel single_cmd=1
options snd-hda-intel probe_mask=1
