Ubuntu14.04 沒聲音 - Linux

一開始是Asus K55V 雙系統win8 + Ubuntu12.04

幾天前重灌成14.04LTS

然後一開始是喇叭有聲音但是插上耳機沒聲音 型號是Realtek ALC270

參考這篇：http://ceeji.net/blog/fix-ubuntu-sound/

安裝最新版本的驅動

但是AlsaProject說
alsa-driver contains the ALSA components that run in kernel space (e.g. all the
modules). It also contains a few user-space components, including the alsasound
startup script and a set of ALSA headers.
This package is now obsolete, as kernel.org is now taking updates to the
modules directly from the ALSA GIT server.
The old drivers (alsa-driver) are still available.

所以我就用apt-get update驅動到v1.0.27.2

alsa-lib v1.1.0 alsa-utils v1.1.0

然後

就找不到聲卡了

# aplay -l
**** PLAYBACK 硬體裝置清單 ****
aplay: device_list:277: control open (1): 不適用的引數

音效卡本來有聲音的時候是 HDA Intel PCH的 可是現在都變成PulseAudio

參考了

把
/etc/modprobe.d/alsa-base.conf
options snd_mia index=0
options snd_hda_intel index=1
也沒用

#cat/proc/asound/cards
1 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7a10000 irq 32

# cat /proc/asound/devices
