我安装了 Ubuntu 12.02,但我听不到声音,但如果我连接到 HDMI,我就能听到 HDMI 设备中的声音。
这是我的声音设备
~$ cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xc2420000 irq 129
~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
Subdevices: 1/1
Subdevice #0: subdevice #0
请给我建议以使其发挥作用
