Thanks guys
I tried many times and many methods, and now works
I make this file /etc/modprobe.b/alsa-base.conf
Code: Select all
# Set this to the correct number of cards.
options snd cards_limit=2
options snd-hda-intel id=PCH index=0
options snd-hda-intel id=HDMI index=1
snd-hda-intel is the kernel drive audio
id=PCH is the sound card output
id=HDMI is the hdmi sound output
index option change the order
PCH is default device now
Code: Select all
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: CX20751/2 Analog [CX20751/2 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 1: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
Subdevices: 1/1
Subdevice #0: subdevice #0
Now works sound in my laptop (Kmix use the first alsa device to master channel)
