 |
|
I'm not getting any sound on my Intel HD MID audio. Speaker-test runs with no issues, but no sound. I have everything unmuted and I am apart of the group audio. I am using kernel built in driver snd-hda-intel audio driver. Any suggestions?
localhost one # cat /proc/asound/cards
0 [MID ]: HDA-Intel - HDA Intel MID
HDA Intel MID at 0xf0a00000 irq 28
localhost one #
localhost one # aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: MID [HDA Intel MID], device 0: ID 7675 Analog [ID 7675 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: MID [HDA Intel MID], device 3: ID 2804 Digital [ID 2804 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
localhost one # cat /proc/asound/card0/codec* | grep Codec
Codec: IDT ID 7675
Codec: Intel ID 2804
localhost one #

dman sadly having codec showing their ID "should be" a sign the codecs are not known 
here are mines to see the missign "ID" ref
| Code: | Codec: Realtek ALC892
Codec: Nvidia GPU 40 HDMI/DP
|
So, you should try getting a newer kernel to get a newer alsa, and by that, getting newer codecs.
Without the proper codecs built, no money.
You may try to build the generic codec, it might works. Or check alsa website to see codecs and alsa version need for that card. |
