 |
|
Hi all,
I'm trying to record audio in from the mic jack. (There is no line-in on the laptop.) Any recording attempted has no sound. I'm currently just playing audio into it from my phone (to ensure there is a sound source at the jack).
Some general debugging info:
| Code: | $ sudo lspci|grep -i audio
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 09)
00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04)
|
The modules:
| Code: | $ sudo lsmod|grep snd
snd_hda_codec_idt 39116 1
snd_hda_codec_generic 38198 2 snd_hda_codec_idt
snd_hda_intel 15667 3
snd_hda_controller 15893 1 snd_hda_intel
snd_hda_codec 71897 4 snd_hda_codec_idt,snd_hda_codec_generic,snd_hda_intel,snd_hda_controller

I believe everything to be unmuted in alsamixer:
| Code: | $ amixer -c1|

And the final result is 0% sound:
| Code: | $ arecord -f dat -d hw:1,0 --vumeter=stereo /dev/null
Recording WAVE '/dev/null' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
+00%|00%+ |
Suggestions? Thanks! |

Interesting. Putting lspci -n through http://kernel-seeds.org/working.html only yields one known driver and nothing for the "Lynx Point-LP HD Audio Controller." However, searching make menuconfig for "lynx" shows:
| Code: |
│ Symbol: GPIO_LYNXPOINT [=n] │
│ Type : boolean │
│ Prompt: Intel Lynxpoint GPIO support │
│ Location: │
│ -> Device Drivers │
│ (1) -> GPIO Support (GPIOLIB [=n]) │
│ Defined at drivers/gpio/Kconfig:303 │
│ Depends on: GPIOLIB [=n] && ACPI [=y] && X86 [=y] │
│ Selects: IRQ_DOMAIN [=n]
|
I see you have snd-hda-intel enabled, and that appears to be doing something, if not everything. Does anything change if you enable the above kernel option?
