card 3: U0xd8c0x0c [USB Device 0xd8c:0x0c], device 0: USB Audio [USB Audio]

23.81db is too quiet. Much much too quiet. My device is U0xd8c0x0c. I need to boost the capture. I've looked at configs everywhere but I can't figure it out. This is my current asoundrc
| Code: |
ctl.!default {
type hw
card Intel
}
pcm.dmixed {
type asym
playback.pcm {
type dmix
ipc_key 5678293
ipc_perm 0660
ipc_gid audio
slave {
channels 6
pcm {
format S16_LE
rate 48000
type hw
card 0
device 0
subdevice 0
}
period_size 1024
buffer_size 8192
}
bindings {
0 0
1 1
2 2
3 3
4 4
5 5
}
}
capture.pcm "hw:0"
}
|
What can I add to it so that U0xd8c0x0c has the option to have a higher microphone capture? |

There not much you can improve on hardware side, so you should try software side, maybe JACK or something based on, can be used to amp up the signal from your mic.
Ii'm no linux sound expert. Do you use oss , alsa or pulseaudio?
Try pressing f4 or space when selecting mic in alsa mixer to enable capture mode and check if you get an additional bar nammed pcm. |

Sorry again for the huge delay.
Yes, there are no options on the hardware side for this thing.
I use alsa, no sound wrapper or daemon.
I have definitely toggled f4/f5 all of that, and raised my captures to 100%. I don't have an additional bar named pcm, just speaker, mic (does nothing), microphone capture (100% - 23 db), and auto gain control (00) http://img189.imageshack.us/img189/4779/screenshotemj.png for reference again.
I was hoping to avoid any jack daemons and the like and continue using straight alsa, if anyone knows a mic boost line for asoundrc let me have it, otherwise I'll just keep talking loud for now. |
