Microphone sound is too low

Microphone sound is too low and I had to shout to be heard. Is that a problem that can be tuned or not? Other OS have boost mic option. I've test with 3 different PCs.

Thanks.

hi rameshtap,

did you try to adjust microphone settings in any audio mixer?

please run 'alsamixer' in console -> press F4 to switch to 'capture' settings and set all to max.
if that wont work then please post output of 'amixer' command to postebin.com and link here (also run this command on other OS where mic is working fine)

I have tried with slax with 3 more motherboard all of them having same problem
but
with windows on the same hardware it works fine.

Have set the input source to the front mic? Front mic seems to be disabled in your screenshots. Where do you have the microphone plugged in?

Also please show your alsa.conf file if you have one ... it should loo something like: options snd-hda-intel model=

@rameshtap

i have few ideas what you could try:

1) create /rootcopy/etc/modprobe.d/snd_hda_intel.conf file with following content:

Code: Select all

options snd_hda_intel model=auto position_fix=3
as per this arch forum thread: link
that issue was quite different but may be worth trying.
2) go to the BIOS and change sound device to AC97 compatibility mode
3) upgrade to latest rc2 of upcoming porteus-1.2 (maybe newer kernel contains a fix for that)
4) compile latest alsa{lib,oss,utils} from slack-current on porteus (slack-13.37):
link

btw: did you try to connect your mic to the front panel and unmute it in alsamixer?

/etc/modprobe.d/snd_hda_intel.conf

Sorry, i wasn't very clear ... this is the .conf file i meant.
Also i assumed OP was using latest rc2. Please confirm that you have tried plugging into front mic input.

Hi,
fanthom

thanks for your ideas

I have tried with number 1 idea microphone sound gets disturb fully.

My bios does not have the option to change sound device to AC97 compatibility mode. (Gigabyte GA-D425TDU)

I have also tried with latest rc2 but i have not find any recoding software. i have installed krec but it does not get started. I have tried with skype there is same problem the sound is to low.

i have not tried with the 4th option because i am a new user to linux

I have also tried with front mic the sound get more disturb.

What does this mean? Do you have sound but it is very noisy?

If so add: position_fix=1

options snd_hda_intel model=auto position_fix=1
