microphone now working on pavillion dv2000

Gustav Degreef — Fri, 27 Oct 2006 14:17:26 GMT

I'm using suse linux 10.1 on my pavillion dv2000 laptop. I can get the sound card to work fine, but I can't get the microphone to work. I have a dual boot system and the mike works fine in windows XP. I'm using the alsa snd-hda-intel module and I have google and consulted a lot of linux forums for help without success. Any help would be appreciated. Gustav

Run alsamixer as su, boost the mic input levels. There maybe 2 mic slots there, boost both to normal.

Before that remove all sound modules including the alsa snd-hda-intel module. Run alsaconf and configure your sound card there, do this all at the CLI.

Hey Gustav,

I have a question....???

When you installed SuSE Linux, you had to either delete the RECOVERY drive or you had to format your hard drive.....???

My question is that if you had done the same then how did you get the previously installed environment after installing Linux.

M sorry but I do not want to loose the drivers n utilities which r already installed n as I know the recovery dvds will again make a single partition....so rather spending time on that if you can suggest if you had done sumthing.

Thanks Ragu for the really prompt reply. I understand everything in your suggestion except:

"Before that remove all sound modules including the alsa snd-hda-intel module."

I have an inkling since I've been using linux for 6 years, but I'm not clear on what commands to run. Could you be more specific? Thanks. GUstav

Atul, you should not change the topic of a thread by posting a question on a totally nrelated topic. it messes up the ability of others to follow the discussion. Post a new question on the forum, don't keep replying to this one. But to answer your question, there is a third option which preserves the recovery partition. Repartion the hard drive with gparted live CD or use a proprietary software like Partition Magic.

Gustav, use "rmmod " with the -f or -w option. Remove the modules held by the alsa snd module, remove from the top-level. You can see this by doing an lsmod.

Once the module table is clean of these sound modules, re-run alsaconf as su. Do a tail on syslog/messages too, to read.

Thanks ragu. This is the result. Should I remove other modules first before the two I tried? Gustav

I haven't seen your soundchip, but on most of the ones I've dealt with there are a number of mic settings under alsamixer. Here's a script I use to initialize my mixer. Your "numid's" will probably be different,but it will give you an idea what to look for.

You can get a list of what you have and how they are set with this command. Redirect it to a file as it will be long:

amixer contents

Pay particular attention to "Mic Select." Most on-board sound chips have a lot of features that aren't implemented on the motherboard. Multiple mic's are one, and the wrong one may be selected. Also check "Capture Source" if you're trying to record from the mic.

My script:
#############################################
# Mic Boost (+20dB)--numid=15--type=BOOLEAN #
#############################################
A="amixer cset numid=15 1" ; $A > /dev/null
if [ $? != 0 ] ; then echo $A ; fi
# : values=off

#########################################

#########################################
A="amixer cset numid=32 1" ; $A > /dev/null
if [ $? != 0 ] ; then echo $A ; fi
# ; Item #0 'Mic1'

# : values=1

###############################################
