<ronj> Hi, I just upgraded my Dell XPS 16 to Ubuntu 11.04. Microphone used to work great under 10.04 and 10.10, but here I can't get it to work. Pulseaudio is running and in my sound preferences I tried the various "Hardware Profiles", as well as differents "Connectors", so I am wondering if could be a ALSA issue though I'm not sure at all... Could anybody help me diagnose?
<gnubien> ronj what kind of mic? internal,external,usb,bluetooth,headset?
<ronj> gnubien, it is an internal mic
<gnubien> laptop or netbook?
<ronj> laptop. audio card is a Intel HDA
<gnubien> ronj tried any alsa model options when alsa starts?
<ronj> gnubien, I'm not sure this is what you mean (I'm a beginner regarding ALSA) but I tried adding options snd-hda-intel model=dell-md6 and options snd-hda-intel model=dell-eq in my alsa-base.conf as mentioned here: http://ubuntuforums.org/showthread.php?t=1574035
, without success
<ronj> gnubien, that's all I tried regarding alsa, else I fiddled in ubuntu's Sound Preferences and pavucontrol
<gnubien> ronj how old is your PC? days? weeks? months? years?
<ronj> 1year, used to work fine without any configuration in the two previous ubuntu releases
<gnubien> ronj need more info; run this command and choose 'upload' when you run the script: wget -O alsa-info.sh http://alsa-project.org/alsa-info.sh
&& bash ./alsa-info.sh
<gnubien> ronj paste the url the script prints to this channel
<ronj> gnubien, here it is: http://www.alsa-project.org/db/?f=78...d4227d74ebd9a1
. That's a nice diagnosis script you have here
<gnubien> ronj: script in use last 3 years, really helpful
<gnubien> ronj your sound card's Codec: IDT 92HD73C1X5
<gnubien> ronj: alsa model options depend on installed alsa drivers version and card's codec
<gnubien> ronj: model options for your card: http://sprunge.us/DVee
<gnubien> ronj: if analog mic try this: model=dell-m6-amic
<gnubien> ronj: if digital mic try this: model=dell-m6-dmic
<gnubien> ronj: run alsamixer after you run alsa force-reload and unmute and set volumes on any new controls, test mic
<gnubien> ronj run this command and talk into the mic and watch the volume meter for movement, volume meter is the last line of output in the terminal, report problems: arecord -f cd -vv /dev/null
<ronj> gnubien, thanks, going to try this. I should set it in /etc/modprobe.d/alsa-base.conf , right?
<gnubien> yea, that is the file to edit
<gnubien> ronj: this line in that file: options snd-hda-intel model=dell-m6-amic
<ronj> gnubien, GREAT
<ronj> dell-m6-dmic works
<ronj> I owe you a beer!
<gnubien> nice, have fun
<gnubien> ronj: email me a cold beer
<ronj> gnubien, one question about your diagnosis, how did you find "<gnubien> ronj: model options for your card: http://sprunge.us/DVee"
<gnubien> ok, got a url...
<gnubien> ronj search for the model options for your sound cards codec at http://home.roadrunner.com/~infofile...ns.for.alsa.23
<gnubien> ronj: search for 92HD73
<gnubien> ronj: that file is from alsa drivers source tarball, file name HDA_INTEL-MODELs or the like
<ronj> gnubien, ok
<ronj> gnubien, last thing: do you think I should file a bug to improve the default behavior? If so, where? Linux/ALSA? Ubuntu?
<gnubien> ronj: try ubuntu forums first, if no fix found then...
<gnubien> ronj search for at these sites? http://news.gmane.org/gmane.linux.alsa.devel http://www.mail-archive.com/alsa-use...ourceforge.net
<gnubien> ronj: if no fix found then...
<gnubien> ronj post a email bug report at the alsa-devel forum and include the url that the alsa-info script created as a reference. file the bug under your codec for your card, its listed in the url that the alsa-info script created. http://mailman.alsa-project.org/mail...nfo/alsa-devel
<ronj> gnubien, perfect. thanks again
, have a nice weekend
