Tinny sound from headphones; Analog speaker output seems fine

Asked by Toi Classified

Hi Ubuntu-Gurus - Long time lurker, first time poster. I have gone over various posts and stickys but am not able to figure out how to fix my 'tinny' noise problem from my sound card when connected to headphones. Specifically, when listening via headphones, any vocals (person singing) are completely muffled or very low to the point that when I play a song with vocals, I only hear the instruments. Details on my laptop and chipsets in link below. Any feedback appreciated!

Thanks

Hi :)

I take it that you have started working through the "SoundTroubleshootingProcedure"
https://help.ubuntu.com/community/SoundTroubleshootingProcedure
If not then please start there and see how far you can get!

Hopefully Mark might be along soon to help.
Good luck and regards from
Tom :)

Try:

sudo -i; echo "options snd-hda-intel model=laptop" >> /etc/modprobe.d/alsa-base.conf; exit

Reboot to test. If it is no good / no better, run:

gksudo gedit /etc/modprobe.d/alsa-base.conf

and change the word 'laptop' in the last line to be 'auto'

reboot to retest.

Thanks for the replies!

Tom - I have stepped through the sound troubleshooting guide you reference. My issue is not that I don't have sound. It's that the sound is tinny and garbled with headphones :-(. Thanks for the pointer though.

actionparsnip - I tried both 'laptop' and 'auto' enums in alsa-base.conf and results are the same as before i.e. I still have the tinny noise issue.

Any other recommendation pleae?

Quick Update:

Looks like I had skipped Step-4 in the troubleshooting guide at:
https://help.ubuntu.com/community/SoundTroubleshootingProcedure

So I executed the following commands per the instructions:

cat /proc/asound/{version,cards,devices,hwdep,pcm,seq/clients}; sudo rm /etc/asound.conf; sudo rm -r ~/.pulse ~/.asound* ;sudo rm ~/.pulse-cookie; sudo apt-get update; sudo apt-get install aptitude; sudo aptitude install paman gnome-alsamixer libasound2-plugins padevchooser libsdl1.2debian-pulseaudio; sudo lshw -short;ls -lart /dev/snd; cat /dev/sndstat; lspci -nn; sudo which alsactl; sudo fuser -v /dev/dsp /dev/snd/* ; dpkg -S bin/slmodemd; dmesg | egrep 'EMU|probe|emu|ALSA|alsa|ac97|udi|snd|ound|irmware'; sudo /etc/init.d/sl-modem-daemon status; sudo grep model /etc/modprobe.d/* ; sudo dmidecode|grep roduct; lsmod | egrep 'snd|usb|midi|udio'; aplay -l; sudo lshw -C sound

I think the outcome was that gnome-alsamixer and other utilities were installed. I opened up gnome-alsamixer and played with the headphone slider.

Now the sound is GREAT. I am not 100% sure what did the trick. My settings after I ran the above commands:

I figured out that main problem was with the headphone slider in the 'gnome-alsamixer' app. I played with the slider until I could hear the vocals.

However, I have a new problem. The changes I make in the gnome-alsamixer app is not saved at all. As soon as I close the gnome-alsamixer app, the changes don't reflect when I open the session again.

I tried the fix suggested here: http://ubuntuforums.org/showthread.php?t=1331321
==> But I am not able to find /etc/asound.state

Any simple way to save the gnome-alsamixer app settings? Again my changes are not even being saved in the same session.

Toi Classified.

You might try the following:
1. In a console, enter 'alsamixer' (without the quotes).
This should bring up a gui.
You might play with gui to get used to it.

If the gui showed up, then bring up another console.
2. In this new console, enter amixer sset 'Headphone' 48.
This should set the Headphone level to about 80%.
The alsamixer gui should show this right away.
If the sound is adequate then proceed to 3; if it is still low,
then enter amixer sset 'Headphone' 64.
This should set the Headphone level at maximum.

If the sound is adequate in step 2, then do the following:
3a. In the same console, now type 'sudo su', without the quotes.
3b. Then type 'leafpad gedit /etc/rc.local' without the quotes.
You should see you rc. local file. Save a copy under the
name /etc/rc.local.orig.
3c Then edit rc.local to include the line that worked above,
say, amixer sset 'Headphone' 52.
Put this line just before the original line 'exit 0' in
the original /etc/rc.local.
Save this and then type less /etc/rc.local to see if it
saved ok.
This should reset the alsamixer on every subsequent reboot.

If something goes awry, you can get
back to where you started with the command
cp /etc/rc.local.orig /etc/rc.local.

Hope that helps.

minor edit to the above:

delete 'leafpad' (that's in knoppix)

Thanks for the pointers again.

I added the following into rc.local, and now the headphones work great between reboots.

sleep 10
amixer -c 0 sset 'Headphone' 5 80%, 20%

I believe this is a bug in the alsamixer implementation i.e. changes are not saved across reboots. How do I raise a bug report please?

run:

ubuntu-bug alsamixer

Should get the ball started. Glad you found a goal :)

Toi, Congrats on getting this solved so far! Good work there! It does sound as though a bug-report would be a good idea for the remaining problem. Another way to post a bug-report is this link
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+filebug
although this one might get noticed faster but then progress slower?
https://bugs.launchpad.net/ubuntu/+filebug

Good luck with whichever route you choose. Please let us know the url of the bug-report when you post it or just link it to this thread (see just under your initial question/comment).
Congrats and regards from
Tom :)
