Greetings,

I'm hoping someone can help me with this issue regarding my sound that has absolutely no bass and so is extremely tinny ( i think my e71 has better sound :lol:

After partitioning my drive and installing Linux Mint alongside OSX SL I was faced with no sound at all. From my previous experience with ubuntu i went through the usual alsa config and setting my sound card I managed to get sound working but just like with my past experience with ubuntu it's really really tinny and just has no bass so not all the speakers are working, it was this exact reason i left ubuntu.

Having tried all the usual suspects ie imac24, imac91, mbp3 etc etc I am still unable to get what i would consider normal sound. I have searched all over for some fix and supposedly found afew but to no avail, so far anyway.

I am really hoping someone can help me with this or at-least point me in the right direction so i can have proper sound.

Many many thanks in advance

GL
 
I'm not sure if LM13 uses ALSA but you can go into a terminal and type alsamixer If you have it it will bring up sound card settings for your system. Chack that all the values are in the correct position.
 
Thanks for your reply NyxCharon the output of lspci | grep -i audio is as follows

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

Hm. Okay need a bit more info.
Code: 
cat /proc/asound/version
Code: 
uname -a
Code: 
 cat /etc/modprobe.d/alsabase.conf

Alsa doesn't have the greatest EQ support out there, so you might need to switch over to pulse audio. Try playing music/etc in VLC or some other program that has a built in EQ. See if you can get the bass working correctly in that program.
 
Certainly, the output of cat /proc/asound/version is

Advanced Linux Sound Architecture Driver Version 1.0.24.

The output of uname -a is

Linux green-iMac 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

and the output of cat /etc/modprobe.d/alsabase.conf is

cat: /etc/modprobe.d/alsabase.conf: No such file or directory

I hear what you're saying about the eq but i have tried switching to pulse and playing with the eq and while it ever so slightly improved the sound by giving it a minute fraction of mid there is still no bass at all. I'm sure all the speakers or a built in sub ( if it has one) isn't working as when i tried to turn the bass up it would just muffle and sounded exactly like it was playing through tweeters. It's nothing to do with the speakers themselves as in the osx partition they work perfectly.

Really appreciate your help with this.

What happened to this thread? Was it solved?
I have almost the same problem, but no sound. Unless its so tiny, I cant hear, I do have to fish tanks in the room so I wouldnt be able to hear anything to quiet. I have almost the same exact output when typing these commands in terminal.
 
Hello Micheal,

I ditched mint and installed ubuntu 12.04 but still had the tinny sound.
I have just fixed it literally 15 mins ago and now have bass working on my linux partition.

I am unsure if this will work in mint as some conf settings that gave sound although tinny in mint didnt give any sound in ubuntu but either way you can try it.

So you need to add mb31 into the gedit alsa conf

reboot then open the alsamixer from terminal and scroll right and unmute enable L
that will give you bass, i also have channels in the alsamixer set to 6 and in the normal sound settings window i have the sound set to analogue surround 5.1 output
You can then lower Front in the alsamixer down a little to fine tune it to your taste. Note pcm, surround, center, Lfe and line should be up to max

They really should put mb31 into the alsa documentation.

Hope this helps and if you get stuck or need more clearer instructions let me know

p.s ditch mint and get ubuntu

Peace
