I have a Mac mini early 2007. I installed Ubuntu 14.04 LTS i386 without using the bootcamp and just erasing all partitions(I mean there is no OS X on disk but only Ubuntu.). I have had no problems. Everything is working perfectly but there is no sound. On the tray bar there is sound indicator and seems like sound is working but somehow I couldn't get sound from my speakers. At the System settings when I click Sound-->Test Sound, there is no sound. I searched on Google and found some articles. I tried them out but still no sound.

I tried typing this in a terminal:-

sudo nano /etc/modules

and added these lines to that file:-

snd_aoa_i2sbus

snd_aoa_fabric_layout

snd_aoa_codec_tas

snd_aoa_codec_onyx

but no fix yet. Also I tried alsamixer but it wont open stating:-

No such file or directory

I tried the solutions here but still no fix. Now What can I do to fix my sound ?

Welcome to Ask Ubuntu. Open a terminal with Ctrl+Alt+t and type alsamixer. You will get a terminal based tool for configuring your Sound card . Now try changing the settings there and get back to us. –  Venki Jun 19 at 3:37
    
Hi Venki, thanks for your kindly response when i type alsamixer and enter on terminal system says cannot open mixer: No such file or directory, i also tryed after sudo su and result was the same. –  Sheshman Jun 19 at 20:42
    
Whoa! That is the issue here i suppose. did you try sudo apt-get install alsamixer ?(i.e did you try installing alsamixer?) –  Venki Jun 20 at 1:42
    
yes i did, last night i google it the problem and found some articles about it, i try every step but the result is the same, is there any possibility to do something wrong during installation ? i mean should i try to format and re-install ? –  Sheshman Jun 20 at 4:17
    
"I try every step but the result is the same"- Which article did you exactly try out and what was the result of it exactly?(Add the info reg. this to your question's description) –  Venki Jun 20 at 9:08
