Lubuntu 14.04 on iMac G4, sound not working

[gsn313]

Installed Lubuntu 14.04 on my iMac G4, and the speed of this OS is great . However, while playing youtube videos, only the video works. I've tried to get sound with an html5 audio test, but still no sound. I've come to the conclusion that there's no audio functionality with this Lubuntu 14.04 on my iMac. Also, the gnome mplayer wouldn't play my cd's or dvd's. Would love to get this setup to work. Thanks!

The most common answer I see on askubuntu seems to be to install pavucontrol:

sudo apt-get install pavucontrol

In terminal run pavucontrol

1. In Configuration tab for Built-In Audio

Profile : Analog

Make sure HDMI is not selected.

2. Make sure volume is set in all other tabs of pavucontrol

Ok so I did everythng listed, But in the configuration tab of pavucontrol there's a message: "No cards avaiable for configuration." What should I do now? Thanks again btw!

That's interesting.... what's the output of the following command (if you could, please place in code tags)

sudo lshw -c sound

Thread moved to the "Apple Hardware Users" forum for better support.

Super sorry, I don't know how to use code tags. Is that an html thing? Anyway I ran the code in the terminal and the output was: "PCI (sysfs)" What should I do now?

No worries Here's a quick run down on how to use [code] tags

Aha! Thanks! So my output code is...

PCI (sysfs) 

What does this mean? What steps should I take now? Thanks again!

I just got this working on my 1.25Mhz 20" iMac Lamp with 14.04 and KDE. I could see in dmesg that the snd_powermac module was being loaded so I commented that out in /etc/modules and added:

snd-aoa
snd-aoa-soundbus
snd-aoa-i2sbus
snd-aoa-fabric-layout
snd-aoa-codec-tas

rebooted

Then I started alsamixer (it wouldn't start when snd_powermac was loaded and snd-aoa was't) unmuted and turned everything up and I had sound. I don't have speakers for mine so it is just using the internal speaker.

I didn't mess with the blacklist I just confirmed that the snd-aoa stuff wasn't being blacklisted.

See the second answer here:

Awesome! Thanks for the help! So I went to /etc in the file manager and I only see modules-load.d, and inside of there is something called "cups-filters.conf" which has all of this in it:

# Parallel printer driver modules loading for cups
# LOAD_LP_MODULE was 'yes' in /etc/default/cups
lp
ppdev
parport_pc


There isn't a snd_powermac to comment out, so I'm thinking this is the wrong location. Am I right?
