No sound on Mint 14 Cinnamon 64 bit

[adambaker]

I just upgraded from Mint 12 to Mint 14, and I find my system without sound. Here's what I've tried so far:

Append "options snd-hda-intel model=generic" to /etc/modprobe.d/alsa-base.conf. Reboot. No joy.
Boot from live Mint 14 disc. No sound.
Boot from live Mint 12 disc. Beautiful melodies.
Install ALSA mixer like this fellow. But the mixer didn't have all the check boxes his showed, so no joy.
Remove Pulse Audio and replace it with ALSA per these instructions. Reboot. Silence remains.

Here are a few relevant lspci lines:

Code: Select all

00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
04:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Barts HDMI Audio [Radeon HD 6800 Series]

Does anyone have suggestions?

Those new 65 bit processors are too advanced for Linux - try again in about a year or so

Alternatively have a look at the output of:

Code: Select all

amixer

If any channel has the word "off" alongside it switch it on again. Example:

Code: Select all

Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum
  Playback channels: Mono
  Limits: Playback 0 - 87
  Mono: Playback 49 [56%] [-28.50dB] [off]

Shows my 'master' channel is [off].

I would switch it on and set the volume with:

Code: Select all

amixer set master 100 unmute

You may have more than one channel muted so you may need to run the command more than once. The 100 figure means the volume is turned up to 100% so if you have a particularly loud speaker system you might want to set a lower level to start with!

I don't think this is the issue. Here's my amixer output:

Code: Select all

Simple mixer control 'Headphone',0
  Capabilities: pvolume pswitch penum
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 3
  Mono:
  Front Left: Playback 2 [67%] [20.00dB] [on]
  Front Right: Playback 2 [67%] [20.00dB] [on]
Simple mixer control 'PCM',0
  Capabilities: pvolume penum
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 255
  Mono:
  Front Left: Playback 132 [52%] [-24.60dB]
  Front Right: Playback 132 [52%] [-24.60dB]
Simple mixer control 'Front',0
  Capabilities: pvolume pswitch penum
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Mono:
  Front Left: Playback 22 [71%] [-13.50dB] [on]
  Front Right: Playback 22 [71%] [-13.50dB] [on]
Simple mixer control 'Capture',0
  Capabilities: cvolume cswitch penum
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 31
  Front Left: Capture 15 [48%] [6.00dB] [off]
  Front Right: Capture 15 [48%] [6.00dB] [off]

"Capture" is my microphone, and I want that one off.

Did you try connecting your headphone or any external speakers to the port? Are you getting audio through that?

[adambaker]

Yes. For every experiment I've listed, I played several audio files listening for audio on my built-in speakers in my laptop and my headphones, with the headphones in both the HDMI and headphone jacks. I even try listening for the system noises both from startup and from adjusting the volume. And all these worked in my Mint 12 installation, and work when I run Mint 12 live from the DVD, and don't work in my Mint 14 install or from my Mint 14 live DVD.

Then I'm not sure, I faced a different issue. In any case try the 3rd solution on this. That solved it for me.

Thank you for the suggestions.

I tried downloading Mint 13 and found the sound worked on the live boot, so I installed that one. I consider this an adequate solution for the time being, though I'd be happy to try other suggestions if I can do them on a live Mint 14 boot.
