Ubuntu / Apple :: MacBookPro5.3 NVidia Hd Audio No Sound

Feb 28, 2010

System: MacBookPro5,3 with ubuntu 9.10
kernel: Linux ubuntu 2.6.31-19-generic-pae
soundchip: nVidia Corporation MCP79 High Definition Audio (rev b1), in windows it reports: Cirrus Logic CS4206A (AB 75). Cirrus Logic now is part of nvidia.

I've added ppa mactel repository. and tried the procedure described at:
[url]

It still doesn't work. By compiling from alsa from source, it seems worse, the sound preference even couldn't pick up device. Also in current /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz. I could not find the module name for this nvidia or CirrusLogic device.

Ubuntu / Apple :: MacBookPro5,5 Random Loss Of Brightness Control?

Jan 31, 2010

My MacBookPro5,5 (also known as the June 2009 Unibody MBP) is having brightness problems. Usually, with OOTB Ubuntu, I can control the brightness flawlessly with the keyboard keys labeled F1 and F2 with no problems once I install the nvidia_bl driver. Pommed improves the experience, giving me keyboard brightness.

Since installing yesterday, the brightness control randomly stopped working. Xev reports that the brightness up and down keys return a keycode (whereas F7 - F12, the playback and volume keys do not; both sets control their respective stuff natively)... this shouldn't happen. nvidia_bl is loading properly according to dmesg; so this problem is baffling.

The Gnome brightness applet does not work, nor does auto dimming. The applet displays a helpfully-apt red circle-with-slash mark. "echo x | sudo tee -a /sys/class/backlight/nvidia_backlight/brightness" still works to change the brightness manually. I can get the Gnome brightness working by manually changing the brightness, killing gnome-power-daemon, and then restarting it via the terminal in no-daemon mode.

Ubuntu / Apple :: No Audio With IMac ALC889A Sound Card

Sep 14, 2010

I recently got Ubuntu running on my iMac 20" version 9,1. In the beginning Ubuntu recognized my ALC889A sound card yet I couldn't get my audio to work, however it worked with headphones. Then trying to fix this I updated my kernel and rebooted. Now Ubuntu doesn't even recognize my sound card and I don't get audio on my computer.

Ubuntu / Apple :: Updated Kernel For Sound On Imac Now Nvidia Driver Fails

Apr 17, 2010

I just updated to 2.6.33 kernel and I am using an Intel Mac with ubuntu 9.10 running native. I upgraded because the new kernel has sound working for the imac (at least through headphones). Once the kernel was updated to 2.6.33 the proprietary NVIDIA graphics driver which I had activated through systems -> administration -> hardware drivers is now inactive and will not work. systems -> administration -> hardware drivers says to look in /var/log/jockey.log, here is the last part of that file [URL]. PLEASE HELP OUT. I hate using the Mac os on the other partition.

Ubuntu :: Sound: Mic Doesn't Work - Audio Input Level Graphically Shown In Sound Preferences Shows No Fluctuations In Sound

Aug 3, 2010

I was just using the mic and watched it stop working suddenly. I was in the middle of a skype test call when the graphical mixer level died down to zero in the middle of the call. When the test call was played back, the first part sounded fine then the sound got lower until it became inaudible. Since then I can't get any sound from my mic in skype.

Also, the audio input level graphically shown in Sound Preferences shows no fluctuations in sound as it used to before. The input device is enabled. I tried using Sound Recorder to record some sound clips and that worked fine. So the mic is working but Sound Preferences and Skype seem to have the mic level really low. I'm not sure what else to think considering it was working perfectly a few minutes ago. I've tried restarting, but that didn't fix it either.

Ubuntu / Apple :: Sound Stopped Working, IEC958 Light Turns On Instead Of Sound Playing?

Jan 30, 2011

The sound stopped working on my Macbook Pro 1,1. It was working fine before, and I can't think of any changes I made that would make it stop working. I know it's not a hardware problem because the Apple sound plays when I turn on the computer. Everything is unmuted in ALSA Mixer. None of the hardware options in Sound Preferences produce sound. Plugging in headphones or speakers does not solve the problem. I'm using 10.10.One curiosity: Whenever I do something that would normally cause sound to play, the optical audio red light in the headphone jack turns on, but no sound plays.

Ubuntu :: Test Sound - No Application Sound Through Front Audio Socket - 10.04

Jun 22, 2011

Strange one. Just upgraded my mother-in-law's computer from 8.04 to 10.04 via the update manager. All seems to be working beautifully except ...

* When I run gstreamer-properties and do an output test I get a test sound through the headphones plugged into the front audio socket of the machine using the 'Analogue Headphones' setting in Sound Preferences. (This rules out dead headphones.)

* When I try to play audio through any app I get no sound through the headphones, but if I change the setting to 'Analogue Output' in Sound Preferences I get audio loud and clear through the speakers which are plugged into the audio socket at the rear of the machine. how the gstreamer-properties test is getting audio to the front socket I guess I'd be getting somewhere.

Ubuntu Installation :: No Sound - System Does Not Recognize The Existence Of The Sound Card And Insists On Using Alternative Audio Devices

Aug 22, 2010

New Ubuntu installation with a big problem: no sound.

OS: Ubuntu 10.4.1
Hardware: HP Pavilion Elite e9150t (64 bit)
Sound card: Creative Sound Blaster X-Fi Xtreme Audio

Preliminary checks of sound level settings and obvious dumb stuff but there is still no sound. The problem seems to be that the system does not recognize the existence of the sound card and insists on using alternative audio devices.

Ubuntu / Apple :: Macbook Pro 5.5 + 10.10 = No Audio

Mar 15, 2011

I have installed it on my Macbook Pro 5.5 via rEFIt+ and the install works well except for the lack of sound. I've seen this issue posted about on the forums and I've followed the advice posted here as best I can with my limited knowledge. Terminal didn't recognise the aptitude (command not found). I guess that may be due to an older build of Ubuntu being used in the example?

Hardware :: Unable To Get Sound From M-Audio Sound Card?

Nov 21, 2009

I'm setting up a new PC and hope to use the Planet CCRMA packages for some simple home recording projects. The PC has a 64-bit processor, so I've installed the x86_64 version of Fedora 10. I've done the basic steps of adding the Planet CCRMA repositories and installed their real time kernel, so I'm think I'm ready to try and get started. First, I need to get my sound cards set up right. I have an M-Audio Delta 1010LT card, which I'd like to use for working with music and the Intel HDA card built in to the motherboard, which I'd be happy to use for things like system notifications and other incidental sounds. Here is what the system tells me about the cards:

[code].....

The only ones that produce any sounds when I test them are the HDA Analog device and the Delta 1010 device, but the weird thing is that output seems to be coming out of the built-in output jack (on the motherboard) in either case. Does the OS route output from the Delta 1010 through the built-in card to its output jack? Also, I've connected only the first two RCA analog outputs from the Delta 1010 to my desktop speaker system - should I use a different pair of outputs for testing? Playing a CD directly from the CD drive works, but playing music files from Amarok does not. I'll leave it at that for now. I posted the information above to the Planet CCRMA mailing list threee days ago, but I haven't gotten any responses.

Ubuntu / Apple :: Teeny Tiny Text In NVidia

Jan 10, 2011

So I installed Kubuntu 10.10 on my mac mini 3,1. Everything worked smoothly until I ran the updater and installed the nVidia drivers (I was using an install DVD I burned back when I was doing the beta test. Under nVidia, a lot of text like menus and the like is showing up excessively tiny- like half to one third the size its supposed to. I suspect a problem related to my monitor, which is an LCD TV. This happens at all resolutions.

I can scale up the text in workspace appearance, but the amount of space for menus and icons doesn't change one bit and the larger text just gets chopped off. Anyone had this same problem? I'm really hesitant about going out and connecting a VGA monitor- I don't have an adapter on hand and I'd rather not go explaining to the Apple store that I'm having trouble with it on Linux.

Ironic thing is, text displayed as part of a web page in Firefox shows at the correct resolution. Edit: I got to looking in the nVidia controls, and it says my resolution is 49x50 DPI. That should be like 96x96 or so.

Ubuntu / Apple :: Error - Failed To Initialize The NVIDIA Kernel Module

May 1, 2010

I keep getting a warning messaged almost every time I reboot about Ubuntu running in low-graphics mode on a Macbook 5,1. This has been happening since Lucid Beta 1.

Quote:

Failed to initialize the NVIDIA kernel module. Please see the
system's kernel log for additional error messages and
consult the NVIDIA README for details.

[code]....

After I finish loading in low graphics mode I have to run "sudo nvidia-xconfig". Then, the next reboot the graphics card driver is loaded properly. Is anyone else experiencing this problem or have an idea how to correct it? I know it is a long shot, but do you think doing a fresh install of the stable release would work?

Ubuntu / Apple :: Macbook 5,1 - Failed To Initialize The Nvidia Kernel Module?

This problem has bothered me in both my previous install of 10.04 and my current one. Intermittently, booting into ubuntu results in ubuntu running in low-graphics mode, informing me that the Nvidia kernel module has failed to initialize.Running nvidia-xconfig does not help. Removing and then reinstalling the nvidia driver in Hardware drivers does not help. I experience the issue with both the 173 and current drivers.I love ubuntu, but this is making me seriously consider exploring other distros. Perhaps this not a bad thing - after I return from this exploration,

Ubuntu / Apple :: No Sound On New MBP?

Oct 7, 2010

I have installed Ubuntu 10.04 in MBP that I bought a month ago. I found it easier to install it using the bootcamp through OSX. Ubuntu works well. Nearly everything worked out of the box except the brightness keys and the sound/microphone. I am able to adjust the sound level using the keyboard keys (F10 - F12). However there is no sound. Skype also does not detect a microphone. I searched on the web and found the following instructions:

They did not work either.

Ubuntu :: NVIDIA No Audio And Linksys WMP600N

Feb 13, 2011

I tried out ubuntu and I was beyond impressed with this OS. I decided it was time to do a complete migration to ubuntu. I installed Ubuntu 10.10 on my HP laptop and everything went great. It detected all the drivers and my laptop is working in tip top shape. I decided to install ubuntu on a custom PC I recently bought (used for Java development), and that is when I started to run into problems. These are the specs on my custom pc:

[Code].....

I am using Ubuntu 10.10 64-bit edition on the system. First problem I am having is there is no audio on my system. For this card I'm using an HDMI cable to connect it to my screen. I installed the NVIDIA proprietary drivers and there was no audio. I reverted back to drivers I found on the NVIDIA website and still there is no audio. Second problem I am having is attributed to the wifi card I am using (I think). I keep getting this message on boot after post (and on the terminal after I switch off the X server by stopping gdm):

[Code].....

However, after the system boots I can connect to the internet.

Ubuntu Multimedia :: No Hdmi Audio With Nvidia In 10.04?

Trouble is, now I'm getting no sound through the hdmi to the tv. When I try aplay -l I get info for sound card 0 (HDA Intel), but nothing is showing for soundcard 1e So it's not seeing the card, so I can't configure it.

Does anyone have updated instructions for these kernels?

Hardware :: No Audio With Nvidia GTS 450 ?

Dec 27, 2010

I'm trying to get audio over HDMI.

I can't seem to get the Nvidia card to show up as a sound card.

System Info:
Debian "Sid"
kernel: 2.6.32-5-amd64 (2.6.32-29)
alsa: 1.0.23+dfsg-2

Code:

I've tried adding "options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2" to alsa-base.conf, variations of those options don't seem to have any effect, or sometimes break the ATI audio.
