Ubuntu / Apple :: Got Stereo Sound On MacBook Pro 8,3
May 19, 2011
I have a MacBook Pro 8,3 w/ Natty installed on it and noticed on the wiki [URL]... it says sound only comes out of the right speaker. I just want to share that I got stereo sound on my machine by adding `options snd-hda-intel model=mbp55' to the end of `/etc/modprobe.d/alsa-base.conf' and rebooting. I didn't see a solution anywhere else. I haven't done extensive testing, I just know that now I have sound coming out both speakers (and headphone speakers) at balanced volume levels.
When I installed I noticed no sound was emanating from my computer and a red light coming out the headphone jack. s there any reason why there wouldn't be any working sound? Everything else seems to be working fine. I installed the additional drivers but the only ones listed were graphics and wireless.
First macbook. I've managed to get everything I really need running except sound. I'm 5-year ubuntu user so if anyone asks for any system info I'll probably be able to manage it. This is the only sound-related entry I could find in lspci. 01:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)
I installed ubuntu 10.10 in my macbook white 7,1 and as always I am impressed with the support of most of the hardware. Almost everything works, but the sound and the brightness control do not. The sound one is the one that I am more concerned about. I tried to solve it using the documentation for MacBook Pro 7,1 Ubuntu 10.10 (Maverick Meerkat) but the solution did not work.
I have no sound on my macbook pro 17", intel core. I have searched and searched and have not found a solution. I have never yet had sound since I installed ubuntu. I am using 11.04 now.So far, I have edited the document /etc/modprobe.d/alsa-base.conf and added this line:options snd-hda-intel model=mbp55, which did nothing.Also ALSAmixer has all the channels turned up all the way except for S/PDIFI don't think it is a hardware problem because when I play an MP3 file in VLC, in the visualization that would normally show the ups and downs of the sound playback, I get a flat line (not sure if that makes sense).
I manged to have it working fine in Ubuntu 9.04 but the sound settings in gnome have changed too much and I can no longer reconfigure the sound system to work as before. For now I can only hear music through the internal speaker(s) while previously with 9.04 I was able to use the built-in audio jack and use my external speakers. What was even better was that I was able to toggle the between the built-in speakers and the external speakers by plugin/unplugin the speakers jack. Today all of this nice features are gone. What's the proper way for configuring sound with pulseaudio? Should I disable pulseaudio?
My sound was working in the past, but since I upgraded to kernel 2.6.31-20, it's no longer working. I am using Ubuntu on a Macbook and followed instructions from the Macbook 6,1 wiki on [URL]... I just installed the lastest alsa-driver using the following commands:
Im having an odd problem with an installation of 10.04 on my Macbook (the white one with firewire, dunno which generation). Sound works fine from built-in speakers, but when i plug in headphones i have no sound at all..
The levels in alsamixer are all fine, so no problem there..
One of the left speaker on my macbook 2,1 has no sound. The channel is not muted in alsamixer. If you go into sound preferences and change the card to a surround 4.0. The both the front and rear right speakers work. Front is higher sound (tweeter) rear is the lower sounds. (mid-sub) however on the left side the left front does nothing. to the naked ear you can tell not as much sound is coming out of the left side. one speaker is not functioning. is there a fix for this?
So, I've got an Acer 5742G, and the silly thing is only built with one internal speaker. Ubuntu thinks it's my left channel, however Windows 7 'gets it' and plays both channels to that speaker.When I plug in external speakers or headphones, everything works fine.
Bought a new yamaha receiver and have it hooked up to my pc via a y connector on headphone out.
problem: computer speakers work fine when connected to the same audio output described above. when connecting the audio out to my stereo receiver, there is no sound.
the receiver indicates that it is not receiving a signal.
Kinda like sleep timers, this technology has been around longer than dirt as a basic option on TVs, radios and other electronics, and yet why is it so hard to find these options in the modern OS? So far on Google I've seen this question asked repeatedly as far as 4 years ago. Haven't come across an answer...How to enable mono sound instead of stereo?
Until recently, when connected my laptop to the stereo via audio out, i had sound coming only from the stereo. I don't know why and when exactly this happened, but now when the stereo is connected, i get sound from the laptop speakers and stereo speakers simultaneously.Is this a bug? I'd like to mute only my laptop speakers but haven't figured out how. I've tried every setting in "sound" or "audio" or whatever it's called in english, but to no avail.Any ideas how to turn off the laptop speakers?
Alright, the lifehacker article about this Acer machine got me interested in revisiting XBMC as a media center. I bought the AR1600-U910H from Newegg and have been struggling for a couple of weeks to get it working correctly. I opted to install a full Ubuntu desktop to utilize the hardware fully with a standalone version of XBMC. I am currently running Lucid with NVIDIA 256.25 (was running 195 series) driver. Switched to 256 because I heard it fixes the no multi-channel output problem. However, sadly I can't get multi-channel out to work. I have the HDMI output going through my Onkyo TX-SR608 receiver for both audio and video. My problem is I can only get stereo sound out while running XBMC (or any application for that matter).
I've upgraded Alsa to 1.0.23. I've installed new Beta 256.25 NVIDIA driver. I've configured Alsa about 28 different times. I'm at my wits end. So, my question is - does anybody having a similar setup with the ION chip (or the Acer Aspire Revo in particular) where they can succesfully get HDMI digital audio pass through to a receiver (or at least digital multi channel out)? The best I've gotten is 2 channel audio, which doesn't do a lot of good on a 5.1 setup. If I would have known getting multichannel audio would be so difficult I would have rethought starting this endeavor. I don't care if I have to do a fresh reinstall of everything - if that means a different version Ubuntu so be it.
I just got a 5.1 Surround sound system and set it up. I found that it was only working as stereo, though (That is, only the two frontal speakers were producing any sound). I made sure everything was not muted in alsamixer and checked that the hardware was set to 5.1 in the Sound Preferences Hardware tab.
I'm using Ubuntu 10.10 64bit and my sound card is an onboard Intel DG41TY, Realtek ALC888VC codec.
I bought this Radeon 4670 [URL] to improve my video. Although the description on ATI-AMD webpage [URL] specifies that this card can output up to 7.1 audio through HDMI, Sound Controls only shows the stereo and off option. ATI Catalyst does not have any controls for audio. Is there a way to get 5.1 audio enabled? Using 10.04.
I am at the end of my tether in trying to get sound setup on my Ubuntu installation. I have tried many different 'fixes' that people have suggested, but none seem to work!
My setup is as follows: > HP Proliant Microserver > Ubuntu 10.10 > Zotac GT210 card > HDMI from GFX card to AV amp > 5GB Ram
What I want to be able to do is:
> Play music from FLAC files I have ripped in either stereo or sudo 5.1 > Play DVD iso files that I have ripped in the audio format found on the original discs (DTS etc)
I have managed to get sound working before, but only in stereo and I couldn't get it working in XBMC (not the sound from the main movie I chose anyway). I have since completely broken the sound after trying various things found on the interweb and cannot get it back.
I've got a Macbook Air and a verified 9.10 liveCD in the external superdrive. I can successfully boot to the CD, but when I choose "try ubuntu without installing", all I get is a blinking cursor in the upper-left of the screen forever. Any idea why it won't start? CD works fine on my Dell, that's why I say it's verified.
Today i went ahead and installed ubuntu on my windows desktop pc. I tryed the live cd and tested it out and everything was fine i then installed it using wubi. I then wanted to install it to my macbook ( bought in june 2009 ) and i booted the live cd and chose try ubuntu without any change to your computer. It booted a black screen with a white _ at the top then the screen went white and did nothing. I tryed it several times and nothing happend. I then said ok il maybe just try install it through wubi on my bootcamp partition and it all went fine until i got to the windows bootloader and chose ubuntu, it camp up finishing linux installation and where its meant to change and show the ubuntu symbol after ( i know because i've installed ubuntu on the pc) the screen went white. Nothing.
I have a first generation Macbook that shipped with Tiger. I don't often use the os x partition anymore, as I installed Windows XP on a 15 gig partition back when bootcamp was still in beta and I normally use that when I'm on my laptop. Since Tiger is rather old and the only reason I would want to upgrade to leopard is to have access to bootcamp again (they disabled access to the bootcamp application in os x, but I can still boot into windows), I have been thinking about wiping out my os x installation and using ubuntu instead. Does anyone have any thoughts on the pros and cons of totally removing os x?
The main reason I hesitate to just jump in and do it is because if I decide to install os x again I won't be able to install bootcamp again, unless I buy leopard. If I wipe out os x and install ubuntu, will I still be able to access windows in the same way? Windows uses bootcamp drivers to run properly, so I have never quite been sure if it is pulling something off of the os x partition or if it is totally standalone.
I have just installed the latest Ubuntu 10.4 LTS on my Macbook Pro and the one thing I cannot get to work no matter how much i try the fixes and suggestions they do not work. I have the volume controls, even the ones on the keyboard work but there is just no audio what so ever.
I get through the install just fine till the end Iv tryed twice. When i get to the "Who Am I" screen i fill out all the info the "Forward" Button doesn't light up, it keeps on installing till "Ready when you are" and then i'm kinda stuck.. I can go back to past screens and edit the info and stuff but thats it can't move on.
Introduction: I wrote a very extensive and quantified tutorial and informational guide aiming to upgrade the latent information from the wiki's on MacBook Pro 5,2. An accidental toe tap ended with me bumping my head and pressing the X button on firefox. What happen had to be 1 out of a billionth of a chance. So this version will be simple and to the point, until I can muster enough patience to detail it all out again. Please correct any errors.
sudo apt-get install pommed - To get backlight keyboard working. sudo apt-get install cheese - To get iSight working. sudo apt-get install lirc - to get remote working (tested in XBMC) sudo apt-get install bluemon - Pairs Mighty Mouse and Wireless Keyboard (optional)
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?
