| Post subject: | Audio over HIDM on R5.5 |
Has anyone attempted audio over HDMI on their R5.5 release? If so, did you need to upgrade any packages or make any configuration changes? Thanks in advance for any assistance you can provide. |

Hi Marc, yes I have it working fine on one of my systems and I usually keep a precise log of all mods I make to ensure I can recreate it quickly if something breaks. I had to update alsa to at least 1.0.19. Here are the steps I took (changing to unstable may no longer be necessary as long as you get something of at least 1.0.19): Code: # Update alsa to at least 1.0.19 # Edit /etc/apt/sources.list # change stable to unstable apt-get update apt-get install alsa-source alsa-base alsa-oss cd /usr/src tar xjvf alsa.tar.bz2 cd linux make-kpg modules_image dpkg -i ../alsa*.deb I then had to edit mplayer.conf: Code: # update /etc/mplayer/mplayer.conf # Use HDMI output -- ao=alsa:device=hdmi I then edited /etc/asound.conf as per Alan's how-to and it is simply: Code: pcm.!default {
type plug slave { pcm "hdmi" } } In the setup menus I think I had to specify "hdmi" as my audio output device. For reference, I am using an nvidia chipset on a fairly recent board. C |

Chris, thanks for the reply. A few quick follow up questions: 1. Can you confirm that you are on R5.5, not R6? 2. I am using integrated graphics with Nvidia 7050 graphics. Which nvidia graphics are you using and which driver version? Thanks again for your help! Marc |

Indeed it is R5.5. The commands may have given that away but I'll confirm it. I'm using a P5N7A-VM in this case, I think it has a realtek audio chip but I'm not certain and I can't look at it at the moment. Here is a link to getting it going: http://knoppmyth.net/phpBB2/viewtopic.php?t=19486 I don't recall updating any driver except for the nvidia video driver plus updating alsa per above. The graphics chip is Nvidia 9300. the chipset is nForce 730i. This chip will decode H.264 and VC-1 with VDPAU. C |

I have not tested audio output yet as I am having problems with video over HDMI. Somehow the video output is the wrong color. As an example, where the background is normally blue during a boot, it is showing up as green when connected via HDMI. Also, it is as if the brightness is cranked all the way to maximum. Thoughts? |

Chris, I solved the green-screen problem. When I upgrade alsa I am asked if I want to use the existing content found in "/etc/modprobe.d/alsa-base.conf" or if I want to use the one that comes with the upgraded package. Which choice did you make? Thanks! |

hmmm. I don't recall. I *think* I used the one that comes with the upgraded package. Which would make sense too. You would use the old one if you wanted to preserve options you may have modified. BTW, what was the green screen issue? Given your set up it wasn't obvious to me what the issue would be. |

Christ, I made two changes at the same time, so I can't be certain which resolved the "green screen" problem: 1. Changed from my Dell LCD display to my Samsung Plasma TV. 2. Realized that I was working from a canned EDID, so I re-configured to use the EDID that came back from the Samsung TV. The canned EDID was created while connected to the Dell LCD panel but I don't recall if I was connected via HDMI or VGA when I created the canned EDID. In any event, I am now hitting some other problems: 1. I choose to use the version of "/etc/modprobe.d/alsa-base.conf" that came with the new package. 2. There is no file named "alsa.tar.bz2", but there is a file named "alsa-driver.tar.bz2" so I untared that file. 3. There is no command named "make-kpg", but there is a command named "make-kpkg" on my system. I assumed "kpg" was a typo and when with "make-kpkg". 4. After a bunch of output messages I get the error shown below. Any assistance would be appreciated. Marc Code: make[4]: Leaving directory `/usr/src/modules/alsa-driver'

Hi Marc, I don't have a system that I can try this on at the moment to see if I get the same thing. It is possible that the later alsa packages need a more updated kernel or some other updated dependency. You may wish to go to the specific alsa package that I know works which is: alsa 1.0.19. This is sufficiently old now that you should be able to find a prebuilt package with apt-get so you won't have to compile it. If you get a later version of also with apt then it pull in other dependencies. C |

Christ, apt-get attempted to install 1.0.21, so I suspect you've nailed the problem. How do I get "apt-get" to retrieve 1.0.19? Thanks! |

I'm more of a CentOS/RHEL jockey and I feel my way through debian. I suggest Code: man apt-get should get you the info. I think it would be something like: Code: apt-get module=version
If I had a debian system at hand I would be more specific. But I'm on the road. |

Chris, that's the right syntax, but unfortunately, it doesn't work. Looks like there isn't a pre-built version of 1.0.19 in the repository, or I have the wrong label for the version. I tried all of the following: Code: apt-get install alsa-base=1.0.19
apt-get install alsa-bsae=alsa-driver 1.0.19.dfsg-3 apt-get install alsa-bsae=alsa-driver 1.0.19+dfsg-3\ |

OK -- I am getting closer but probably need a bit of help. I pieced together various google hits and have come up with the following sequence: Code: cd /usr/src
mkdir alsa cd alsa wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.19.tar.bz2 wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.19.tar.bz2 wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.19.tar.bz2 tar xjf alsa-driver-1.0.19.tar.bz2 tar xjf alsa-lib-1.0.19.tar.bz2 tar xjf alsa-utils-1.0.19.tar.bz2 apt-get uninstall alsa-source alsa-base alsa-oss apt-get install xmlto cd alsa-driver-1.0.19 ./configure --with-cards=unknown --with-sequencer=yes make make install cd ../alsa-lib-1.0.19 ./configure --with-cards=unknown --with-sequencer=yes make make install cd alsa-utils-1.0.19 ./configure --with-cards=unknown --with-sequencer=yes make make install I ran this on a test system and I have lost sound. When I try to run alsamixer I get the error "alsamixer: function snd_ctl_open failed for default: No such file or directory" Thoughts? |
