    Isn't alsamixer installed by default? I have it on my system.

    Re: 12.04 No Sound

    I think I just encountered this problem today.

    New note book, HP Pavilion DV-6 series with AMD chipset.
    alsamixer shows ATI R6xx HDMI chip.

    initially installed Lucid (was Win7) then upgraded to 12.04. Doing this solved the wireless network not working problem.

    But now the sound is missing.

    Looks like the default sound playback is S/PDIF instead of the notebook's internal speakers.

    What's the proper way to set the second device as default in 12.04?

    There's no applet way to config this..

    Code:
    $ cat /proc/asound/cards
     0 [Generic        ]: HDA-Intel - HD-Audio Generic
                          HD-Audio Generic at 0xf0344000 irq 42
     1 [Generic_1      ]: HDA-Intel - HD-Audio Generic
                          HD-Audio Generic at 0xf0340000 irq 16

    Re: 12.04 No Sound

    Maybe I can throw in some advice, as I've been discussing alsa/pulseaudio for some time now. If you open a bug report and get the attention of an alsa/pulseaudio developer, this is what they will ask you first of all. You can use these same instructions to fix no sound, wrong card detected, wrong sound output mapping, etc.

    1) Make sure you have snd-hda-codec pointing to /lib/modules/<kernel version>3.2.0-6-generic/kernel/sound/pci/hda
    Code:
    $ sudo modinfo snd-hda-codec
    filename:       /lib/modules/3.2.0-6-generic/kernel/sound/pci/hda/snd-hda-codec.ko
    license:        GPL
    description:    HDA codec core
    srcversion:     A5FF2C826EDE73E58A75D47
    depends:        snd-pcm,snd,snd-hwdep
    intree:         Y
    vermagic:       3.2.0-6-generic SMP mod_unload modversions
    2) Make sure your /etc/modprobe.d/alsa-base.conf, /etc/pulse/default.pa, /etc/asound.conf are unmodified. If you have $HOME/.asound* or $HOME/.pulse*, rename them to something else or mode them to a backup folder.

    3) Report if you have kernel parameters added to your grub kernel command line. You can check your kernel command line using the following command:
    Code:
    $ cat /proc/cmdline
    BOOT_IMAGE=/boot/vmlinuz-3.2.0-6-generic root=UUID=e5064d7d-59ef-4cb5-8e26-c9682ca3d034 ro
    4) Read this and get the latest upstream code via dkms, for your Ubuntu release, from here

    5) Install the dkms file with dpgk and reboot. Example:
    Code:
    $ sudo dpkg -i dkms-hda_-_<some_version>~os_release.deb
    $ sudo reboot now
    6) When rebooting, press Del or F2 (or whatever key is the default to enter the BIOS settings in your system) and go into the BIOS. If you have settings for sound (enable/disable OnBoard Chipset features/sound, enable/disable sound channels, etc), activate sound properly.

    7) Boot and run alsamixer. Press F6 to select the sound card, F5 to show all channels, and verify that none of them is too low or muted.

    8) Check that your speakers are connected to the proper jack (in the case of a desktop). If this is a laptop, also check for sound using headphones.

    9) See that you have proper sound devices in the following files:
    $ cat /proc/asound/pcm
    $ cat /proc/asound/devices
    $ cat /proc/asound/cards

    10) Run aplay -L and try to output sound from your hw and plughw devices. Example:
    Code:
    $ aplay -L
    null
        Discard all samples (playback) or generate zero samples (capture)

    plughw:CARD=NVidia,DEV=9
        HDA NVidia, HDMI 0
        Hardware device with all software conversions
    Using the example above, you would test the hw/plughw devices using:
    Code:
    aplay -D hw:SB,0 /usr/share/sounds/alsa/Front_Center.wav
    aplay -D hw:SB,3 /usr/share/sounds/alsa/Front_Center.wav
    aplay -D plughw:SB,0 /usr/share/sounds/alsa/Front_Center.wav
    aplay -D plughw:SB,3 /usr/share/sounds/alsa/Front_Center.wav
    etc
    - If you manage to get sound from proper outputs for each of your device(s), it means you have to read on pulseaudio on how to create a config to use these sources/sinks properly. Go to pulseaudio website.
    - If still you have no sound, you have to check if your chipset module needs some parameter. Search for its name and eventual parameters in here:
    http://www.kernel.org/doc/Documentat...dio-Models.txt
    Example. My card is ALC892:
    Code:
    $ cat /proc/asound/pcm
    00-00: ALC892 Analog : ALC892 Analog : playback 1 : capture 1
    00-02: ALC892 Analog : ALC892 Analog : capture 1
    00-03: ALC892 Digital : ALC892 Digital : playback 1
    01-03: HDMI 0 : HDMI 0 : playback 1
    01-07: HDMI 0 : HDMI 0 : playback 1
    01-08: HDMI 0 : HDMI 0 : playback 1
    01-09: HDMI 0 : HDMI 0 : playback 1
    Looking at the HD-Audio-Models.txt I see that I need no special parameters for ALC892. But if I needed any, I would add it to /etc/modprobe.d/alsa-base.conf, restart and go back to step 7.
    Code:
    sudo nano /etc/modprobe.d/alsa-base.conf
    options snd-hda-intel some-option-here=some-value

    Re: 12.04 No Sound

    Not the exact issue, but I have had some problems with the audio in recent builds of 12.04. My post on this issue is here.

    The audio slider and alsamixer seem borked.

    Re: 12.04 No Sound

    thanks effenberg0x0.

    Im not able disable any sound card. this machine is a notebook. both soundcards are built in. and nothing in bios permits changing anything. there maybe a newer bios.. I'll look, but I'm not counting on it.

    why isnt there a way to specify the desired sound car within the running ubuntu environment?

    like I said this is a notebook. it has the built in analog sound system and a dvi video port, which I suspect has the spdif...

    also, this notebook is used by more than one person.. a non-admin user needs to be able select sound devices.


    $ cat /proc/asound/pcm
    00-03: HDMI 0 : HDMI 0 : playback 1
    01-00: STAC92xx Analog : STAC92xx Analog : playback 1 : capture 1

    Sound worked when this was running lucid.

    thanks

    Re: 12.04 No Sound

    ok, I create a /etc/asound.conf file.. to specify the default sound card. it shows up in alsamixer. still no sound. rebooted. and encountered a crash. opened bug 909224

    more info -
    even though alsamixer shows the analog sound card as default..
    going into gnome settings -> "username" -> system settings -> sound
    then looking at hardware / input / output ... all are stuck on "hdmi"..

    1. it doesnt recognize the second sound card and two.. cant change anything.

    joy.

    I'm having the same issue with different sound cards. Only the HDMI output is showing up in Sound Settings.

    Code:
    $ cat /proc/asound/pcm 
    00-00: AD198x Analog : AD198x Analog : playback 1 : capture 2
    00-01: AD198x Digital : AD198x Digital : playback 1
    01-03: HDMI 0 : HDMI 0 : playback 1
    01-07: HDMI 0 : HDMI 0 : playback 1
    01-08: HDMI 0 : HDMI 0 : playback 1
    01-09: HDMI 0 : HDMI 0 : playback 1
    I've filed a bug report here:

    https://bugs.launchpad.net/ubuntu/+s...io/+bug/902944

    I have this issue on two separate machines.

    The problem is, I don get a song, and for some reason it tells me that I have an HDMI audio and no microphone, but this is not true at all!
    Please help me, I really need sound!
    There seems to be mass confusion over this HDMI audio. I found it out myself by going into the "PulseAudio" settings. Apparently they haven't included HDMI audio selections in the settings menu under the audio icon. All it has is computer speaker selection. Which is stupid and confusing to newbies. Well if you go into your dash home, type in Pulse Audio. Drag the icon down to the unity bar so you don't have to keep looking for it, since you need to change this every time you switch from HDMI to computer speakers. Now once the Pulse Audio window has opened up you should see a tab called configuration. Click on that, now go to the drop down tab and select the input of your liking. That's it hoped it helped.

    Re: 12.04 No Sound

    I also have no sound, but only from the speakers. I do get audio through the headphones. Is there a way to regenerate the alsa-base.conf file? I did much about it with it in attempts to get all four speakers working, which never did quite work out (Beats Audio, dv6).

    Here's everything I can think to post to help diagnose my problem. Hopefully someone can help.

    Code:
    $ cat /proc/asound/cards
