    Re: Sound troubleshooting

    Hi, I've been having sound issues on a new install of Ubuntu 12.04. My sound works for a while and then cuts off

    If, for example, i am watching or listening to something continuously it is fine. However if i open another file, and close the previous one, to watch or listen to something, my sound stops working.

    I am using a digital co-axial cable from built in sound card to my Logitech Z5500 speakers. I can see from the Logitech Z5500 display panel that it is not receiving any sound signal.


    The device i am using is [AD198x Digital]

    aplay -l
    **** List of PLAYBACK Hardware Devices ****
    card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]

    Re: Sound troubleshooting

    I was following the sound trouble shooting guide because of my Nvidia Geforce card

    PHP Code:
    grep "eld_valid *1" /proc/asound/NVidia/eld*
    You should see something like this:
    /
    proc/asound/NVidia/eld#X.0:eld_valid        1 
    When I tried
    sudo grep "eld_valid *1" /proc/asound/NVidia/eld*
    I got nothing.


    When I tried
    sudo grep "eld_valid *" /proc/asound/NVidia/eld*
    I got this
    /proc/asound/NVidia/eld#0.0:eld_valid 0
    /proc/asound/NVidia/eld#0.1:eld_valid 0
    I am unsure where to go from here. Any help would be greatly appreciated.

    Re: Sound troubleshooting

    Thanks U-forum for this posting.
    I followed the links, followed through a couple of the CLIs and now my audio is working again.
    Just marked this post "Still can't hear audio after upgrade" as Solved.

    Thanks,
    IamSamAmI

    Re: Sound troubleshooting

    Hi,
    I am running 12.04 server on a headless system. I realize the server edition doesn't include any sound options/drivers. I've read through the trouble shooting guides and have tried some of their suggestions, but since they are written for a desktop environment, I'm not getting anywhere with them. I would like to keep my headless setup but with sound playback so I can run an MPD server and control it from my mobile telephone.

    When I VNC into a virtual desktop and I look under sound settings there isn't anything listed under the hardware and the setup lists a "Dummy Output."

    For regular use, I use the command line. I've setup VNC for the times my CLI knowledge doesn't match the level of sophistication needed to troubleshoot my issues.

    Thanks for any suggestions.

    The audio device listed under lspci is "nVidia Corporation MCP51 High Definition Audio". I googled it and it seems to be an issue that a bunch of people have, and I followed the guides in the first post but they either didnt work or didnt follow through.

    Thanks in advance!
    hope this helps

    Re: Sound troubleshooting

    Since I upgraded from 12.04 to 12.10, my USB sound device is not working anymore. Headphone sound using the sound device integrated in the chipset is still working correct.
    This are the two devices:
    Code:
    c_w@Thomas-Ubuntu:~$ cat /proc/asound/cards
     0 [Intel ]: HDA-Intel - HDA Intel
                          HDA Intel at 0xeea20000 irq 48
     1 [Speaker ]: USB-Audio - USB Speaker
                          GENERIC USB Speaker at usb-0000:00:1d.7-2.3, full speed
    c_w@Thomas-Ubuntu:~$ lspci | grep -i audio
    00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
    c_w@Thomas-Ubuntu:~$ lsusb

    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

    Bus 002 Device 004: ID 046d:c326 Logitech, Inc.
    Bus 002 Device 005: ID 0c45:1b19 Microdia
    The USB device is the last line in the lsusb output.

    If I use the aplay command to play a sound file, the output looks fine, using both sound devices. The only difference is that I don't hear any sound if I use the USB device

    In the alsamixer, there is only the PCM mixer for the USB device and this is not muted.

    The only further indicator that something is not working with the USB device is that it is marked with a red circle with a line in it in the audio configuration:
    http://dl.dropbox.com/u/16335670/audio.png

    Does anyone know what the symbol infront og the USB device means?

    I tried to use the trouble shooting guide, but the google docs guide is not dealing with USB devices (right?) and the I performed the steps in the other one, but it is not helping...

    edit:
    I also tried both 12.04 and 12.10 live CD and it is NOT working with both. But it was working with 12.04, before I upgraded to 12.10.

    I also tried the USB device with Windows 7 to check if it might be broken, but it's still working there.

    I have no clue what's wrong...

    Re: Sound troubleshooting

    Have a nice brand new ASUS P8Z77-V LE Plus motherboard with built in sound card. I think it's too new for Ubuntu 10.04.4 - I tried 12.04 and 12.10 and the sound card worked fine (all 64-bit).

    But the OS was a piece of garbage and Unity was a nightmare.

    Unfortunately, with 10.04.4 64-bit OS, I only get the sounds of silence...I've gone through the troubleshooting steps but the summary is they all reported 'Sound card not found' - I can post the output if desired.

    Any suggestions or ideas?

    Re: Sound troubleshooting

    Use Lubuntu/Xubuntu 12.10, or switch to Linux Mint's "Cinnamon" desktop. Trying to run an old release isn't the right way to go about finding a replacement for Unity, IMHO.

    Re: Sound troubleshooting

    Thanks - I tried 12.10 and it crashed regularly, so I went with 12.04 LTS - I'm using it as a wrapper for my VMware player anyway, so I just boot into 2D mode and leave it alone.

    I tried the Xubuntu desktop (which I really enjoyed), but it doesn't seem to work well with VMware...C'est la vie!

    Thank you for your help and advice. Problem solved!
