Error ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM none
  • rayg
    Hi I'm just got my raspberry B with PiMame v0.7.10 up and working and the only issue I seem to have is whenever I start up or shut down a game using AdvanceMAME, I get the following error message "ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM none " after about 20 seconds it does load the game and seem to play OK. I current have the sound out of the analog audio jack but got the same error with the sound from the hdmi. I down loaded the image twice and put the it on two different SD cards and got the same error using both.
    I read allot of posts about the this error but I didn't see any that end with the word "none".

    Any help would be appreciated

    Thanks,
    Ray

    what happens if you force audio through the 3.5mm jack?

    sudo amixer cset numid=3 1

  • mholgatemmholgatem
    If that doesn't fix it, use this to set it back to auto instead of 3.5mm

    sudo amixer cset numid=3 0

    Just seen this one, I had that problem too, it disappeared after I updated to the latest version of Raspian after I totalled an install messing about - still don't know what caused it in truth.

    I see the same thing on the 7.10 image, have done an apt-update, not done a firmware update though as this is known to break bluetooth....

    I cd to pimame_installer/ then ran ./update.sh, it when through the update process ... still getting the same error, do I need to do a difference know of software update?

    have you tried running a system update/upgrade? If not, try this:
    sudo apt-get update
    Update is used to resynchronize the package index files from their sources.

    Then:
    sudo apt-get upgrade
    Upgrade is used to install the newest versions of all packages currently installed on the system
