/dev/audio & /dev/dsp gone

today i tried to get my microphone to work, in desperation i completly reinstalled alsa.
mic is now working but /dev/audio and /dev/dsp are gone... ???
edit:
nevermind. it's because i blacklisted snd-pcm-oss

     Sarah;
  Thanks for the response. 
   I assure you I have searched the whole of forums identified with the sound problems encountered.  I would not start a new post if I had not exhausted the material.
   I have encountered :
   REGISTER ^ sound....et cetera
   REGISTER ^snd...et cetera
and as an alternative....
   REGISTER sound...etcetera
   REGISTER snd.... et cetera
   I tried them both!!!
   I have entered the long list of ...  aliases..more than once!!!
   I probably have more entries into various files as suggested by posts that probably need to cleared out.
    The significant thing I found by comparing this upgrade with the previous arch 2.4.21-1 was the missing files from /root/dev.  The number missing is probably 200 and the significant directories missing are /dev /snd and /dev/sound.
    Searching the forum for pertinent information concerning those particular files showed no reference to them.  I do not know how they are created.  I suspect they weren't properly upgraded when I upgraded to 2.4.24-1.
    I am aware of the procedures extant for alsa and its relevant data entries but my post refers to the missing files in /root/dev which by comparison with arch 2.4.21-1 number in the hundreds.
    I hope you understand my question better.

  • /dev/dsp can't be opened - permissions reset (solved?)

    I'm using udev, and have set up alsa sound on my machine.  I kept getting an error when entering KDE that /dev/dsp can't be opened.  I checked the audio group and confirmed that I was added there.
    I check the /dev files and find that /dev/dsp is assigned to the root group.  I changed that to audio.  It didn't work, but I figured I'd reboot to get everything reset (I come from the windows world), and it still didn't work.  I went back to the /dev files to check things out, and /dev/dsp is again assigned to the root group.  What's going on?

    Thanks; I went back and checked the dev files as indicated and now see how that all works, audio group had permissions.
    I was already a part of audio group, but checked it again - and I wasn't any more; not sure of how that happened but I put myself back in it, and now sound works.
    I had already gone into the Control Panel and set it up for ALSA, although that was just a guess so I'm glad to know I guessed right.
    Now for mplayer and xvid........

  • No /dev/dsp, some programs failed to play sound

    I'm using chakra-2010.09 and there is no /dev/dsp after a default installation. Programs using phonon as backend (KDE's login music and the default music player, Bangarang) can play sound without problems. But others like vlc, flashplugin and wine cannot. Vlc just report errors about no /dev/dsp. How can this be fixed?
    Then I tried #modprobe snd_pcm_oss snd_mixer_oss snd_seq_oss, the module created /dev/dsp1. then I maked a soft link to /dev/dsp but vlc said "cannot open device /dev/dsp".
    I also tried using osspd and vlc can play sound now, but flashplugin and wine still have problems.

  • Can't get sound to work - no /dev/dsp !!!

    I could really do with some help here, this is the first time I have tried to get sound working under linux. I am using a Abit VT6X4 board with on-board sound (VT82C686A) AC97 compliant chipset. I am using Kernel 2.6 which uses the config from the 2.6 package but with added SCSI support. I created the audio group as per FAQ but with ^snd as well as ^sound in the devfsd.conf. I installed all of the ALSA packages, I added snd_via82xx and snd-pcm-oss to /rc.conf, I added the following to /etc/modules.conf
    # ALSA portion
            alias char-major-116 snd
            alias snd-card-0 snd-via82xx
            # module options should go here
            # OSS/Free portion
            alias char-major-14 soundcore
            alias sound-slot-0 snd-card-0

    When I login (as user or root) I get the dreaded no dev/dsp error.
    Now if I ls -la in /dev, I see no dsp file/directory, however, if i touch /dev/dsp I get an access denied error (as root).
    If I lsmod I get the following listed, so the modules appear to load ok.

    Still having no luck here. I added snd-mixer-oss snd-seq-oss  to the /etc/rc.conf.  Farphel, you mentioned setting up the /etc/devfsd.conf to link /dev/dsp to the appropriate devfs entry, could you please give me an example of which lines do this.
    I also inserted the following into /etc/modprobe.conf

  • /dev/dsp on Solaris 10

    I'm running Solaris 10 3/05 on a Dell Optiplex GX260. I installed the audio drivers for my hardware and have a /dev/audio device that gives me basic sound. However, when I start up xmms it complains that there's no /dev/dsp device. Sure enough, there's no /dev/dsp device.
    How can I get a /dev/dsp device?
    Thanks.

    On a Dell Optiplex 745 running Solaris 10 11/06 the built-in Intel soundcard wasn't supported by the OS, so I installed the OSS audio drivers from here:
    http://www.4front-tech.com/oss.html
    which enabled the soundcard.
    I installed xmms from the Solaris 10 companion DVD and upon trying to play a file got the message:
    ** WARNING **: oss_open(): Failed to open audio device (/dev/dsp): No such file or directory
    Checking the output of "ossinfo -v" it turns out the legacy device link for the Intel audio output is named /dev/dsp0 so once the:
    xmms --> Preferences --> Audio I/O Plugins --> OSS Driver 1.2.10 --> Configure --> Audio Device
    was changed from "Default (Intel HD Audio play output)" to "Use alternate device: /dev/dsp0"
    everything worked fine.

  • Capture /dev/dsp?

    This is more of a curiosity than a problem, but anyway. I have a Qosmio X300 notebook based on ICH9 chipset with Intel HDA odboard audio. It is a pretty crappy chip and I'd like to capture it's output. (the "what U hear" thingy). I've googled a bit and found few ways how to do that just by picking the correct recording source in alsamixer, but my soundcard doesn't seem to support recording of anything else than microphone input.
    Then I had the idea of dumping "cat /dev/dsp" to a file and extract the raw data out of it. Problem is that whenever I do that I always get a file that looks like "80 00 80 00 80 00 ..." if I open it in hexa editor. I can send a data stream to /dev/dsp, i.e. something like "cat /dev/urandom > /dev/dsp" makes my card producing noise. Am I missing something, or is the unability of capturing /dev/dsp just another manifestation of the fact that my soundcard cannot caputre it's output?
    I run Arch64 and custom 2.6.32 kernel, I use ALSA for sound and I have no sound server like PulseAudio...

    Your way of reading from /dev/dsp does not work.
    Most probably, your card does not support full duplex, i.e. recording it's own playback. I have the same problem with ICH8.
    The only solution to this problem is to use software routing & mixing. Jackd is one option. I used it to do internet radio. You can basically feed your playback into virtual jackd playback device, then internally route it both to the soundcard and virtual recording device.

  • How to make JACK stop blocking /dev/dsp?

    I'm currently using JACK (with -d alsa) for my sound mixing needs. However, some of my applications use OSS exclusively. Is it possible to make JACK unblock /dev/dsp so those apps can use it when JACK is running?
    (Note that I don't need mixing of OSS applications - I just want sound to work for them.)

    oss2jack isn't really what I'm looking for (plus it's a pain in the neck) - I'd just like a way of having OSS apps run without killing JACK, no mixing necessary.
    Is it possible I might be able to get aoss to work with the JACK alsa-plugin? I've tried that, but I get no sound. Maybe I need to add something to my asoundrc?
    pcm.!default {
    type plug
    slave { pcm "jack" }
    pcm.jack {
    type jack
    playback_ports {
    0 alsa_pcm:playback_1

  • X86_64: Skype2.0 - "RtApiOss: OSS playback device (/dev/dsp) is busy."

    I should say that I managed to get Skype to work by installing the 32-bit alsa-oss and passing Skype through it (i.e. "aoss skype").
    What's confusing to me is that, according to ArchWiki, versions 2.0 and up have native ALSA support. This means that alsa-oss should no longer be necessary, right?
    Running plain Skype in a terminal, I always get the error "RtApiOss: OSS playback device (/dev/dsp) is busy."
    dsp_hijacker has no effect in this case, nor does adding
    pcm.dmixout {
    # Just pass this on to the system dmix
    type plug
    slave {
    pcm "dmix"
    to my ~/.asoundrc (as the wiki suggests). The latter does nothing; running Skype by itself with this modification produces the same error, and Skype with aoss32 works without an .asoundrc.
    Is there some obvious solution that I'm missing?

    @themaister: thanks for pointing that out!
    I removed those modules from rc.conf and added my soundcard modules (according to wiki):
    MODULES=(snd-ice1724 snd-intel8x0 snd-pcm-oss)
    I now have "dev/dsp" and "/dev/dsp1", but still no "/dev/sound/dsp" (though I'm not sure if I need this).
    Hmmmm... It works! I don't know what did it. I retried several steps of the wiki. The last steps I tried were adding my cards with indices to /etc/modprobe.d/modprobe.conf and having alsaconf set up /dev/modprobe.d/sound.conf. Outputs are stille the same as in my first thread. Maybe I got mixed up along the way with pulseaudio installation/removal and blacklisting modules...

  • Recorded audio files are gone after power outage during a concert

    Hello together,
    yesterday I used Logic Pro X to record a concert at our school. I had connected my MacBook Air to our mixer via FireWire, and everything went fine until two minutes before the concert's ending, the power went out. My MacBook was still working from battery, however, Logic Pro stopped recording and all recorded files except for one audio file are gone. I have already tried to recover the lost data by using a data recovery app, but it didn't find anything.
    Is there a way to recover the lost recordings? I mean, Logic must have written its audio files to the hard drive somewhere and even when everything crashed, I don't think the files got overwritten with zeros or something else that could have destroyed it...
    Many Regards,
    Leo Bernard

    I have no idea how, but suddenly the floating Quick Audio control is gone (that normally hovers above your track for quickly raising/lowering audio). I've looked all over on how to reenable it.
    I've checked under 'Window', I've checked in settings, I've spent 15 minutes googling it and can't find any solution but I'm assuming it's something simple that's right in front of me.
    I found an image online and took a snapshot of what it is incase I'm getting the name wrong

  • Flash audio controls is gone from the Windows audio mixer.

    Flash audio controls is gone from the Windows audio mixer. The sound is, but I can not control it separately from the browser. Previously, there was a separate flash and a separate browser. When I use FF3. *. Flash Player audio option was, but the new FF versions do not. For me it was very comfortable and loved.
    How can I repay such opportunity? and whether there is still a possibility?

    Thank cor-el, but it did not help. I tried everything ( I installed it all over again, several times , clean cookies I'm using [[BetterPrivacy 1.68|BetterPrivacy 1.68]] add-ons clean cookies ... ), but the problem is not in the Flash Player to crash. It works. But I can not manage alone plugin container volume and alone audio browser.
    I am not a programmer, so I do not know how I can change it yourself.
    Maybe someone already has it done? I would be grateful if you divide.

  • [SOLVED] After '-Syu' CrystalHD dev suddenly gone?

    I installed the Broadcom bcm970015 as I described in https://bbs.archlinux.org/viewtopic.php?id=135034.
    However, a 'pacman -Syu' and a restart later and now although 'modprobe crystalhd' will apparently load the module, no application seem to be able to access it anymore, and the device '/dev/crystalhd' does no longer exist. I went into the 'driver' and the 'linux_lib' dir that I had left from compiling it back then, and just did another 'sudo make install' in each, but that didn't help.
    Any ideas would be appreciated as I'm clueless of what to do next. Googling the 'cant open crystalhd device' messages from VLC and the example program included with the crystalhd driver will only take me to mac/xbmc sites and the stuff there doesn't seem to match my problem or be of any help, as far as I was able to see.

    Well it turns out for some reason I suddenly had an old crystalhd module installed. Don't ask me where it even came from, I have no idea oO.
    I just noticed this because I saw dmesg giving
    Loading crystalhd 0.9.27
    which is bad. After re-installing the driver, I now get
    Loading crystalhd v3.10.0

    again as it should be. And my /dev/crystalhd device is back.
    However, programs STILL cannot use the card again -.- What I get now from dmesg is this:

    Although I copied over the firmware binary file too (well I did that automatically by sudo make install for the driver + lib).
    I'm stumped why this happens now as I'm still using the same firmware and driver I used in the very beginning when everything actually worked (and before pacman -Syu). How can the image signature fail if the files are exactly the same.. Time to google more.

  • "Use Audio Port for" gone in Mountain Lion

    Where has this feature gone? I remember when I bought my Macbook Pro 13", the headphone jack was advertised as both a headphone and line in jack.
    However it is now advertised as just a headphone jack, this is not what I bought.

    Interesting news about my audio issue...
    I finally called Apple Support after googling around for similar issues and I couldn't find anything. I thought that I might have a hardware problem, but it turns out that my Mac works perfectly. One of the advisors I was talking with told me that the audio jack on the newer MacBook Pros (with the dual Line In/Line Out port) cannot simply have a 1/8th stereo audio cable and it reading as "Line In" under the Sound pane in System Preferences. He said that for whatever reason, Apple removed the option to do that.
    He told me that my only option was to use a USB sound card with a Line In port on it, because that will show up under the Input tab in the Sound pane in System Preferences.
    Then he said that this was something that the engineers could work on and told me to fill out a formhttp://www.apple.com/feedback/macbookpro.html and if they get enough of these feedback requests about the Line In issue, they might consider making a fix for it. I asked the advisor if they actually read these requests, and he said that all of the teams have to read these requests.
    So in the meantime I ordered a USB sound card so I can record sound coming into the Mac.
    So it would be cool if everyone could go to MacBook Pro Feedback and request to have the option to select what the Audio Input can be used for, then maybe they will consider making a fix for this issue.
