/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.

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.
Here are some of my system information:

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
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
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.
snd_pcm_oss 49412 0
snd_mixer_oss 17056 1 snd_pcm_oss

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
(i take it modules.conf is now ignored with Kernel 2.6?).
alias char-major-116* snd
options snd cards_limit=1
alias snd-card-0 snd-via82xx

Quake 3 /dev/dsp error

I've done some digging trying to search out a solution to this problem, but I am coming up empty.
Fresh install of Quake 3 Arena. On startup, the console reports:
------- sound initialization -------

Could not open /dev/dsp
So I have no sound.
The sound device is a C-Media PCI CMI8738-MC6
Kernel = kernel26-2.6.20.4-1
I've got system sounds aplenty, and sounds playing DVDs and such. My user is a member of audio. Let me output more info than is probably useful.

If I remember correctly this is a rather common problem with quake. I used the following commands to resolve the problem:

Not the most elegant solution I think but it worked for me.

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
1 alsa_pcm:playback_2
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2

/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........

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.

/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.

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...

Running 9i Dev Suite from Solaris server ?

HELP!! Trying to start up the 9i Developers Suite so that I can begin creating Forms and Reports. 9i Enterprise Edition is running on a Unix server. I had the 9i Developers Suite also installed on same server into a new folder OraHome/oracle2. I'm using TedExtend, an Xterm window to access files/folders from a Windows 2000 wrkstn and located the two files: OraHome/bin/f90desm and OraHome/bin/rwbuilder. But I can't get either one of these to run, getting error:
fatal: libjvm.so: open failed: No such file or directory
Killed
Am I missing a step that must be performed prior to running these two, or what?

Bill,
I did a search on Metalink and found a LOT of notes on those two error messages. Seems to be something amiss with your environment. Here are some of the articles to check:

Hi Praveen,
It looks to be more permission issue rather than space issue. Ensure the file system where you copied the DVD has full permission.
Check the installation logs for more details on which other file system needs full permission and work accordingly.

Solaris 10: Mounting a extended partition

Hi, I have Solaris 10 installed in a x86 machine.
I have one hard disk with 3 primary partitions (ntfs, ufs, fat32). I have 1 extended partiton that containts 2 partitions (ext3 and fat32).
Can i mount my extended partitions in Solaris?
I mount my first fat32 (hda2 in linux) partition with:
"mount -F pcfs /dev/dsk/c0d0p2 /mnt/ruben"
In wich way can i mount my second fat32 partition?
"mount -F pcfs /dev/dsk/c0d?s?p? /mnt/david"
Can i mount my linux partition?
Finally, in wich way can i mount my Solaris partition in linux?
I try "mount -t ufs /dev/hda3 /mnt/solaris/
" but it doesn't work.
Saludos.
PD: Sorry for my sucks english :)

Solaris 10 won't reconize your extended partitions, its limited in primary partitions only at this time. This may change ofcourse, it wouldn't surprise me if you see support appear somewhere in either Solaris Express or a later Open Solaris release.
Mounting your linux partition is therefor only possible if its located on an extended partition. As to Linux itself; it heavily depends on the filesystem. I think to have read somewhere that you can add ext2 support in Solaris, but I don't think that'll work for filesystems like reiser, xfs or ext3. (although the latter might be accessible as ext2).
Finally, a little offtopic (but not too much)... Yes, Linux supports mounting Solaris x86 slices, but its very likely that you'll need to recompile your kernel. You'll need to add UFS filesystem support as well as support for the Solaris/x86 partition table.
I suggest checking out a few howto's on www.tldp.org on instructions how to compile your kernel.
