Fedora :: Phonon And ALSA DMix Doesn't Work (F11)?
Sep 2, 2009
I'm using F11, KDE4. I have uninstalled Pulseaudio as it's unusable for my configuration (2 souncards, one of them a M Audio Delta 66). In order to not have Phonon blocking my M Audio Delta 66 card I need to use DMix. The built in ALSA dmix support doesn't show up in Phonon (System Settings -> Multimedia -> Device Preference) but I found out after some research how to add your own dmixer in the ~/.asoundrc file. Here are a few links:
http://noneus.de/?p=50
http://ptaff.ca/ptaffgnu/2009-07/124...dmix_et_phonon
http://amarok.kde.org/wiki/Setting_up_Dmix_for_ALSA
http://alsa.opensrc.org/DmixPlugin#7...e_ICE1712_chip
https://bugzilla.redhat.com/show_bug.cgi?id=474259
[Code]...
It might depend on the way it tries to access this device. When you hover the "DMixer" device it displays it will try the following devices: 1. ALSA: dmixer I think it should rather be ALSA: plug:dmixer But I can't figure out where you are able to configure this, does anyone know? I also wonder how I can remove the Pulseaudio entry in phonon. This is not important but still though PA is uninstalled. There is a Remove button but it's always disabled.

I'm having trouble getting ALSA to play multiple sound streams (multiple sounds at once). My code is running on an embedded ARM board using a AC97 sound. It will only play one without any mixing, I have to use pure ALSA as higher sound mixers are a nightmare to cross compile for ARM. I've tested my system with aplay for example
aplay -D plughw:0,1 bang.wav
works fine. So I tried dmix with
aplay -D plug:dmix Win.wav
That gave the following error
ALSA lib pcm_direct.c:1587snd_pcm_direct_parse_open_conf) The field ipc_gid must be a valid group (create group audio)
aplay: main:550: audio open error: Invalid argument
I checked asound with
/etc # cat asound.conf
pcm.EP93XX {
type hw
[code]....
Does this mean dmix will not work? Is there someway with the above setup I can play multiple sounds? I have to use the vendor ALSA build (so can't update ALSA), I can change the .confs however. Also because I'm cross compiling things like pulseaudio SDL are very difficult to get working, so I basically need to use the above ALSA. Is there anyway I can find if dmix exists on the system?
Should add aplay -L does show dmix ?
iec958 'cards.pcm.iec958'

After update to latest phonon (4.4.0-37) - with kde 4.4.1., it doesn't recognize pulseaudio anymore. I am using xine backend, but I can't find 'PulseAudio Server' device entry in phonon configuration
Is there special pulseaudio configuration so phonon will regonize it? code...

I am experiencing problems with the Gnome ALSA Mixer. I installed Ubuntu on my MacBook Pro inside Windows (I am running Windows via bootcamp), and when I am running Ubuntu the sound doesn't work. After researching the problem online, I was told that one needed to download an application called the "Gnome ALSA Mixer", and switch the mute to off (apparently the mute is default). I downloaded the application, but whenever I try to run it the application window is blank. There are no controls of any sort. I was told when installing Ubuntu inside windows that the disk efficiency (I think thats what is was) is very much reduced, but I don't know if this has anything to do with that.
Also, is there a way to prevent the trackpad from registering stimulus while typing? I find it very obnoxious that every time I try to type in my password or the like that the curser clicks off of where I'm typing, so I am constantly having to move the pointer back and re-click in the area I'm trying to type in (if that makes sense).

I have made a pretty sizable mistake. I was trying to figure out why my game was having sound issues when I was told to update my sound drivers. After a bit of searching, I came across this website. I downloaded and ran the script in the first link. Minor problem: I was using PulseAudio, not ALSA. Needless to say, the script didn't work. After the machine rebooted, I had no sound at all. I was planning on switching to ALSA anyway, so I found this thread and ran the following commands:

Have a couple of very annoying problems. I recently did a re-install of Kubuntu Maverick on my HTPC/fileserver box.It has an onboard (Realtek?) audio card, recognized as... I think, ALC888... Yeah, not sure, KInfoCenter lists a bunch:ALSA Sequencer DeviceUSB 2881 Device ALSA Control Device (my DVB-T stick)ALSA Timer Device
HDA Intel ALSA hardware specific Device
ALC888 Analog ALSA Capture Device
ALC888 Analog ALSA Capture Device

I have been experiencing this peculiar issue with Ubuntu 9.10. Whenever the system boots, the audio doesn't work but when I do a 'sudo alsa force-reload', the volume icon gets muted and on unmuting it the audio works. This is the information regarding the audio device I get on doing lspci
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

I have two sound devices, an internal audio device on my motherboard and an external USB devices, which came with my headset. After upgrading to 11.4, the microphone on my headset ceased to work with my softphone. As it turned out, the softphone used the standard input device, which was defined in the Phonon tab in the KDE System Settings. Unfortunately, when I put the USB Device on top of the default input stack, it doesn't stay there. When I apply the changes and leave the Phonon tab or even enable "Show advanced devices " the stack always resets to its initial order. I was unable to find any kind of config file where Phonon saves this settings.

I am having problems getting sound to work. I have pasted my output from AlsaInfo.sh in hopes that someone can assist me. I have been able to fix this with the AlsaCompile scripts for Ubuntu. I am wondering if this is a distro related issue. If not I will gladly send to the alsa project.

- One sidenote that I will mention is the fact that I DO HEAR SOUND from the following command (and only this command)

I'm using Debian squeezy amd64-based with KDE4.3 from the repo. I've installed kde-minimal package with some additional packages from KDE. Also I have GNOME installed on my system.
So the problem is that when I'm in KDE alsa is not shares between applications. It means that when I'm listening Amarok, for example, I can't play any other sounds in the system, not in browser or KPlayer. And if I stop Amarok playback, I can start listening some other application or watch a movie with a sound.
It looks like I'm using good old OSS again. Back to the 90's =)
In gnome meanwhile all works fine. I suggest that I'm missing some configuration or a package, or something else. I've also tried to install kde-full package, but nothing changed.

i've just created a new .asoundrc which uses dmix. So i can use it in KDEs systemsettings. And all Programs can use the sound devices at the same time. The only Program who makes trouble is skype. If i hear music or watch tv and an skype systemsound comes, i must restart the Soundtrack. Now i have seen that skype uses ALSA. But if i set the default settings, skype would like to have exclusivly access for the sounddevices. Exists any way, to use skype with a mixer like dmix, so all applications have collaborative access to the sound devices.

I should mention that the card actually works and I am able to play sound through all the different out pouts, analog, Adat etc. But what I am not able to do is to use the 8 channels digital adat outputs in 4 separate stereo channels.
If I try configuring my asound.conf with 4 direct pcm devices:
pcm.stereo1 {
type plug
ttable.0.0 1
ttable.1.1 1
slave.pcm "hw:0,0"
}
[Code]....
but when using dmix i am not able to play evan one of the stream, and the I receive an error saying:
ALSA lib pcm_direct.c:978:(snd1_pcm_direct_initialize_slave) unable to install hw params
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:608: audio open error: Device or resource busy

I am facing audio clipping issues when dmix is used for playback. For the test we used a full scale sine wave tone generated using software and encoded as "Signed 16 bit Little Endian, Rate 44100 Hz, Mono". The audio is getting cut out at a 2-3 second interval during playback. This happens only for a fraction of second but it is consistent. This does not happen when audio is played back on the device directly but only when going through dmix. We have observed that there were differences in audio cutting off when the sampling rate was set to 8000Hz and 32000 Hz in asound.conf. The contents of asound.conf is pasted below for your reference:
pcm.dmixer {
type dmix
ipc_key 2048
ipc_key_add_uid true
[code]...
Does this occur due to non-optimal settings of the parameters (buffers, periods) in the configuration or is it some other issue with the ALSA library or the kernel? Please ask if any more setup/configuration settings are required for reference.

I tried to uninstall ALSA and install OSS4. But it seems that ALSA was not the issue. Anyway:
I don't know how to reinstall alsa. I'm using Debian Squeeze(stable).
Tried this code...
cannot open mixer: No such file or directory

I'm having some trouble getting ALSA working on my system. I had been using OSS for awhile but decided to move to ALSA after a kernel upgrade. ALSA worked fine except for the tedious chore of having to run alsaconf everytime I booted up. I was getting errors message for OSS during boot up telling me OSS modules weren't loading properly and linux-headers needed to be installed to get it to work properly again. I ended up installing the linux-headers later due to some nvidia driver fiddling. My system has now reverted back to OSS and I can't seem to get ALSA to work at all. I have libasound2, alsa-base, alsa-utils and alsa-oss installed and alsaconf says no ALSA modules are loaded. I've been searching around and haven't found how to get rid of OSS to install ALSA properly.
Distro: Debian Lenny
Kernel: 2.6.26-2-686
Sound Card: Creative Labs SB Audigy
OSSv4.1
ALSAv-current packages according to synaptic

Debian 8.3 has no sound. Removing/reinstall pulseaudio/alsa-base had no dice.
There was no "alsa force-reload" command on this Debian system.
Detailed info about this alsa: [URL] ....
The sound system was normal (music can be heard) on this pc if installed ubuntu 15.10, here is detailed info about alsa on ubuntu: [URL] ....
Error occurred in both aplay and speak-test:
Code: Select allaplay -D hw:PCH,0 06.wav
Playing WAVE '06.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: pcm_write:1939: write error: Input/output error
Code: Select allaa@de:~$ speaker-test -D plughw:PCH,0 -c 2

Should(How can) I compile/upgrade alsa to the latest version?

I'm on Ubuntu9.10 with pulseaudio setup, everything works fine so far. But when I try to record my Desktop with xvidcap or recordmydesktop I'm unable to get the sound working.
xvidcap uses only OSS so I tried to setup the emulation by loading the kernel modules and adding the following lines to /etc/modules:
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

trying to get ALSA running on a mainboard with onboard Intel soundchip using the snd-hda-intel driver. aplay detects no devices and amixer says: "Mixer attach default error: No such file or directory". Tried everything from the ALSA troubleshooting manual but no success... why is the card not recognized?Here is the output of a debug script I found. Up to now I just did "configure;make;make install" with alsa-utils, alsa-lib and alsa-driver...

I have a Samsung N130 with a Realtek 8192 wifi card (possibly 8192e, I'm not sure) and I am trying to run Fedora 12 on it. I used to run Ubuntu until trying their latest beta and realizing it's not very good, so I looked for something else. Ubuntu was at least easy to get the wifi working with just a few quick commands that were written out, word for word, in order, on the Ubuntu forums. I tried openSUSE on here and it didn't have wifi working out of the box either but people on their forums refused to give me actual instructions and just kept bumping me from thread to thread with people giving vague advice or else just telling me I was looking in the wrong place. I'm hoping that someone can give me clear and detailed instructions on how to get this wifi card working. Keep in mind that I am coming from Ubuntu and so I'm not super comfortable in CLI, if I need to do some CL stuff I will need clear and detailed instructions on how to do that.

Fedora (2.6.34.6-47.fc13.x86_64) I installed that update, during the installation process it said that it had to remove three packages, one of them was kmod nvidia for the old kernel (Fedora (2.6.33.8-149.fc13.x86_64))After the update finished installing the new kernel, I restarted the system and Nvidia did not load. (I assume because Update manager removed the old nvidia? But I also assumed that a new version would be installed automatically?)I received the following Boot messages:
Code:
Entering non-interactive startup
Starting monitoring for VG vg_user1: 3 logical volume(s) in volume group "vg_user1" monitored
[code]....
I'm confused, if Update Manager removed kmod nvidia, then why does yum say it is installed? And why doesn't the new kernel update work with that version? Or should I install a driver version for that particular kernel? I've read while searching that I need to install a kmod-nvidia for that particual kernel version and that I should login to my previous kernel until that happens, is that the problem I'm having?
Why don't rpmfusion and fedoraproject release the kmod-nvidia and kernel updates at the same time to avoid problems such as this? Does anyone know how long does it usually take for rpmfusion to release the new kmod-nvidia driver for the latest kernel?

I have winbind Active Directory authentication set up on my laptop. AD authentication works like a charm, passwords cache, etc. I can use sudo with no problem. However, I cannot use the root account -no matter what I set the root password to, the system will not take it. I also have a couple of normal system users (not winbind), and no matter what I set their passwords to, I cannot login.

For some reason Ctrl+Alt+Fn doesn't work on my Fedora 13 workstation using the nvidia driver. I specified the following in my xorg.conf but it doesn'tption "DontVTSwitch" "off"It is probably not even an Xorg problem because VT switching doesn't work in runlevel 3 either.

I'm using fedora 15 (since its beta), i have had decent experience with software installs and updates and did like gnome 3 Now, coming to the point I have installed linuxdcpp from the standard fedora15 repo "it just doesn't work!!" I can't download filelists or search while others can , i have tried to find similar problem and used their solutions but all was in vain, for instance a guy had similar problem and had recived advice to change incoming connections to firewall manual from active and give ip adress in external/wan (or something ) but it just didn't work even if no one is able to solve this problem , i would appreciate, if someone tells me what exactly is going wrong (or some definitive idea)...
not brag or compare linuxdcpp "just works" in all ubuntu versions from 10.04 through 11.04.honestly this is really annoying i can't easily share files with friends .... ( i had to use dropbox for this!just because i chose a true free gnu/linux ..
