I am trying to determine the frequency of a signal coming into an imx27 processor running linux os 2.6.22 If i were using a micro i would set up a timer for a set period of time and then count up the rising edges coming in. However I am not sure how to do this with C code in linux.
View 14 RepliesI was just wondering if there was a way to use ALSA without PULSE, PULSE AUDIO is causing my Skype to crash continually.
I entered the following command into terminal- sudo apt-get remove --purge pulse-audio
Now my system has no sound at all, soundcards are detected in aplay -l, but unfortunately when i go to sound properties it just says waiting for sound system to respond.
I have no Pulse Audio libraries anymore...not sure how they got deleted. Sound is working fine though....I wasn't using Pulse to begin with, but don't understand what happened to them....think they got deleted in going to KDE 4.4.1 rel 228 today. Should I have those libraries installed for any reason? If so, what should I install?
PS: If I go to Yast, under multimedia, I know longer see Pulse as an option...only hda_snd_intel or whatever
Basically the driver is not working =S no clues to what happened. sound still works in alsamixer but pulseaudio is broke. i kinda need pulse audio to work with wow.

Whenever I play a mp3 on rythmbox and use the "top" command, the pulse audio is at top at 100%.
Is it trying to break my system just by running a mp3?
Is my system not able to detect two cores? or Whatever?
It's just unbearable.

This is a fresh install of 10.10 (although I had the problem on 10.04 as well). I have installed MythTV on here (via apt-get, its not MythBuntu), and use the system primarily for that. Myth works great, sound in everything, no problems.
However, not much else can play sound. Firefox (.....), totem, mplayer, all nothing. Either just no sound or crash. If I can set them to use Alsa (eg: VLC), then they work.
System is an Asus P5B and on-board sound. I've also got an Nvidia GT210 and would like to use the HDMI out, but can't get anything at all to go through this. Don't know if thats related or not. Sound problems existed before adding the GT210.
One strange thing is, I can go into Preferences -> Sound -> Hardware and click "Test Speakers". Of course nothing plays. However, if I then set the onboard card to "Off", and then back to "Analogue Stereo Duplex", then click "Test Speakers", the left speaker works (right is still silent). But from then on, Pulse apps can play sound, until next reboot. Having FF open on a ..... video or something similar prevents Myth from playing sounds however.
What can I do to get sound working sanely? I don't need optical out, surround or anything. Simple stereo will be fine at this point, via either the onboard or the GT210.
I am using Linux mint Debian Version 64 bit.What may be the fix?? I attached the image.
View 1 Replies View RelatedI would like to redirect pulseaudio sound through ssh to a local client while seeing content through a vnc connection. Something like this:
Client: ssh -L 5901:localhost:5901 user@server.net
Client: vncviewer localhost:5901
Server: Run a web browser with flash content on the server through vnc, but sound is redirected to the client.
A good example is Facebook flash games, most flash games require flash player 10 but my local client only supports up to version 9 because of the architechture.
Why? A number of reasons:
- The local client is not powerful enough to run flash content
- The local client has an architechture that flash does not support, eg ARM, PowerPC, etc.
- Save battery power - use the resources of a server instead of the client.
Environment:
Both the client and server have pulse audio installed and working. The server does not have a physical sound card installed but the client does.
Server: Ubuntu 10.04
Client: Ubuntu 10.10
I have tried these links so far: [URL]
I removed pulse because of an issue with HDMI sound, that issue is completely solved now that I'm only using ALSA but I have two issues:
1. My media keys don't higher/lower/mute volume
2. When I go to system -> preferences -> sound, it just comes up with a "waiting for sound system to respond" (but my sound works fine, everything is smooth without pulse other than these two issues)
I get an error saying:
Code: Select allConnection to Pulse Audio failed.
In this case this is likely because Pulse_Server in the environment/X11 Root Window Properties or default-server in client.conf is misconfigured. This situation can also arise when Pulse Audio crashed and left stale details in the Root X11 window. If this is the case then Pulse Audio should autospawn again, or if this not cofigured you should run start-pulseaudio-x11 manually.
I tried reinstalling pavucontrol and pulse audio, but I still get the error. I tried removing bluetooth as well and that doesn't fix the issue.
My wife is reluctant to move from WinXP so I started my own personal campain to promote fedora at home but my wife complains that I "spend too much time fidling with the thing(PC)" and that "it wasn't the case with WinXP" so I =was looking for ways to impress my wife with fedora's capabilities so I flashed her with compiz and dual screen using our old 52" projection tv as a DVR but rhe problem is that my daughter want to watch her DVDs and my wife want to watch a ..... video.I have a system with two Sound card one embedded on the main board and one on a PCI slot and what I am trying to achive is haveing two applications, like two instances of VLC play their sound on the souncard I select per instance, or one Sound card playing VLC and the other playing a ..... video's sound.
I have looked at pulse audio properties and it detects both of my sound cards just fine and it plays wonderfully on either but that is just it... it will pay on either but not both.I have read that you can configure pulse audio to use your second sound card as sorround or duplicate audio but the idea is dicrete audio from dicrete application. Is there such an use case already supported by pulseaudio?So there might be a solution if I disable Pulse Audio but I rather not but I'm open to either.

Not a biggie since I get both sound and video, but it takes a bit longer to start the file then before. Also Kde tells me that the sound card "pulse audio" is no longer connected although pulse seem to live just fine.
When I hit the Pulse Audio Device Chooser icon and then click on 'Volume Control' the volume control GUI flashes on for long enough for me to realise it has flashed on and then is gone again! If I run the chooser as root from a terminal (sudo padevchooser) I get this response when I hit the error:
Code:
**
** ERROR:(pavucontrol.cc:339):void StreamWidget::setVolume(const pa_cvolume&, bool): assertion failed: (v.channels == channelMap.channels)
Strange thing is, I have spent a lot of time working on my wife's laptop and Pulse Audio was working great (after many brain twisting, hair ripping hours of working on it) and indeed is still working despite the lack of GUI. This is all good except I want to change the output device for ringing in Skype and this is where I need to 'Move Stream ...' and can't get to it.
I've been working at this issue myself for two days and still haven't come up with anything. On the default system config with Pulseaudio, Skype 2.1 has absolutely no sound, worse, if I call, or somebody calls me, the program becomes unresponsive and I end up having to either reboot or log out and in again. The only option Skype gives me in the sound settings for anything is PulseAudio Server (local) which, (obviously) is incorrect.So after a few hours of trying to sort it out with pulse, I found a workaround involving the REPLACEMENT of Pulse with esound following these commands in a terminal:
Quote:
killall pulseaudio
sudo apt-get remove pulseaudio
sudo apt-get install esound
sudo rm /etc/X11/Xsession.d/70pulseaudio
This works to an EXTENT. I have output sound, Skype makes all it's little beeps and blips and what-have-you, I can hear the other person clear as day,and I'm able to select different sound card settings now. But when I talk to someone or call echo123, my voice comes through choppy, garbled and extremely distorted.Words are run together at a super fast pace, and sometimes even quickly repeat.So then I tried yet another supposed workaround, this involving modifying .asoundrc as seen here:
Quote:
#asym fun start here. we define one pcm device called "dmixed"
pcm.dmixed {
ipc_key 1025
type dmix[code]...
After applying this, I not only changed my settings to asymed, but ALL the new settings it gave me. This time my words are run together AND I sound like some kind of deep voiced monster.Now, once and for all, to save me another two days of searching through google and topics with unanswered pleas for help, can somebody tell me what is going on here and how the hell do I fix it? T_T.I'm running Skype 2.1, (latest build) on Xubuntu 10.10 with a C-Media CMI8738 sound card. Sound works on all other applications and the microphone is solid, since I just switched from Windows and it worked before now.
P.S. just to avoid people thinking I'm stupid and asking this, yes I am positive that none of the sound settings are on mute. XD

View 1 Replies View RelatedI'm running Kubuntu 9.10, and I like it (yay!) But I've been having issues with sound. Especially under system load I've been having an error where it says that the device analog 9xxx has failed falling back to digital, then it says almost immediately device digital 9xxx has failed falling back to analog. At this point any programs playing sound seem to retain that ability as long as I don't close them, but any programs I open have no sound. This applies to webpages and flash, as well as internal programs. I have also been having issues with video, no errors, but the video skips and freezes. Flash video occasionally crashes and any flash games that submit data (e.g. high scores) to a remote system crash my browser.
I end up having to pause the video and move it back several frames, then wait as if it had to load from ..... for a while, and it will run again for some time. My hardware is a dell inspiron e1505 on which the only things I have done are to replace a broken monitor and upgrade the ram (that is, after I broke windows too many times and converted to Linux. I don't have more error data for you, I simply haven't had the foresight to stick it into a text file yet. The error is displayed in the Notifications and Jobs button in the system tray, which is not well suited to copying and pasting, and I'm admittedly unsure as to how to find the error. I learned BASH on Sun unix at my local college and I still haven't quite learned all of how to speak ubuntu's terminal.
I want to remove pulse and install alsa instead but I can't seem to be able to do it. I tried to search for all packages with "pulse" in their names and purging them but it didn't work because aptitude wanted to remove all of the packages that used pulse with along with pulse.
View 2 Replies View RelatedI have some microphone problems. I can't record anything. (I'm using openSUSE 11.3)
My sound card was detected almost correctly (at least the chip-set was i think). I have an Asrock motherboard (k7upgrade880, with a Southbridge: VIA 8237 | Audio: CMedia CMI9761 6 channel AC'97.
I ran these commands so far with these results - while i was following the audio troubleshooting guide (SDB:Audio troubleshooting - openSUSE
But i have NO audio playback problems - movies, games, music all play well. And the Microphone guid has a broken link
I tried to change my 50-sound.conf file (i read it on a forum, I'm new to linux troubleshooting) from this:
options snd slots=snd-via82xx to this: options snd slots=snd-via82xx position_fix=1
But that did not work either. I did not get any sound with the last line.
i just upgraded from Skype 2.0.0.72 to 2.1.047. Now my microphone isn't working anymore and i cannot select it in the skype options. From now on i can only select the PulseAudio server ..
So i have read some howtos for PulseAudio. They say i should starte PulseAudio Volume Control. ok.. Now i should go to the tab "Recording". This tab doesnt exist on my pc. I upgraded to the latest version of this volume control. It still doesnt exist.
I am using OpenSuse 11.0 with KDE4.3
Here are some screenshots:

PS: My mic is still working with applications, that dont use pulseaudio.
I hear Pulse Audio is the culprit of all the sound issues. I would like to remove it, and default to straight ALSA or whatever distros like Fedora and Ubuntu use, which has never been problematic for me.
View 9 Replies View RelatedI'm trying to capture audio from a stream, NOT from the mic. This is what I'm doing: Start Audacity, push its record button, play a song. It shows that it is recording but when I play back the results, all background noise, conversation, etc, is in the recording as well as the audio from the song. If the mic is unplugged, I cannot record what I hear coming from the sound card (as in what you hear from the sound card is what you get). I got directions on how to do what I want here ( Looking (maybe) for audio mixer for use with Pulse Audio - Page 2 Posts # 4 and 5) but it's not permanent. I got the instructions in post #11 from that same page to make such a change permanent. I tried using the instructions to make the change permanent (I backed up my default.pa just in case something went wrong) and these are the changes I had made:
Code:
### Load audio drivers statically (it's probably better to not load
### these drivers manually, but instead use module-hal-detect --
### see below -- for doing this automatically)
#load-module module-alsa-sink

I have a TV card connected to my Dish box, and I would like to use it on my computer. The tv card works fine, and the audio is connected to my line in. The audio card receives the audio signal, and I can set the volume and record it without any problem, but I can't get it to redirect to an output in order to hear the sound. I have been battling with this issue since a kernel update back when 11.2 was about to come out. Back then, the alsa mixer had an option called audio loop-back, which did the trick. Since I know I ca record the audio and play it back without any problem, is there an application that can do this automatically and simultaneously?
View 1 Replies View RelatedJust noticed that during calls skype uses ~30-50% cpu, + pulseaudio uses ~20%. I found some old threads on this like [URL] Or [URL]. The former suggests to purge pulse and use alsa/oss instead. The latter suggests changing mic in skype to DeviceXX and tweak the pulse.conf
There's also a launchpad bug on that with status Confirmed->invalid (due to "problem fixed in skype 2.1 beta") but looks like it's not (I am using 2.1 beta)
1. Does any1 has this problem?
2. I can't try 2nd link's approach as my skype has only PulseAudio in the settings, so I can't select Device or anything else!
3. Should I try to remove pulse in favor of ALSA? I'm pretty happy with pulse otherwise that this issue, I use it to record sound out of my sound card and I'm not sure if I can do this with alsa/os.
When using Skype, the sound suddenly stops working, both ways (about 4-5 min into the communication). The message "connection failed: connection terminated" is displayed and when I click OK, Pulse Audio closes and Skype freezes. Actually, and I just realized this, the sound suddenly stops working on Firefox as well. (The Alsa plugin in Pulse Audio 'Playback' just disappears). However this occurs after a long period of use. I've just watched about 30 continuous minutes of live soccer through Espn3, before the audio stopped working. No message was displayed though, and just refreshing the page fixed it.
All this makes me think this is some type of Alsa-Pulse Audio problem. I really don't understand well what they are, although I believe Alsa is a driver and Pulse Audio a sound server? Sorry, I started using Linux very recently. I am using Ubuntu-Studio 10.04 and the rt Kernel (2.6.33-29-realtime). Sometimes I use Pulse Audio in Jack and vice-versa, using pactl load-module module-jack-sink and source respectively, but my problem seems to occur even if I unload the modules before using Skype. I believe all this started happening after I started using the rt kernel and/or the module-jack-sink/source.
the situation was that i had 2 fedora 12 boxen. one played flash videos with sound, and one did not! eventually i found the actual problem, and it was trivially fixed (i don't want to remember the many blind alleys i went into first...).
when i looked at
system ==> sound preferences ==> sound
and selected the 'applications' tab, i got the line:
"no application is currently running or recording audio.",
but the mute check box to the right of the 'output volume' slider at the top of the tab was unticked.
however, when i was running a flash video, i had a line:
"alsa plug-in (npviewer.bin) ..." with another mute check box on the right that was ticked! unticking this new mute check box, enabled firefox to play videos video's with sound!
