Ubuntu Multimedia :: Sound Crashes When Using Microphone?
May 28, 2010
I use Ubuntu 10.04 but I had this problem in 9.10 too.
I have a problem regarding my sound preferences. I have a microphone and I want to use it to make calls. The problem is that when I speak into the microphone when a program like Skype is used, my sound suddenly crashes(The microphone won't take any input nor will I hear any sound from the speakers if I play a video or music. This gets fixed if I restart the computer). This also happens if I go to Sound preferences → Input or Output and edit something there.
If I don't make any of the above, the sound works just fine as I can listen to music and play videos.
I don't know much about computer hardware but here is some info about my sound card:
Code:
VIA Technologies, Inc. VT1708/A[Azalia HDAC] (VIA High Definifion Audio Controller) (rev 10)
Subsystem: Biostar Microtech Int'l Corp Device 820f

I have had trouble with my sound since installing. I have been able to get output sounds to work by setting my sound output to:Internal Audio Digital Stereo (IEC95 instead of:However, my microphone does not work. I know it was working earlier on but I can't figure out what the settings were at that time.Are there any ideas on what I can try to get the input and output audio working correctly?

I have a zoom H2 and I intend to use its usb microphone function.I connected it and it seems to work with xvidcap if I declare /dev/audio1 as the input device. Well.I want to go further and use it for other purposes and before installing jack and other applications I would like to understand why it does no longer appear in the "Sound preferences" under the 'input" and "hardware" tabs as it was the case the day before.

How can I echo the sound from the microphone to the speakers?
I.e., anything that is picked up by the microphone is played on the speakers immediately, without recording anything. Preferably with the ability to increase the volume.

I recently manage to make my microphone "work". I open the alsamixer and i unmuted the mic. Easy!!! But as i can hear my voice through the speakers i can't record. Actually i compare the alsamixer with the sound preferences. And what I notice is:
i)When i mute the output volume from the sound icon in the alsamixer is also muted.
ii)The same when I increase or decrease the volume.
iii)But in the input tab if I mute increase or decrease the volume nothing happens!
I can only mute unmute and change volume trhough the alsa mixer!
I use an Fujitsu siemens amilo pa 1510 with ubuntu 10.10 which I install from a pendrive.

I've tried to look for a solution for a few days now, and haven't had any results so far. I really hope you can help me so I can get to talk with my girlfriend.I'm running Lubuntu with 10.04 LTS, and alsa version 1.0.23 on Samsung NC10.Hardware works, soundcard is recognized by the OS, modules are loaded, alsamixer volume up and unmuted, sound output is ok, arecord or sound recorder don't get input.
- The microphone hardware works. Having the volumes up I hear the noise from the speakers when tapping the microphone.
- Soundcard is recognized by OS (and like I said, music and all other sound output is perfectly fine)

I should create the bridge between a linear input and output. It is desirable, with possibility to impose effects on a sound. (But it isn't obligatory)
Alsamixer:
lspci | grep Audio:

I have the MCP55 HD Audio on board. Is there a way to configure the mic to mono, 16 bit with 16000Hz sampling as a system input. The signal will be read by the installed program pocketsphinx_continuous.
This is not to make recordings. I can make these settings in KRecord/KDE3. This is for the system input. The mic works with the program and KRecord.
Or must a compatible sound card be installed?

I run ubuntu 10.10 with an 870-g45 motherboard which contains a VIA VT1828S integrated sound chip with 8 audio channels as it states on [URL]... I am having issues with getting microphones to work properly on my computer. Sound output works great but microphones don't. I've noticed when I tested mic's on the sound configuration it would act like it gets input but it would be choppy or laggy sound. Anytime i talk to people on voice chat they say my voice sounds like it keeps clipping in and out and they can't understand a thing I say. I have tried looking on google but any fix I looked at didn't seem to work for me. I don't know if it's motherboard related

i'm having a problem with lmms. unlike some posts in the forum, my lmms does output sound, but after a few minutes it crashes. the program itself will just happily go on, but any sound crashes. i hear a glitch, en thereafter no more sound. the only way to fix it is restarting lmms, which is quite a pain in the *** if you have to do that every 5 minutes . the problem occurs to me every time i use lmms, so it is consistent. it seems to me that it crashes faster when i have a bar that includes somekind of chord; a single tone it can handle, but when there's bi- tri- or multiple tones, it just crashes nearly instantly. i've tried both alsa and pulseaudio, and both have the same problems. and it's not my overall sound that's crashing: rhytmbox and videos will just continue to play sound .

I have some seemingly interrelated issues with music CDs that I can't find threads about. Music CDs don't mount, they just spin for a bit then sit there. While a music CD is in the tray, sound juicer (Audio CD extractor) dies with a Segmentation fault. Rhythmbox dies too with this fault:
Code:
** (rhythmbox:3526): CRITICAL **: atk_object_set_name: assertion `name != NULL' failed
** (rhythmbox:3526): CRITICAL **: atk_object_set_name: assertion `name != NULL' failed
Segmentation fault
This only happens while a music CD is in the tray. All other times, the programs run fine.

I have been trying to play this game dawn-rpg.sourceforge.net and it immediately crashes whenever I try to play sounds. The only other sound in this system I have are the sounds for the bash/dash terminal.
So my questions are:-
a. How do I test if the sound system is working alright.
b. Do I need to increase some kind of priorty/niceness to sound systems to make sure they get the available resources (cpu, memory ) whatever it needs ?
On the same topic, while I was searching on the Net I got this link http://rosegardenmusic.com/wiki/low-latency_kernels .
I know this is actually for people who want to make sounds/music but can some of these ideas/instructions be useful for me as well ?

I can, on rare occasions, login to my gnome desktop with the sound theme enabled, but it usually crashes back to gdm while I'm still looking at the ubuntu logo. It does a resolution change, and I thought that might be my problem.
Then, my son noticed that, on those rare occasions we get into the desktop,the gnome-session crashes whenever a system sound plays.
I disabled the Ubuntu sound theme in failsafe mode, then could login to the normal gnome session.
This isn't the only machine that does this, and the other has the same model of motherboard, the ASRock 4CoreDual-VSTA. code...

flash version 10.0 r45 in firefox plays video, graphics, and sound just fine. however, while i'm playing a video on videos, or listening to pandora, the sound could unexpectedly crash. when this happens, sound doesn't just stop playing. it keeps playing but loops the sound every second or so - it's kind of strange to describe; the sentence, "hello, how are you?" could sound like "he-he-he-he ar-ar you-you-you". has anyone experienced this? i say it happens 'unexpectedly' because i can't replicate the crash on demand, but it happens in every firefox session. it seems that it does not matter what i'm doing - i've tried crashing it by making a flash video full screen and exiting continuously etc. because sometimes it happens when i'm going to full screen or changing tabs.
however, most of the time it happens when i'm not even touching the computer - i'm not sure if some background process can cause flash's buffer to overflow, or whatever. other times, it doesn't even need me to play anything for it to crash the sound in flash - it could loop sound from the first time i tried playing it in flash in that ff session. even when i exit firefox or pause the sound it takes a few second for the loops to stop. however, when i restart firefox the sound is fine until it crashes again and i have to restart, again! i tried removing libflashsupport as i read in other threads that it causes sound issues - no luck there. i uninstalled, installed and all that jazz. tried strace - doesn't report any flash errors for some reason, or as far as i can understand.
i also installed the flash debugger for use with the firebug extension, flashbug addon in firefox, but i'm not getting anything there either - i think it can't locate the flash debugger, although it lists the right version. i haven't had this problem with chromium yet, but i mostly use it when flash sound in firefox crashed and i don't want to reload ff; i think they use the same 'libflashplayer.so'? also, just to clarify, sound from the mplayer plugin works fine, and when the sound crashes in flash it does not cause ff to crash and quit. firefox continues to run normally but when i play sound in flash it starts looping. i've had sound problems in the past and i'm thinking there is something i messed up in the packages i have installed. i uninstalled pulseaudio because it was the only way i could find to get my skype working. how would i know if there are conflicting elements?
here's what i get from 'lsof | grep snd':
code:
firefox 956 angelos mem chr 116,4 3850 /dev/snd/pcmc0d0p
firefox 956 angelos 120r chr 116,2 0t0 3751 /dev/snd/timer
firefox 956 angelos 122u chr 116,4 0t0 3850 /dev/snd/pcmc0d0p
firefox 956 angelos 123u chr 116,8 0t0 3874 /dev/snd/controlc0
keytouchd 4518 angelos 4u chr 116,8 0t0 3874 /dev/snd/controlc0
knotify4 4683 angelos 12u chr 116,8 0t0 3874 /dev/snd/controlc0
kmix 4690 angelos 10u chr 116,8 0t0 3874 /dev/snd/controlc0
keytouchd 8563 angelos 4u chr 116,8 0t0 3874 /dev/snd/controlc0
it seems to me like there should be a conflict between all those using the same sound control? however, why would it just happen unexpectedly? also, is there a way that i could dissociate sound from firefox without having to reload a whole session with many tabs?

I'm trying to use an application (e.g., mplayer) to play sound that comes in my sound card (via the mic jack). (What I'm really trying to do is sync a sports broadcast by putting a delay on AM audio, as described here. I'm stuck at the part where it says "this shouldn't be too difficult".) I've seen some hints that there might be code-heavy solutions using LADSPA or some JACK SDK, but there's just gotta be a simpler way. I'm hoping for something like
Code:
mplayer -delay -7 - < /dev/mic
but I'm darned if I can find it. I'm sure there are plenty of other sports fans who would find this useful for syncing radio with the digital TV feed...

I'd like to know how to get off that noisy static sound from my microphone, because when I use my microphone on programs like skype, the sound static annoy the people who is trying to hear me.I've made some tests using audacity, and I can see that my mic sound is reaaly noisy.On my windows system with the same hardware, this doesnt happen.I'd be glad (and my friends too ) if I could solve this problem.

I have no sound input from my microphone. With a fresh install of 11.4/gnome desktop it was working.
Then all I did was installing the multimedia support from the script in the opensuse guide (which interestingly includes some files for k3b so I suspect there is a conflict of libraries now that some kde libs have been installed) and a full system update. After that, my mic has stopped working.
If it helps at all, the output of the ALSA Information Script at my machine is hosted at: [url]

I used Mumble 1.2.2 for a while on my Slackware 13.1 system without any problems. After some time (before 1.2.3 was released) it suddenly stopped working. A few days ago, I wiped my disk and re-installed Slackware 13.1. Compiling 1.2.3 worked. Running it just stopped with a "FUTEX"-Error. I searched the source code for futex (with "-i" parameter) and didn't found anything. There were matches in the compiled object files. So, it's probably something with Qt.
Then I compiled Mumble 1.2.2 and run it. Worked. But it didn't find my microphone. I can hear everybody else but I cannot talk. I tried every device but there is no sound. If I activate the microphone in alsaconfig I can hear myself, so the microphone seems to work. A few minutes ago, I compiled Mumble 1.2.3. You know what? It runs without any "FUTEX_WAIT" error. But, the microphone does not work.

My headphones jack is broken. I wonder is it possible to force a sound system output sound through microphone jack? As result I want plug-in headphones to microphone jack and get the sound. Or BIOS handle it?

My microphone in skype is crackling on Debian Wheezy stable 7.5 ... It is OK on Windows so it is obviously not the hardware to blame.
I have tried already all the options I could find regarding this on the internet, by changing in /etc/pulse/daemon.conf:
Code: Select all resample-method = speex-float-10
OR
Code: Select all resample-method = speex-float-1
My output was also crackling but I solved it by changing:
in /etc/pulse/daemon.conf:
Code: Select all default-sample-rate = 48000
flat-volumes = no
in /etc/pulse/default.pa:
Code: Select allload-module module-udev-detect tsched=0
I also tried starting skype with
Code: Select all PULSE_LATENCY_MSEC=30 skype
Without any success. Now the output is perfect, but the microphone in skype (haven't tested it elsewhere) is crackling.

I am trying to record using a microphone on a machine running Fedora 14. The microphone itself seems to work fine when plugged into a Windows laptop, and the Linux machine is able to play sound just fine. However, although I can record using the microphone (using arecord or audacity, for example), the recorded audio is super, super quiet. I have run alsamixer, and experimented with every capture source. Anything which had any effect (using arecord -vv to see the dynamic sound level) has been turned up to 100%. Still, recorded audio is barely audible.
I have run:
yum reinstall alsa-utils alsa-plugins-pulseaudio alsa-tools-firmware alsa-firmware alsa-lib
But that made no difference. I ran alsa-info, and the output is here: [URL]. Why my recorded sound is barely audible? My next step is probably going to be to boot to Ubuntu, just to see if it has the same problem.

I have a serious problem with my sound card and Ubuntu 10.04. In the others distros (Gentoo, Sabayon, Fedora, Puppy...) the mic run very good, but in Ubuntu i can't record any sound. I can ear the sound exit from the speaker, but with sw like Sound Recorder, Audacity and Skype i can't record the sound. I tried EVERY setting in alsa mixer/Gnome alsa mixer but I can't resolve the problem.
