Ubuntu Multimedia :: Sound To Usb Audio Device Cuts Out After A Few Minutes?
Mar 27, 2010
i am using ubuntu studio karmic and i have a digitech vx400 audio effects pedal which serves as an audio in/out midi in/out device via usb. i can sucessfully set it as the system sound device in system>preferences>sound for both input and output. but, when i play audio through it it only works for a few minutes before the sound stops completely. if i leave the system settings set to the internal sound card and configure jack audio connection kit to go to the usb device, i get the same results on the usb sound. a few minutes of playback at the most.i can restart sound with either "pulseaudio --kill && pulseaudio --start" or "alsactl init" in either situation. just requires restarting the programs. same results after restarting. i think this is alsa related as i have both the system sound and jack using the alsa driver, but i don't truly understand the relationship between pulseaudio and alsa.
I recently bought a set of 2.1 speakers, all is fine. I like to listen to my DAB radio through them. When I boot up, (runlevel 3), sound is there via the mic/line-in jack, but as soon as KDE starts, the sound cuts. I can get it back by:~>alsamixerand then F6 and then scroll to mic, switching to ON and slider up to full and then mic boost up to 65% or so.Can I tell something in KDE to default to mic/line-in on?kmix does not give the full picture I see in other's posts, like here:ImageShack® - Online Photo and Video Hostingjust a single slider under each tab, like this:
This happens nearly anytime I watch any relatively lengthy flash video on ..... or other online flash players. I watch the video, and the audio is fine for a few seconds, but then the audio cuts off as the video continues to play. Sometimes, when I move the scrollbar of the screen/pause and replay the movie, it starts back up again for a few seconds then shuts off or plays the audio I just heard.
I just installed Ubuntu 9.04 on my laptop then immediately upgraded to Karmic 9.10. Pulseaudio installed by default. There's no sound although the mute button is not checked and the volume slide control is at medium. lspci gives:
00:14.2 Audio device: ATI Technologies IXP SB4x6 Hi Definition audio controller (rev01)
System >Preferences >Sound >Hardware tab: blank window "choose a device to configure" Output tab: "dummy" output stereo
So, it appears that somehow the audio device controller in my laptop is not recognized or its driver disabled, possibly by pulseaudio. Sound works fine in Windows 7 part of this dual-booted laptop.
This is one of two niggles I've had in migrating to ubuntu, which I must say is (otherwise) absolutely fab.
Problem 1 is an 18 month old "legacy" ATI card, which refuses to be fixed.
Problem 2 (I suspect) is more solvable.
When listening to music, (either from ..... or rhythmbox) after an indeterminate period of time, (it varies substantially from around 5 mins - 1 hour) the sound cuts out without warning. Videos continue to play, but in silence. This silence affects the browser as a whole (chromium). A workaround for this has been to simply restart the program, but this is becoming quite annoying. Sometimes issuing
I've recently upgraded to 10.04, and never had any problems in 9.10, but now, sometimes when Banshee attempts to play a sound file, it will kill my sound output until I reboot. Haven't been able to get anywhere by fiddling with ALSAmixer or the like, and everything is just fine on reboot, but the files don't always cause problems, and they were all fine back in 9.10. Has anyone else encountered this? I've been unable to find any other references to this problem.
When the opening little music plays during start up, the first half of it is loud, but halfway through, the sound cuts to about half volume. Everything else afterwards is also very quiet. After boosting the volume output to 150%, and boosting VLC's audio output to 200%, the audio is still barely audible on my laptop. I've gone into alsamixer, and it's at max. I once found how to reset the audio card, and the sound was normal again, but only until I shut the laptop off, and next time, it was the same as always.
I'm on Ubuntu 9.10, and using an old Toshiba Satellite laptop. Don't know what my sound card is.
I have a Dell Inspirion 5150. The onboard sound card was blown 3 years ago. OS is Ubuntu 8.10. I am also a HAM radio operator and use the computer for digital modes using a USB device that acts as an external sound card modem for me.
The program that I use for that is fldigi. The device is Signalink USB by Tigertronics. the device has the ability to have speakers plugged in to it. Question: Is there a way to have the computer send the audio out the USB cable to the device?
I have looked at my sound settings and there are USB devices but none of them are the one(s) that I use with my Signalink device. If it can't be done, no worries -- have not really needed it so far. Just something nice to have.
I have detected some problems when I try to record sound in my Kubuntu 10.04 system.
The problem is that the "default" device for audio recording does not work but I have to select another device to do so. I always selected the "default" device for audio recoding but currently I have to select hw:0,2 device.
Another odd thing is that different programs show me different device. For example, Audacity shows me that I have the following audio recording devices:
- HDA Intel: ALC888 Digital (hw:0,1) - HDA Intel: ALC888 Analog (hw:0,2) - spdif - default
The only one that works is hw:0,2.
But arecord shows me (when I execute "arecord -L") the following:
Finally, in KDE system preferences for audio I get that I have 2 different audio devices for audio recording:
- HDA Intel (ALC888 Analog): it is said that it will try first x-phonon (CARD=0, DEV=0) and, if the latter does not work, it will try plughw (CARD=0, DEV=0)
- HDA Intel (ALC888 Digital): it is said that it will try first x-phonon (CARD=0, DEV=1) and, if the latter does not work, it will try plughw (CARD=0, DEV=1)
Where is the hw:0,2? and how can I set the alsa system to use hw:0,2 as the default device for audio recording?
All of that would not be a problem but I also have an ubuntu 9.04 installed on a virtual machine (by using virtualbox) and audio recording doesn't work there. I suppose that it is becase of the virtual sound card is using default devices for playing and recording audio.
I must say that audio playback works fine in both host and guest systems. It is just audio recording.
Whenever I try to play AC3 audio, after a few minutes, the audio dies and never recovers. This doesn't occur with mp3's / etc, although once the audio dies because of AC3, it's gone for good. So this is probably related to surround sound(?).
For those that use Virtualbox on their slackware host and have a windows (xp) guest running. I have tried various settings for sound (Alsa, PulseAudio), the AC97 drivers are installed in the Windows xp guest os, but there is no sound and there is an unknown audio device (in the windows device manager). If I remove the AC97 drivers and use the soundblaster16 drivers in the Vbox settings there is no unknown sound device, but there's still no sound. why I can't get sound working?
I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69 real 9m54.886s user 0m5.536s sys 0m1.740s $ ls -l test-32000.wav -rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?
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 .
The audio configuration sound test and the answer to the question No returns a message that says: automatic detection of sound card did not work. I am not sure what else is needed to diagnose the problem.
I've got no sound. I'm not sure if I should post this in the hardware forum or not because i'm not completely sure that it might be hard ware. Here's the card that's in my laptop though. Raedon HD 4200 - RS880 Audio Device. And yes I made sure my sound was off mute.
I have a fresh install of Natty and i'm having some issues getting sound to work. My laptop has a built in sound card which works just fine. However, i also have a usb 5.1 sound card which isn't working at all. Both devices show up in 'Sound Preferences' but when i select the 5.1 device as the output device sound doesnt work. I ran the alsa-info.sh script and the output can be found here.
I need to capture from my webcam. It has a mic too.I can specify video input device as /dev/video0.I specified input audio device as /dev/dsp2 ( OSS device, corresponding to USB Webcam), Now VLC throws an error, "VLC is unable to open the MRL 'alsa:///dev/dsp2'. Check the log for details".Thinking it wants an alsa device, I specify device as /dev/snd/pcmC2D0c. (got it from kinfocenter and dolphin). Now again an error, "VLC is unable to open the MRL 'alsa:///dev/snd/pcmC2D0c'. Check the log for details.".I try with any device, the same error. I have added myself to audio device so that I can read/write to the mentioned devices.I see no way of switching VLC to use OSS. And I see no information (documentation on net) on it's expected device listing for audio.
When i turn on my computer and log in i get a notification that says "Phonon: KDE's Multimedia Library -- The audio playback device HDA Intel (ALC880 Analog) does not work." and the system falls back to pulse audio.
Also, i noticed that if i wake my computer from hibernation then the HDA Intel device will begin working again.
I read through the comprehensive sound guide with no luck, this behavior seems very strange to me and im not sure what is causing it. I would much rather use the HDA Intel sound device than Pulse Audio.
I use an echo indigo audio card. When I do aplay -l I see this card, and I can ouput audio through it by specifically telling mplayer to use this (alsa) device. Now I want to use this card as default for all audio. At the moment the default is pulseaudio through the built in soundcard. How can I change this? Im running Ubuntu 10.04.
I'm having here annoying "problem" with my webcamera. Everytime I want to use it as a microphone it needs to be switched manually in sound settings menu. It's not a big deal but I would really rather let it be switched automatically like plug and play or something like that.
I can get sound out of my machine just fine, but for some reason, no matter what audio player I use, every time I change the song or pause playing half my speakers will kill sound and it will seem like the sound profile has reverted to Analog Surround 5.0 Output. When I check my sound configuration it still lists 5.1, and I have to select another setting then change it back to 5.1 to get my speakers all functioning again.
I'm running Ubuntu Maverick on an Intel H55 mobo. I have the sound configured to output through speakers on my monitor, via HDMI. That has been working fine. Last night I installed Skype (220.127.116.11) in order to chat to someone back in UK. When I go to the sound devices configuration in Skype, each of the devices (Microphone, Speakers and Ringing) only have a single choice: 'PulseAudio server (local)'.
In order to get my usb-connected phone handset working with Skype I have had to go to the main sound preferences and alter both input and output to '9980 Analog'. This works fine - I can make a Skype test call and playback my own voice. However, all my system sounds now go out on the usb phone handset - also the Skype ring goes to the handset, which is pretty useless because it can't be heard from more than a couple of feet away.
How can I make Skype use the 9980 device for voice in and out, and use the system speakers 'Internal Audio Digital (HDMI)' for the ringing, while leaving all the system sounds to go out on the HDMI output too? I'm sure that I managed to make Skype work much better on an older system (using Gutsy, or Intrepid???). It seems, to me that there is a lack of fine audio control in my system.
I recently installed Ubuntu on my HP Pavilion dv4-2012br and am really enjoying it, except that it is conflicting with my sound card. The only way I can hear some sound is going into System> Preferences> Sound> Output and selecting "Internal analog stereo audio" which makes the sound hollow and not at all pleasant to listen to music. When I mark "RS880 audio device [Radeon HD 4200] Digital Stereo (HDMI)" the sound is not played.
I followed step by step these instructions: [URL] yet the only way to run the audio through the "Internal analog stereo audio. "
Just adding: I used the "Install with Synaptic Package Manager" way to do it. And i'm using a desktop version of Ubuntu.
I have an ASUS M5A78L-M LX motherboard with ALC887 inbuilt sound. The sound is barely audible unless the speaker volume is all the way up, and then it is very crackly. The BIOS is set up to use AC97 sound instead of HD Audio, which doesn't work either.
I have tried uninstalling and reinstalling ALSA drivers but it didn't really change anything.
