Ubuntu Multimedia :: Lost Sound (Mute Without Mute) Until Reboot?
Oct 15, 2010
After I listened to the audio program on the Google Chrome, I downloaded the MP3 to listen again offline. When I clicked on the downloaded MP3 file and using Totem to hear on my computer, there is no sound. I checked the sound preference, there is NO MUTE.
I restarted computer, clicked on the MP3 file with Totem, I can hear. I can hear the sound on ...... Which process should I restart without reboot computer. I'm using Ubuntu 10.10. Here is the output after execute command "sudo lshw -c sound"
I have experienced 4 or 5 times a sound-muting bug. Suddenly speakers stop working (usually not in in the middle of something musical but when there is no sound playing) and does not work again until I reboot the system.
My Compaq Presario F700 laptop has Conexant HD-Audio SmartAudio 221 (checking from my Windows partition). I had everything working just fine until yesterday when I attempted to manually install an alsa-linux package that I downloaded sometime ago. Although the .deb package failed to install, it seems it messed things up and now there's no sound. The speaker icon shows "All mute" and I have no clue how to fix this. How do I 'unmute' it?
when i select mute on the volume control in the ubuntu control panel the sound gets muffled but does not mute. also if i plug in headphones the headphones are fine but the speaker sound just goes muffled not off completely as expected. this happens in iplayer and videos. rythmbox works fine. running ubuntu 10.10 64bit on samsung r720 and lspci | grep udio returns

i have a problem in my notebook, its can make a sound i use the slackware 13 edition for my notebook i have upgraded my alsa-base on my laptop to alsa 1.0.22 on my slackware 13. i have follow the instruction tu active my sound device with command:
#alsaconf #alsamixer #alsactl store
but, the sound still wouldn't active, this is the result of my lspci -v on my slackware 13 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev
In the last week, I noticed that my compaq 6710b physical controls for volume control/mute stopped working correctly. The volume control is not working anymore and the mute "unmutes" itself after precisely 1 minute.
I was wondering:
1/ did an update modify anything
2/ is there a way for me to know if the problem is physical? like a physical signal sniffer of some sort, or a log that indicates that I pressed mute
3/ Am I alone? and if not, does anyone know of a workaround?
Am running 10.4 Linux vaucher-laptop 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 08:03:28 UTC 2010 x86_64 GNU/Linux
I'm just installed 10.04 on a new Gateway DX4300. The integrated sound card is a Realtek AC1200. Sound works great, however, I'd like the rear input to mute when I plugin my headphones in the front input. Where can I configure this? Here's some basic information:
I don't want to monitor my inputs. In other words: My microphone input plays through my speakers, adding a lot of undesirable noise from the mic. I can mute the mic inputs in alsamixer and/or in the Pulse volume control. This works to get the mic out of the speakers--but it also mutes my mic entirely, so I cannot record audio or use Google Talk. I want the microphone muted in my output, but available to my apps.
(I try to get on the Pulse bandwagon but it is so hard--I thought this was exactly what it was supposed to do, give easy mixing control over inputs and outputs. But I have to search for "fixes" with every single Ubuntu release for two years now, ever since it was first included. Ok, venting over, time to get it working!)
I've been bashing my head against this problem for weeks now. The problem is that my external speakers are not being muted when I plug in headphones. I get sound through both the speakers and the headphones at the same time. This is happening on every Linux distro I've tried so far on this box, but in Windows everything behaves as expected. I've tried every option I have in both alsamixer and the Gnome sound preferences, to no avail.
Curiously, if I mute any one of the audio channels or toggle the headphone switch in alsamixer, all sound output is muted, to both the speakers and headphones. The audio chipset is a Realtek ALC888, on a Gigabyte GA-770TA-UD3 motherboard (6 jacks, optical and coaxial S/PDIF out). I must've tried a dozen different models in /etc/modprobe.d/alsa-base.conf, and none of them seem to make any difference at all.
I have a lenovo thinkpad and my internal microphone works only when i connect another mic through the jack. Even the mic mute button present on my laptop is not working.(There is no such problem on windows se7en) Earlier, even an external mic never used to work. After some searching i added "options snd-hda-intel model = thinkpad" to my alsa-base.conf file. And then the internal mic started working only when an external mic was connected.
when i type "cat /proc/asound/card0/codec#* | grep Codec" i get: Codec: Realtek ALC269 Codec: Intel G45 DEVCTG
I looked into the HD-Audio-Models.txt but couldn't locate the exact model for ALC269 so i searched online and decided to put model = thinkpad as i'd mentioned earlier. But The alsa-mixer shows card to be HDA Intel and chp as intel g45 devctg. Moreover, even this partial working of mic(s) is when i choose the input source in the alsamixer to be front mic and not int mic.
I'm using mplayer with shell-fm, in my shell-fm.rc I have the line extern = nice -10 mplayer -really-quiet -ao jack -cache 512 -noar -nojoystick -nolirc -noconsolecontrols -nomouseinput -demuxer lavf -lavfdopts format=mp3 -af-adv force=5:list=resample -af resample=44100:1:2:extrastereo-1.5 - This to me at least produces a pleasant audio output but despite the -really-quiet option mplayer is still outputting text, generally something like [mp3 @ 0xa3f5380] max_analyze_duration reached I've also tried the -msglevel all=-1 option and had a play with the MPLAYER_VERBOSE environmental variable, all with no joy.
I have a Toshiba Satellite L650 with a Conexant 5069 sound card, and when I plug in my headphones the built-in speakers don't mute. I already tried adding options snd-hda-intel model=lenovo to /etc/modprobe.d/alsa-base.conf (I also tried auto, toshiba, thinkpad and ideapad). This is the alsactl init output: Unknown hardware: "HDA-Intel" "Conexant ID 5069" "HDA:14f15069,1179fd12,00100302" "0x1179" "0xff1e" Hardware is initialized using a guess method.
I am struggling with a problem with the volume control... when i try to adjust the volume with the sliding bar i can not do it. If i put the scrollbar to the 0 position, it is muted. when i move it to anywhere else, i get the full volume. From other programs like vlc, i can adjust the volume with no problem.
I'm on an IBM Thinkpad X60. When I plug either headphones or external speakers into the headphone jack (whether on the docking station or the laptop itself), the laptop speakers aren't muted. I can hear sound coming from both simultaneously. I've tried editing the /etc/modprobe.d/alsa-base.conf in all kinds of ways, my most recent attempt being to add the line:
Code: options snd-hda-intel model=thinkpad but still with no success.
I'm using 10.04 with the 2.6.32 kernel. I tried installing the .34 kernel with no better results, so I switched back.
I usually need to turn on my computer in a library or a classroom and it is kinda embarrassing to cause sound at the startup. Is there anyway to introduce a script to mute the computer before it creates the startup sound?
I think this is a bit of a complicated problem so bear with me while I explain it. I'm using an HP Laptop with Ubuntu 10.10. The laptop has the touch buttons for mute and volume up/down, and I use them all the time (at least when I was on Windows). I've very recently switched to Ubuntu and now those keys are causing problems with a game called Minecraft. Basically, when I'm playing it and use those keys, it brings me out of full screen (if I'm using fullscreen) and then seems to mute like it should, but the problem is, it doesn't UNmute when I press it again. The lighted button on the laptop goes back to showing its unmuted, but the game still has no sound. I've tried messing with the sound settings inside the game, and doing all these weird combos of when I mute/unmute and all, nothing seems to help. I usually have to restart the computer to fix it, but then if I use the button again, it does the same thing.
P.S. does anyone know of a way for these buttons to NOT interrupt full screen? I had the same problem with it interrupting fullscreen apps on windows, but then I used a program called 3RVX and it fixed it. Is there anything like this on linux?
The volume on my computer randomly mutes/unmutes itself rapidly at unpredictable intervals. sometimes it works fine, other times it does not. I cannot find out what the problem is. I have never had this problem until recently, and this problem has surfaced in ubuntu 10.10, 10.04, 64 and 32 bit versions of the operating systems. I have used this hardware setup for a year before this problem ever surfaced. My hardware is installed and working fine, I just cannot figure out why this is happening. Does anyone know of some commands I can use to find out what is causing the volume to mute/unmute itself?
I didn't (maybe still don't) have ALSA loopback so I could record streaming, so I upgraded ALSA following these instructions:[URL].. The only part I didn't follow verbatim was the final step:
Quote: Allrighty, time to load it. But before that, shut down all audio apps (including firefox). Once done, do this:
Code: sudo alsa force-unload sudo modprobe snd-whatever-module-you-need sudo modprobe snd-aloop I was unsure about "snd-whatever-module-you-need" so I decided to reboot.
When KDE was just about to kick in, I saw a lot of new text I had never seen before scroll past very, very fast. Then it stopped and I could see it had something to with ALSA, but I couldn't really read anything. KDE started and... now I have no sound. I checked kmixer, it looks normal. It doesn't seem to be mute. I ran alsamixer in the command line, it doesn't seem to be mute either. I ran Kcontrol and checked the audio section, couldn't figure anything out. Here is the output of lsmod BEFORE the upgrade:
I found a curious issue with my new Dell XPS 8100. On my old Inspiron, as soon as I plugged in the headphones they muted the speakers. That's how it should be, because you listen to headphones so you don't blast your music all over the room. But now, on the 8100, the speakers still blast even if the headphones are plugged in. Headphones Also work, so they're getting a clear signal. It's just simultaneously being played in the rear speakers too.
I installed an Asus P7P55D PRO motherboard and now I can't mute Master channel with alsamixer, even not using KDE mixer. Probably ALSA doesn't support properly, despite I upgraded alsa libraries (alsa-lib-1.0.21a). The key to increase or decrease the volume through keyboard works fine, but the key for mute is not working. These are the alsamixer values:
Card: HDA Intel Chip: VIA ID 444
I also used alsaconf command and it detects a snd-hda-intel board. I have a G15 keyboard and I even tried to make a shortcut with KDE mixer, but it doesn't work. Is there any way to solve it or have I to wait for a new version of alsa? I use Slackware64 13.0 with kernel 184.108.40.206.
