Sound from 1 application (solved)

I've got sound working on my Arch install (intel_8x0 driver) but sound still only plays from one application at a time. I'm up to date with Alsa 1.09 which I thought solved the issue. Any ideas?

> I do not think it is right to be making any judgements
> about where the ALSA development is headed
What do you mean? What such kind of judgement did I do? All I said is that software mixing does not work, it should have worked (sorry, but even half-assed old OSes like QNX, OS/2 and BeOS, Windows95 have automatic software mixing just fine) and that there was a talk that 1.0.9 WAS to bring automatic software mixing, but it didn't.
Last November there was a huge thread with me, Linus and the alsa guys discussing this very thing, with Linus pretty much asking for that same thing too. If Alsa guys want to be taken seriously (and they do want to, because they wanted to replace OSS in the kernel, which DOES have software mixing) they better get their act together. The lack of automatic software mixing is simply unforgivable after all these years of Alsa development. We are talking about ~80% of linux laptop users today can't play more than one sound at a time and many cheaper PC systems can't either (all the AC97 cards for example)! This is pathetic. I am sorry, but it is! This is 2005, even the Amiga could do automatic software mixing. (most of the users don't even know what's wrong, they think it's their distribution's fault!!!)

Disable all sound from application

Hi,
I need to disable all sound or volume from my application upon a button press. I have a html component within my app that i need to be muted, for example if the user loads the youtube website and selects a video, the video should play but without any sound?
Can this be done?
Cheers

I am having a similar problem....didn't recognize it until today.... I wasn't getting any sound out of the right side of my headphones....Unplugged them....wasn't getting anything out of the right front speaker....Hmmmswap them around...speaker is good... Take apart the base unit for the Inspire 5400....nope, that's looks ok....plug it all back in....check wiring...plug everything in correctly....test speakers with Creatives software....all sound is now coming out of the front speakers....nothing out of the rear.... I can't figure it out....it is getting late...any suggestions would be greatly appreciated!

I am not getting any sounds from Applications or Web Browsers, but i am getting alert sounds.

I've tried everything: Restarting my computer, audio MIDI settings, reseting PRAM, opening garageband :l Nothing seems to work! This is really anoyying. I've looked at all the forums about this and i've tried everything it says, and no luck. Please help. And its weird because my computer is not muted and when i turn on the computer the startup sound comes, then i go into iTunes and play a song, but nothing plays, I just hear nothing but error and alert sounds! Please Help!!

Hmmm, only thing I can think is some extension not loading or borked, open System Profiler, or whatever the name has changed to now, check Software>Extensions & see if all the myriad Audio ones appear to be loaded & valid...

When i play a video or movie i get a buzzing sound from the speakers. how do i solve this problem?

I get this buzzing sound from my speakers when I play a video, or movie either from the internet or playing a DVD. What can I do to solve this problem

A: There is no such thing as an unlocked iPhone 3Gs in the United States. ALL iPhone 3Gs's sold in the US are locked to AT&T. AT&T will NOT unlock iPhones, therefore it is not legitimately unlocked.
B: Sprint is a CDMA network as others have mentioned. They do NOT use SIM cards. The iPhone 3Gs will NEVER work on Sprint. Ever. It's not physically possible.
Either your Uncle misunderstood or he was mislead. Send it back and tell him to get his money back. Buy an iPhone in India from a supported carrier.

Playing sound from multiple applications?

Hi, I recently started using Arch and I'm loving it but I have one problem. My ALSA can only play sound from one application at a time, so I have to use pulseaudio for the others. But pulseaudio doesn't recognize my mic so I can't remove ALSA. ALSA just says "device busy" or something. And yes I tried to search before posting but didn't find an answer.
Thanks

[Solved] No sound from VM (Windows 7) on qemu with virt-manager

I posted this in Newbie corner,
https://bbs.archlinux.org/viewtopic.php?id=176131
but let me re-post here becase it is about sound matter.
I have installed Windows 7 (64bit) on qemu with virt-manager.
It seems that audio works fine inside the guest os, but I can hear no sound.
[Guest]
Guest os: Windows 7 (64 bit)
Sound driver: ich6
Console: Spice (VNC doesn't work.)

According to
https://bbs.archlinux.org/viewtopic.php?id=157604
I did as follow before launch the VM, but it doesn't solve the problem.
export QEMU_AUDIO_DRV=alsa
What shoud I check and do?
Followings are some additional information:
* If I put the same command above
% /usr/sbin/qemu-system-x86_64 -name win7qemu002...
It produces error.

* According to the someone's discussion,
I added my user to kvm group

or edited /etc/libvirt/qemu.conf, but they don't fix this errors.
% sudo vi /etc/libvirt/qemu.conf
- #user = "root"

* Everytime I launch the virt-manager,
a dialog "Authentication" pops-up and asks
for my user password (not root password).

Self reply.
Finally, I got to hear sound from windows 7 as guest OS.
I gave up to use virt-manager and launches OS image by command line
like follows.
% export QEMU_AUDIO_DRV=alsa
% qemu-system-x86_64 /mnt/win/win7qemu002 -cpu kvm64,+nx -enable-kvm -m 1536 -soundhw hda -usb
Then, sounds works good.
# However, the quality is bad because of heavy CPU load.
Virt-manager may make things complex..
Sorry for the duplicated post.

Have you got notifications muted ? Only notifications (including games) get muted, so the Music and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad above the volume switch, or via control centre : swipe up from the bottom edge of the screen and it's the right-most of the 5 icons in the middle of it (if the icon is white then it's 'on', tap it to turn it grey and 'off'). The function that isn't on the side switch is set via control centre instead : http://support.apple.com/kb/HT4085

Dv-1015ea- no sound from TV via HDMI- solved

hi guys
i had a problem with sound from TV via HDMI from my DV5- 1015ea. i had gone through almost all the threads but the solution was pretty similar. here is how i solved it.
i have windows 7 ultimate 64 bit.
go to device manager and open Sound, video and game controllers
it should bring IDT HD audio CODEC (or appropriate driver/device name,depending on your machine) and
NIVIDIA HD audio (again dependent on your machine).
now right click on each one in turn and just select update driver.
after its done (dont restart your pc yet, even if it asks you to)
right click on the speaker icon/ audio icon on right side of your task bar
open playback devices
a new playback device should be there, called something along the lines "NVIDIA HDMI output" which should have a tv icon next to it
single click on it and select SET DEFAULT just under the icons in the window of playback devices.
now try playing something on PC and you should be able to watch and hear from your tv.
**this was done with hdmi connected to the TV and the tv should be displaying the same as your PC screen.

If I understand you correctly, you have installed all required alsa packages and tried to configure. What doesn't work is attempting to push up the volume via alsamixer/aumix etc., unmuting also does not work.
Am I correct?
If so, you may have a similar issue to what happened to me a ways back. Is your current kernel up to date? The problem I had involved the fact that my sound card (though it was extremely common and, well, sh*tty) was affected by a feature regression in the ALSA code and an incompatibility with kernel in what was then [current]. I had to wait for the kernel to catch up to ALSA to do anything, but the regression had to be fixed before I could do anything useful.
Moral of the story (also known as the 'tl;dr' or 'too long; didn't read' version) - Try updating your kernel if all else has failed. If nothing useful comes out of that, try searching the ALSA site.

Can't get sound from Insignia BT headphones w/ BT-equipped dv3t

Both are brand-new, I charged the headphones and downloaded the updated drivers from www.broadcom.com (actually Vista seemed to do it automatically) and the device is paired but I can't get any sound out of it (it's turned on:-)).
Under the Playback tab in the Sound control panel there are three items:
Speakers: Bluetooth Hands-free Audio
Speakers and Headphones: IDT High Definition Audio CODEC
Independent Headphones: IDT High Definition Audio CODEC
All say they are working, but when I test the sound of each one I only get sound from the notebook speakers using the second option. The only weird thing I can think of is that I had the USB adapter plugged in when I downloaded the drivers, so maybe it downloaded drivers designed to work through USB? (I can't get sound with the adapter plugged in, though, either).
Any suggestions welcome, I really want to get this to work and not have to send the headphones back to seller (which is what Insignia tech support told me to do).
P.S. I know I have BT turned on because I'm also connected to a wireless home network, they go together.

Hello again,
oops, I must have missed your last message... sorry for that!
I have to say, that I don t have my digital sound system that long, that I can answer this question for sure. However...
You re right, that it should be possible, although I wasn t able to find a way to do that... yet... Somewhere (don t know if it was this forum or another place) I ve read, that the SPDIF support for Windows Vista isn t that nice at this time... perhaps a new driver will solve this
Furthermore... I don t use the Media Center that much. So I don t even know if there is any option to set the output device (within the application Media Center). That would be important to realize "the best of both worlds". Explanation: If you want headphones support, you (always) have to leave the Speakers device as default. Other applications (such as Winamp,...) allow us to set the output device (in Winamp for example you can set it under the preferences Output -> Directsound device) to the SPDIF device, although we have selected "Speakers" as default in the control panel... nice, isn t it's For sure... if it would work...
That way you don t get a(n) AC3/DTS signal via SPDIF... so, if you use Windows Vista (I can't answer your question related to other operating systems, because of my newly purchased system -> I haven t used it on XP) the only way that I know ( til now) is to select the SPDIF device as default...

My mac desktop will not provide sound from internal speakers. when I go to audio devices window it only shows airplay. How can I get internal speakers back.

My mac desktop will not provide sound from internal speakers. When I go to audio devices window it only shows airplay. How can I get internal speakers back.

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Run Software Update and make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

Thank You

Hi @satyakam
Welcome to the HP Support Forums!
I understand that you are enjoying your sound from everything today. I am happy to help.
If you have a sound application installed along with your sound driver, then I would check the settings for the speakers and headphone in that application.
Then I would make your headphone the default device when it is plugged in.
To make headphone as the default device
1.    Click on Start; Go to Control Panel.
2.    Click on Sound.
3.    Switch to Recording.
4.    Select your microphone/headset as the default device.
5.    Save the changes by clicking on OK.
Also you can Uninstall and re-install your audio device drivers, to do that:
1.    Click on Start; in the start search type “devmgmt.msc” without quotes and press Enter.
2.    Expand Sound, Video and Game controllers.
3.    Right click on the audio component and then click uninstall.
With the driver uninstalled then download and re-install the driver from:
HP Pavilion g4-1121tx Notebook PC Drivers
Just be sure to select the correct operating system from the drop down, and click next, which will refresh the list of drivers below.
Let me know if that helped at all.

SB Audigy 2 ZS Platinum - no headphone sound from the front pan

Hi all,
I had replaced my old broken Asus Mobo with the same type. After all hardware was reconnected to the new mobo I have noticed the front pannel headphone output doesnt work.
I have connected the card and the panel with the proper cable, the pannel seems to be powered OK. I even connected the card and the panel with the internal firewire cable.
The only difference is I have this time installed the drivers from the Creative website, whilst I used the bundled CD with previous installation.
Would that prevent me from hearing the sound from the headphones?
Will appreciate your suggestions,
Greg

Hey Ridenthatide,
?
I have the same problem as you. My system is MSI 865 PE motherboard and XP Pro SP3 with Audigy 2 ZS. I have reinstalled my system numerous times before and never had any problem, until this time....
?
- Format HD, install win XP, install SP3. Install Audigy 2 ZS driver and application from CD. Sound works.
- Install card's latest driver downloaded from Creative. NO SOUND!
- Device Manager shows everything ok. But control panel -> 'sound and audio devices property' has the device volume bar grayed out. Looks like system doesn?t recognize the card somehow.
- Install the latest application (organizer and other stuff), to no avail.
?
I tried to move the card to a different slot. After bootup, windows recognized new hardware installed, and started installing driver (I chose 'let windows auto search'). And sound came back. But if I re-install the latest driver again, the sound will go away.
?
I don't think moving card to a different PCI slot is an legitimate way of solving the problem, and problem still exists after the move. This has been really frustrating.

No sound from speakers, only subwoofer after restore to factory

I recently restored an HP pavilion dv7 back to factory settings using the built in hp restore. When it came back, sound will only play through the subwoofer. When I do sound tests, I hear both channels play, but they play through the one "triple bass reflex subwoofer" on the bottom of the laptop. Nothing coming from the two speakers in the front at all.
I have uninstalled the IDT drivers multiple times using the current drivers, the original drivers in the swsetup folder and many drivers in between from HP's ftp site. No luck. I'm pretty much out of ideas. It's clearly a software or driver issue as they worked before the reset but I have no idea what else can be done about it.
HP tone control is installed, the beats audio panel is visible, IDT audio shows up in appwiz. Ive seen a few forum posts about this same issue but nothing that ever seemed to get resolved.
Any ideas? I've included some screen shots of what I'm seeing

Hi @etainw ,

I have looked into your issue about your HP Pavilion dv7-4000 Notebook and issues with no sound from speakers, only subwoofer after restore to factory. Here is a link to troubleshoot the Subwoofer on Beats Notebooks. On the Enhancements tab, select the Bass Boost option, and verify the device driver is Enabled, this should help.
Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system at the time of purchase.
Thanks.

No sound from TV when using HDMI from HP Envy Ultrabook4 despite downloading drivers

Problem: When using an HDMI cord from my HP Envy Touchsmart Ultrabook 4 (4-1105dx)to connect to my TV to view movies, the video appears on my TV screen, but there is NO sound from the TV. Instead the sound comes from my lap top.
Troubleshooting: I have looked under Sounds in the Control Panel, but the only choice listed is Speakers & Headphones IDT High Definition (which is the default) and does not allow sound from the TV when using the HDMI. I have also tried to download Driver and Audio Graphics, but wasn't sure which one & the ones which were downloaded have not solved the problem.
Can you assist me? Which is the correct Audio/Graphic Driver to download? Or is there another possible reason why I cannot hear sound from my TV when using the HDMI to connect to my lap top?

Hi,
Please try this first to enable Speakers in Playback devices as follows:
1. Right click speaker icon (bottom right hand corner)
2. Select Playback devices
3. Right click HDMI sound
4. Enable it
5. Click Apply/Ok
Regards.
BH
