Usb sound output with integrated 100W amplif

Hi,
I would like to see a extensible USB audio device with integrated 00W amplifier. I should be able to connect for every room in my house such a device. The audi source schould not be fixed to one computer. I should be able to select different audio sources in a network environment.
or
does something like that already exist ?

I saw a device the other day, and I can't remember the name unfortunately, that allows you place multiple wi-fi boxes in various rooms through the house. I believe the box also had an amp etc. You can then choose to play different music in the different rooms. Hopefully someone else can recognise it

External USB sound device with SPDIF In?

Hi all,
I would like to know if Creative has any external USB sound cards with a SPDIF interface that works with Windows 7. I have an Extigy, and as I know it, it will not work with anything newer than XP.
I need a USB card with SPDIF input to bridge my Astro b.yond 5. SPDIF audio to my 5. speaker kit. For various reasons I cannot change the existing sound card in the computer.
Please help.

I don't know that sound card or application software, but the usual reason for this is that somehow you have reverted to the Microsoft wdm drivers rather than the asio ones you need for multi channel use.
This sometimes happens with some usb interfaces if you have connected the interface originally before installing any drivers. Removing any drivers associated with usb audio and then re-installing them might be worth a try.

No Sound Output with Digital Output Mac

Hi There,
I normally use my Blackmagic card for sound output on my Mac with Premiere CS6. I want to work with the digital output on my current project but when I try switching to digital out under Preferences>Audio Hardware the audio still comes out of the Blackmagic card but not the digital audio out on the Mac. I'm testing with the bars and tone in the browser and my timeline sequence. FCP 7 works as expected when digital out is selected, and I know digital out is working properly on my computer.
Any suggestions?
Thanks!
Gerry

OK, sorry it was that I had to switch audio device under plackback.
Perhaps this should be added to the FAQ under No Sound During Playback, which doesn't include the Preferences>Playback as part of the troubleshooting for MAC.
Thanks!

Intermittent USB Sound Output

I have an Al Macbook Running Leopard, 10.5.8. I just purchased a Monoprice Mini Displayport Male and USB Male Audio to HDMI Female Converting Adapter
http://www.monoprice.com/products/product.asp?cid=104&cp_id=10428&cs_id=1042802&pid=5969&seq=1&format=2
The goal is to output both video and sound from my computer to my audio receiver’s HDMI input then onto my TV and my surround sound speakers. The first time I set up my system I wasn’t getting any sound thru the USB to my receiver. I then plugged and unplugged the cables multiple times and got the sound to work. I didn’t change any settings in my Preference panel. Last night I hooked my computer back up to the cable and it didn’t output sound. Is there a sure fire method to ensure that my USB port is outputting sound to my HDMI adapter?
One other symptom, when I was getting sound out of my cables, I could close the lid of the computer and still get video and sound out. Last night, when I was using the cables and I tried to shut my lid, the computer went to sleep and I lost all video signals.

Hi, Ulyssesbob ,
welcome
first of all, i don't know about the adapter you are using. but here are a few remarks:
1) closing the lid of the MB means that is has to go to sleep. So the instance you quote, that it continued playing video and music, is not normal. it is normal to stop all activity when you close the lid of the MB.
2) when setting up new connections with sound (and video), the system needs a bit (few seconds) of time to recognize things. Once there are multiple output possibilities, the system can chose by itself the one you would like, but a priori, the MB doesn't know which one is the right one. You should check the Syst.Prefs and set it to the one you need. This also implies: if you disconnect, the MB might change the Syst. Prefs by its own decision, since it will not put output to an nonexisting device...
I would try to reset it up, slowly, and controlling every step you are doing by looking at the system prefs settings. Hope this works out. If you still have problems, or your MB behaves strangely, please report back.

Sound output with sound and vibration toolkit

Hi!
Wants to setup a system with two microphones that are connected to DAQ NI USB-9162 and perform a Frequency Response between them where one of them has the undisturbed signal (close in space) and the other the respons (further away). My problem is that I want to send out noise or multitone through labview to an amplifier with internal D/A connected to my USB (turns up as a soundcard in windows). I can not find this option to send out sound in the sound and vibration tool.
Using evaluation version of both Labview and the sound and vibration kit since I wanted to see if it was possible to perform this application with Labview. Feels close but lack the success still.
Best regards
Fredrik

Ok so I have to use the Labview interface instead of the sound and vibration toolkits interface? I see the sound out option in Labview where my card apperas but not in the sound and vibration toolkits interface. Guess I have to add the options for the analysis manually then?
It should be easy to do some modifications if you have some code doing what you want, but not with a sound card. If you have some code just post it. So I can take a look. Note that sound cards do not support all sample rates. But all sound card do support 44100 Hz as sample rate. And newer sound card also higher rates. And how good your setup will be. Will depend somehow on your sound card. But by all means give it a try
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Using iMac sound output with JBP 'Creature' speakers

Am trying to install a pair (set actually) of JBL Creature speakers. I am using the iMac digital audio output which I understand should also serve as an analogue output. However, the sound out of the JBLs is quite muffled, tinny, and low, which leads me to believe that something is wrong. Any clues?
Not sure how Mac Audio outputs work.

HI,
I have the Creature with satellites. One of your satellites should have a plus and a minus sign. That is volume. The bass and treble are on the Creature subwoofer.
The outlet you use on your Intel based iMac is the one closest to the right side on the back.
Make sure your cables are seated properly. They connect "just right". I have found the Creature to have superior sound for such a small system.

No choice of sound output with lightning HDMI adapter connected.

When the lightning HDMI adapter is plugged in, sound is piped through HDMI but I want the option to have the sound come through the iPad speaker, because the mini projector I use has only a 1 Watt speaker built-in, and the iPad sound is louder. Anyone figure out how to choose speaker output?

I don't believe that is possible.
Does the projector have an audio output jack to connect powered speakers?

Continous sound output with variable frequency?

Hi all!
I wanted to output a signal via the soundcard with one variable frequency.
How can I do that?
Thanks
ANDY

Hi Andy
I'm afraid I've only got access to 7.0 & 7.1.
SO Set Num Buffers.vi uses a Call Library Function node to access lvsound.dll.
Hmmm...
I've had a scan around and you could try checking this link
It may give you some clues.
Good luck

Multiple USB Audio Outputs?

Is it possible to set up the mac mini to have multiple USB audio out puts? I'm wanting to use a mini displayport + usb audio > hdmi cable to a plasma for computer use. But is I want to listen to just plain music use USB audio to a DAC into a 2 channel system. So for this system I would need to use 2 USB outputs for music.
Thanks

Sure,
You can output sound through more than one little external USB sound card, but probably not to more than one at a time. You'll have to select the Output in the Sound Preferences each time to switch them, too.
But don't overlook the Mini's internal sound output as one of your 2-channel or 5.1 audio outputs. The 2009 Mini has better audio output than the PPC Mini, that I also had and used an external USB sound card with (M-Audio Transit). Of course, now there are cheap little external USB sound cards that look like a little thumb drive for an added 2-channel audio output. So, I'd use the Mini's internal output and an Optical cable for 5.1 sound out, if I were going to use one of those cheap little sound cards. But you can go the other way, too, if you want, with a better USB dongle (like the M-Audio Transit) for your 5.1 sound.
Please let us all hear how it goes and what path works for your application.
Peace to you,

USB sound card sound drop outs and glitches

Hi there, I have been using a Lexicon Omega USB sound card with my Macbook Pro unibody and have been experiencing a failure when running two programs that try to output sound.
e.g. iTunes will be constantly playing music and another program such as safari pings me when I have a Facebook chat message or if there is a sound when a file has finished copying or i try to play a youtube video at the same time or I play a track in spotify, the sound card freaks out and makes clipped distorted noises then stops outputting sound to the amp and seems to stop receiving a USB signal.
The curious thing is that after reconnecting the usb cable, all is fine again and both programs WILL play simultaneously, so it should be possible?
This is really starting to drive me a bit mad as I cant play music and chat online at the same time without the sound crashing.
I presume it has something to do with what program is assigned to the core audio driver and another program confuses it, like when running Logic Pro which seems to take over the whole sound card for its functions and won't share.
Perhaps there is something in OS X I could fix or change to get round this or perhaps its just the sound card not working properly and not the fault of OS X.
Would be grateful for any advice or if anyone else has this issue.
Harvey

Be absolutely certain that all of your 3rd party software is fully compatible with Snow Leopard - visit the manufs. sites for updates & info until you're current, etc.

Sound Output from Logic Express 8 with new USB Guitar Pedal

Hello, everyone. I am guitarist. I have just bought an effects pedal from Vox called the Tonelab ST, which has a USB out. When I connect it to my G5, Logic sees it okay, and selects it as the audio device in the Preferences pane. The problem is that it shuts off my sound output and reroutes it through the USB pedal. If I hook the pedal up to my amp, I hear both. I tried adjusting the sound output through the System Preferences, but that is okay. If I start a different program (like iTunes) it plays through my system like normal. Does anyone have any suggestions?

You need some pro help. I'm only a stand-in while others aren't addressing your difficulties. I would suggest poring over the manual.
Some thoughts: I have seen demos of folks using multiple output options and switching among them. Me, i'm only using one input (my mixer) and one output (my mixer). I run my guitar into the mixer to record while running other tracks out to the mixer to monitor. When I've recorded a part I play back the entire thing through the mixer. I used a Firewire Solo (which I do not recommend) as the analog/digital converter between the mixer and computer. Now I'm using a little USB gizmo that came with my new Behringer mixer and i address is as "USB Audio Codec" in Logic.
So in Prefereces > Devices > Core Audio I have it set to "USB Audio Code" and this functions as BOTH my input and output. Well: How to get multiple outputs. I think you'll have to go to the part in the manual that addresses "Environments" and add another output mechanism, specificall distinguishing between your preferred output options.
In your above post you say you record something and it "sounds great". How are you monitoring this to conclude how it sounds? Outside of Logic? I asked whether you were routing your playback audio (of your "input 2") and you didn't say. It is routing to "Output 1-2". Does "Output 1-2" in the mixer display bounce up and down indicating output activity? Does the "Master" fader in the mixer display bounce indicating output activity?

Default Sound device with attached USB devices

Hi,
my situation: i've got an iMac 27" with an attached 24" cinema display (using display port and usb). Also i've plugged in a usb headset (headphone with microphone).
Whenever booting up Mac OSX 10.6.4 (also happened to older version of Mac OSX, at least all 10.6.x versions) OSX sets the default audio device (input, output and system sounds) to the cinema displays audio device. No matter what i choose as the default sound device i have to reset it after every boot.
Does anyone know how to come around this? I know i can easily set the device by alt clicking on the speaker symbol in the menu, i know there are tools out there like SoundSource that let me even more easily set the sound device but all i want to have is a default sound device that doesn't get overridden on every boot.
Any help?

All right, I seem to have solved it. The fact that it was only working using plughw: should have tipped me off, but at any rate, this is my working ~/.asoundrc:
pcm.!default {
type plug
slave {
pcm "hw:1,0"
ctl.!default {
type hw

Logitech USB headphones - microphone works but not sound output

Seems like the sound output to my Logitech USB headphone has stopped. The microphone inputs but the sound output is blocked. Could be technical issue with the set but was wondering of anyone else has this problem after the last update to 10.14.0

ChickInVici,
Having similar issue with iPad 2. No volume on Apps or Music (except when using headphones). Just started happening after months of no issues. Have reset/ restored with no solution. Can you provide more detail with your solution? I went to >settings>accessibility>voiceover.....but could not find headphones etc... what am I missing. Could you be more specific on what you changed to resolve your issue.
thanks

USB Sound Card: dual stereo output?

I recently bought a Channel Audio Sound Card Adapter which would channel sound through my computer's USB port. Pretty standard it would allow for Stereo headphone out and microphone input:
http://www.ebay.co.uk/itm/USB-2-0-Virtual-7-1-Channel-Audio-Sound-Card-Adapter-3 D-for-XP-Windows-7-Mac-/321480885369?pt=UK_Computing_ComputerComponents_SoundCar ds&hash=item4ad9c10479
I opted for it so I could control from my menu bar where the sound was being directed: http://www.cnet.com/uk/how-to/how-to-quickly-change-audio-output-in-os-x/
However I do not need the microphone in, but do need a second stereo headphone out and would like to know if:
a) A USB adapter exists that will encompass two stereo headphone ports, not a microphone?
b) Whether OS X will be able to distinguish the two so I can control which headphones are in use at any one time from a single USB Sound Card dongle? (note: I am not looking for a Y splitter)
I have read of some OS X software called "SoundSource" from RogueAmoeba, but this has been retired - it would allow for me to flip the microphone port so it would transmit sound, even through the microphone socket, I might have been able to get around it like that? Is there anything else that may be available that could do the job?
Also, I was wondering, if I had to get another USB Sound Card, could I use a USB splitter so that I could plug two USB spun cards into one port and with no loss of quality? USB ports are a premium on my computer.
e.g.

Hello,
I'd avoid the bus powered 4 port adapter & get an AC powered 4 port hub...

Is Creative Sound Blaster Audigy 2 NX USB sound card compatible with Dell deskt

Im considering buying the Creative Sound Blaster Audigy 2 NX USB sound card to use with a Dell desktop XPS 40, but recently read a forum message on another page that there was a issue with installing on a Dell Tower but no problems with installing on a laptop
any help is appreciated if there are any compatibility issues with using this sound card on a Dell desktop, Thanks
the main reason I would like to upgrade to this card is so my pc doesnt use the integrated audio which Id like better quality performance with a sound card and also dont want to install a internal card on the system

joaolfb,
Audigy 2 NX will need to be connected with the power adaptor inorder to run. USB will not be enough to sustain the power consumption of the sound card.
