The motherboard integrated soundcards usually have much more noise, noticeable at higher gains, due to proximity to other components and not being shielded. This noise can be very unpleasant, and if you have good speakers/headphones, it's even more noticeable. If you care about the sound quality and/if you have good quality speakers/headphones, you should ...

It depends on what hardware you have in the computer, but there usually is a difference between speaker and headphone ports - specifically, relating to the max/min speaker/headphone impedance values you can use with either port. Certain sound cards, for example the Auzentech X-Fi-Forte, include a built-in headphone amplifier on the headphone port. Taking a ...

I'm using the motherboard's sound in my HTPC, with optical output to my receiver; it does 7.1, DTS, AC3, and other three letter acronyms. I also game on the system, and have no noticeable performance impact from not having a "dedicated sound processor" or whatever the marketing folks are saying these days. I find that sound perception is subjective, and ...

A single device outputting to multiple devices seems to work OK. It changes the electrical characteristics (impedence changes, but the tolerance of most devices is actually quite wide) and could theoretically cause damage, but has always worked fine for me. However, multiple devices outputting to a single device is different. That's a situation where ...

The 5 audio jacks you quote is the important thing, not the number of speakers. It refers to the audio jacks on your motherboard or sound card, not the plugs from your speakers. If you have multiple audio output jacks on your motherboard/sound card then you have support for surround sound (providing the correct drivers are installed) The standard jacks ...

Find your card with cat /proc/asound/cards and then create /etc/asound.conf with following: pcm.!default { type hw card 1 } ctl.!default { type hw card 1 } Replace "card 1" with the number of your card determined above. Alternatively, you can change ordering of your cards so your USB card will be card 0 and it will work ...

It isn't your screen causing the noise per se, it is caused from one of the controller chips (for either the PS/2 or USB) having interference with the sound chip. Some motherboards are very badly shielded and there is just nothing you can do to fix that, all I can really recommend is purchasing a PCI / PCI Express sound card and using that instead.

The audio ports detect that something has been plugged in by monitoring for a change in resistance across the port. When nothing is plugged in the resistance is infinite, but when a coil is plugged in (speaker or mic) there is now a measurable resistance, and the computer pops up and asks you what it is you plugged in. EDIT: I've been digging, and ...

As pipTheGeek stated, another option to the electrical resistance measurement is a mechanical switch. Switch pushed down - something's plugged in. You can test this by plugging a Y-adapter or size adapter into the jack. If the jack acts like there's something plugged into the port, you have a mechanical switch. The adapter won't make any connections ...

USB Headsets are soundcards. Only 1/8" jack type headsets go through the onboard soundcard. Source: regularly configuring PulseAudio on Linux.

It might be some odd power issue. The only solution to that really though is external speakers. The sudden albeit small power drain from a loud sound might be a problem.

Found it. Open registry Editor with elevated privileges Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0000\GlobalSettings Change the value EnableDynamicDevices to zero. Restart your system.

this is the method for selecting default sound card in Alsa. You may want to install Alsa for this method to work if you are using Pulse Audio. cat /proc/asound/modules will list your sound modules .The output of the command will be like this (eg): 0 snd_hda_intel 1 snd_usb_intel you can pretty easily understand which one is your usb ...

It may well be a DPC latency issue, which can be caused by a variety of things including, sound cards, network adapters, drivers etc. Unfortunately, tracking down the cause of these problems is no easy task. There is a utility DPC Latency Checker that can help you check for latency and there is a wealth of documentation on the same site. If you have ...

No, soundcard (and other) hardware is managed by kernel, and correct modules must be loaded. Maybe livecd loads modules which now are not installed yet. If you are sure that sound is not muted and alsa is running (sudo /etc/init.d/alsa start) look at ubuntu help starting from "Is the system recognizing your sound card?". You'll find how to know if your ...

I have experienced this with my HP Pavillion dm4 as well, and it drove me nuts. The reason this occurs is that the audio chipset in some HP laptops is configured so that the headphones are used as a "communication device" and the speakers are used to play other sounds. Whenever you use a communication program, like Skype or Google Video Chat, it sends the ...

Are you dual-booting the machine? If you are can you test the sound in another operating system? with crackling 9 times out of 10 it's either the output cable/connector or the source of audio (spotify, iTunes etc.). If the crackling persists in Windows 8 and not in another OS then it may be a driver issue and you should email Realtek to see if they will be ...

I work part time in a recording studio, and this is very common on computers with no external sound card, audio processor or recording interface. Electrical interference can occur in or around the motherboard, tower, cables, fans and pretty much anything electrical in or connected to your computer. This interference can manifest itself in scratching or ...

I solved the problem: The sample rate in control panel/sound has to be the same as the sample rate in Asus Xonar Audio Center. In this case I had 44,1 kHz in Windows and 96 kHz in the Xonar Audio Center.

The file your looking for is located in /usr/share/alsa/alsa.conf. Its not called alsa-base.conf just alsa.conf All the relevent text is in that file just run sudo nano /usr/share/alsa/alsa.conf change the default sound card to 1 or whatever one you prefer obviously 0 is default so not that one i also deleted the # from the line that says... load ...

Wild guess: the noise is loud enough to make some automatic head parking mechanism in your laptop kick in (this is the anti-shock technology which is supposed to protect the drive if the machine is dropped). On the other hand, if that was the problem I can't believe you wouldn't have continuous problems using your lappy in a car/train/plane too (is it ok in ...

A solution that bypasses this problem (assuming the jacks are free) is to plug Computer A's line out into Computer B's line in, and then Computer B's line out into the speakers; this requires Computer B to be on for either to produce sound, but shouldn't damage any hardware.

From this forum thread: USB headsets basically have a USB sound "card" integrated. For the Logi USB headsets that's a small unit integrated with the cord. You could pull your soundcard out of your PC and the USB headset will still give you sound. Which makes sense.

Are you sure that you're losing quality because of the 3.5mm -> 6.3mm adaptor? If it's the one that came with the headphones it will be made to the same high quality as the headphones - particularly if it's from a company link Sennheiser. I don't recall ever seeing a computer sound card with anything other than 3.5mm sockets. While there are probably ...

As other have already mentioned, media players normally have the option to use the default audio device or any other in its preferences settings. If you are using Vista or Windows 7, you can also set a secondary audio device to be the default communication device (look in Sound Properties), so you can have normal sound coming out of your speakers, but have ...

Try setting up a stream with VLC, such that it runs on your desktop and your laptop. Then let your desktop play the audio through the speakers and mute it on the laptop. Here's a nice tutorial for setting up the stream from WikiHow First, you need to download VLC. Install it on each computer that you want to be able to watch the streams. Run ...
