USB Sound Problem

I'm having a problem with my Bose USB sound system that has just recently developed. The system is plugged directly into the back of my Mac Pro desktop so it's not going through any hubs or secondary systems. When I first start my computer the sound works just fine. But after about 10 to 15 minutes of use the sound stops completely - as if the sounds have been turned off. If I boot into Windows 7 using Boot Camp, the sound system there works just fine with no problems at all, so I do not believe this issue is hardware related but is something associated with OS X.
This all started recently after installing Tinker Tool and then realizing that their latest version is not compatible with Snow Leopard. I followed their directions and told Tinker Tool to restore the previous settings and then I removed it from my system. Now, I'm having this USB sound problem. I think it's highly probable to be the cause of my problem.
Is there anyway to reinstall the USB drivers in OS X without reinstalling the entire OS? Or, is there something else I can try to restore the USB function to Snow Leopard? Many thanks for any tips or suggestions.

They are plug and play.
I did try unplugging all of the USB devices and then powered off the computer and unplugged it for about 5 minutes as I heard that that sometimes solves USB problems. However, upon reconnecting the problem returned. All other USB devices seem to be working normally - it's only the Bose sound system. I tried plugging it into a different USB port in the back of the computer but the problem continued after about 10 minutes. Therefore, I am convinced this is not hardware related.
At this point I am thinking I need to reinstall OS X Snow Leopard to undo whatever Tinker Tool damaged. Is it possible to just replace the USB drivers in OS X without reinstalling everything?

IBook (Dual USB) Sound Problem

The item:
iBook Dual USB, 800MHz, 32 VRAM, CD-ROM,
partitioned HD with OS 9.2.2 & Tiger.
I have installed OS 9.2.2 on the smaller partition via FireWire using Apple's OS 9.2.1 install CD + OS 9.2.2 Updater from Apple's website.
Sound works perfectly in OS X environment.
The problem - OS 9 environment (Booted into OS9)
Great 'Bong" when it boots - BUT - NO SOUND after that. None. Silence. No System sounds. No AOL login sound. No iTunes sound.
All 'sound' related settings are properly adjusted. Nothing is 'muted'. Platinum System sounds are selected. Finder menu blinks to indicate that there should be a noise - but all is deadly silent.
Control Strip Sound menu slider is almost at bottom. Adjusting it UP results in menu blink - and it returns to it previous position.
Sound volumne slider in Sound Control Panel 'snaps' back to the far left when moved to the right.
Sound Control Panel / Input menu shows the following warning:
"The settings for the sound input source cannot be adjusted becasue the device is in use by another application."
I have no other sound-related software installed. No device using the sound port is present. It's a 'naked' OS 9.2.2 install + AOL 5. It acted the same way BEFORE I installed AOL.
What must I do to make this little beauty make the proper sounds, please... ?
Your successfull suggestion will have me singing your praises.

I bought myself Creative Inspire t600 5. surround system. Cool. I was very happy. I?needed only to buy a sound card?working with 5. because I have a notebook DELL INSPIRON 50 who has only 2 canals. So in order to be everything beautiful I gave $70 for Usb sound blaster 24-Bit external. And from that time the problems began. In short :? I was using Vista but I found out that it wont work with this soundcard. The first problem : Didn`t identify the device. I tried with several drivers... Nope. No sound card with Vista.(This problem seems to appearance with many owners like me)?I pluged the usb soundcard in my old pc running XP and it worked . PERFECTLY. So I removed Vista from my notebook and intalled XP. This took me whole day to rebuild all my software. Finally it left to set up the sound drivers. The cherry of the icecream. Aaaaand ..... **bleep**. When I play?any track it CRACKLES. Again problem appearanced with many here. I tried to find out here what is the problem but unfortunately as u can see my english is quite bad?so I cant understand?what I need.I really like Creative but if they cant manage this problem I will?no longer buy their stuffs??JUST PLEASE SOMEBODY ANSWER ME IS THERE ANY SOLUTION FOR THIS OR NOT.

Problem with SB1240 USB sound card

I'm pulling hair here! I've just bought a SB240. Windows (XP Pro, SP3) detected it and I can select it fine for listening. But when I open Sound and Audio Device Properties and select Sound Recording/Volume, I see the Capture panel with the three inputs, but all the controls are greyed out and immovable. I also use the application "Total Recorder" by High Criteria, in which I can select the SB240 device but the only input line it sees is SPDIF Interface.
I'm stumped. Can anyone help?
John?

&Re: Problem with SB240 USB sound card
Thank you. I did a complete uninstall, including the device itself (from Device Manager) as well as all drivers and any SB related software. As recommended by Creative, I had previously installed the driver software from the supplied CD and that seems to have been the problem.
I let Windows re-detect the SB, but? got a "problem ... device may not work correctly.." during the detection, so I was not hopeful (this had not happened the first time I installed the device).
Nevertheless it now does work fully and is properly configured in "Total Recorder" too.
So I would suggest not using the supplied drivers and software - at least not in WinXP. But it's not very confidence inspiring.

Performance problems in games with Sound Blaster USB Sound Dev

Hello!
I recently bought a new USB sound device named "Creative Sound Blaster Surround 5. USB Sound Device"?or maybe also "Sound Blaster Li've! 24-bit External" as this is the name that Windows is displaying.
Before, i was using a C-Media PCI Audio Device.
Other system info:
Windows Vista SP
ATI Radeon 9200 LE (i know it's old, but i was able to play the games before)
2GB RAM
Now, my performance in games decreased significantly.
I only play Team Fortress 2, but i also tried an old GoldSrc engine?based game which was also slower.
The game now isn't playing fluently like before: my fps dropped and every few seconds, the graphics stop as there is a big network lag. It is now impossible to really play the game.
i already tried
- reinstalling steam and tf2
- using another usb port
- reinstalling the sound drivers
- all (both sound and graphics) settings to low
The Steam support thinks that the data transfer rate for USB isn't high enough for what is needed and recommends that i should buy an internal sound card.
But i hope there is a different solution to this problem and someone here can help.
Thanks!

No PCI interface, but USB = Slow. No hardware-acceleration (Mayber your CMedia had !real!, not pseudo?DS hardware support) so its normal that the soundblaster usb is slower in every term. But maybe sounds better...
The USB versions are only for Notebooks and other speciall situations where a PCI soundcard with X-FI or Audigy chip cannot be used...

External usb sound card is not working correctly

When my computer usb sound card is working correctly. If your computer to sleep and wake up the sound card is working correctly. If you disable the sound card and connect again, it appears extraneous sound on the background music playing. Each time the sound is different. The sound is very similar to not match the sampling frequency. If the computer is rebooted, then the sound card is working properly again.
Soundcard Infra-sonic.com model Amon.
I have not experienced problems when using the same card with Mac OS 10.5.8 with the drivers for Mac OS 10.5
Manufacturer issued driver for Snow Leopard, but the card still does not work correctly.
Also such problems, other users complain about an external USB audio card. None of the users can not find a solution to this problem.

Sound Problem Plus Memory Problem

I've also posted this same issue at the EVGA website with no help what so ever yet. Also if it's ok I'm having the above mentioned memory problem that it probable not related but if anyone does have good input I would love to hear. Hope this doesn't break any rules, didn't see anything in the listed rules thread. So here it goes.
Ok I'm having a few minor but very perplexing and annoying problems. I have recently built a new rig to include the following.
Windows 7 64 bit Home Edition
EVGA P55 FTW Intel P55 Socket LGA56
Intel Core i5-750 2.66Ghz 8M LGA56 CPU
Corsair Dominator 4GB DDR3 PC2800 (2 x 2 GB sticks)
Ultra LSP750 750w Power Supply
Seagate TB Serial ATA HD 7200/32MB
Cooler Master HAF 932 Full Tower Black Case
Galaxy GeForce GTS 250 52MB PCIe x2 (SLI Setup)
BFG - NVIDIA GeForce 9800 GT GB GDDR3 PCI Express Graphics Card (Physx Setup)
PROBLEM ONE:
This one I had a lot less that I was able to actually try because it just confused the crap out of me. So I started by going to test my sound. I'm running an optical cable from the on board sound port to back of my sony surround sound system. I get sound from my left and right channel but nothing from the center, rears or sub. So figure no biggie just need to change the configuration from 2 speaker stereo to 5. surround sound. Guess what... the option isn't there? WTF? A sound card with an optical port with no 5. support? So went online found the drivers for the sound on the mother board and tried reinstalling thinking maybe somthing was wrong with the drivers on the CD. Well it still didn't work. So I figured what ever, I got an external sound card that I know works with Windows 7 since it was on other desktop and hooked it up. Its a Creative - Sound Blaster X-Fi Surround 5. External USB Sound Card. Well it installs fine and I go to test it. Yep you guessed it! Still only sound from the left channel and the right channel with no option for surround sound. So I was able to find updated drivers for that and ran em. Well now I have an option for Surround sound with side speakers only no rear. Oh but it doesn't really matter because the left and right channel are still the only ones able to produce sound. And yes the speakers work I turned on my X-Box 360 hooked up to the same speakers and LCD tv and played COD4 with full sound working fine. So something else has to be happening I just have no idea.
PROBLEM TWO:
The second problem was with the memory. Everything booted fine but it initial only detected 2 GB. By the way I had them installed in slots and 3. So I shut down and popped em out checked the copper connectors everything looked fine and reseated the chi
ps.
This time during the boot up I checked the BIOS. It saw all 4 GBs of memory. Continued into Windows. Windows now saw all 4 but only .99 GB was available. Now the only other time I've seen anything like this was with on board video sharing the memory, and even then it wasn't half of the systems total memory. I then tried shutting down and putting the chips in 2 and 4 just see what would happen. Well I got an EA post error on the LED, couldn't even boot. So I figured o'well power down completely and tried to run the memory in 2 and 3 to run it out of dual channel. I was able to boot but still had the same issue. .99 GB available and still saw all 4. At this point it was just getting silly so I figured ok I'll download the new BIOS with my laptop, burned it to a CD. Booted the desktop and ran the BIOS flash. Update seemed work fine, honestly the BIOS didn't look much different and I didn't take note of the previous version before I did it so I can only assume it worked. However it did not fix my problem. So I'm still stuck at windows seeing 4 GB of memory with only .99 available.
Anyway... I'll keep trying to get this working and hunting around online, but I'm really hoping you all have some ideas. I'll be trying to call EVGA today for some help too and possibly Corsair. Thanks in advance for the help!

Hello,
cannot help with the sound problem.
For memory, I've got almost the same thing but with 4 sticks of 2gb and only 2 detected on an ASUS P7P55D deluxe.
Bios was my issue but I needed to do this (but with pairs of sticks instead of sticks) after the bios update to finally get my 8gb under windows:
Make a clear cmos. Then boot the computer with only one stick of ram in the port .
If everything is fine, turn off and add the other port of the same color for dual channel.
If it does not boot with the 2 sticks in the port of the good color, try to switch ports again. Maybe one stick is dead?

Sound problem in HP Pavillion dv9810us Notebook PC

Hi :
For last more than 8 months I am having this problem. First problem started with skype call. My laptop lost its speaker and showed a red X mark next to sound icon. I couldn't find any thing to fix the problem, so I did system recovery to factory setting. After that my computer downloaded windows update and security updates for vista. It upgraded my vista service pack 1 to service pack 2. In middle of this downloading stage several times I lost sound and then again got back it and again lost. I couldn't find any good solution. It is so frustrating that I can't view any videos in internet explorer which is upgraded to 9 now . I tried to watch videos in FIREFOX or Google Chrome. But no sound after few minutes watching. Every time I lost sound I tried to fix with microsft system restore or sound hardware restallation or total system recovery to factory setting. Nothing solve my problem permanantly. I contact with Microsfot vista forum, but no solutions actually fix my audio problem. At this moment my sound icon has red X mark .
This morning when I started my laptop it was ok with sound, I watched one news on Yahoo. But after that the same sound problem. In the mean time my computer downloaded vista updates automatically and installed it. When computer restarted my sound icon got red X mark. I don't understand why with some windows updates take my sound off. If I don't want to install those updates, still the sound went off when I watch videos on yahoo or Youtube. It says Yahoo is not responding, sometimes it says internet explorer is not responding. I followed all kind of solution that I got from microsft vista forum but nothing worked out. I don't know how I can fix this problem.
This question was solved.

Quick and easy fix is to buy a cheap USB sound card (it resembles a flash drive). Just do a google search and you should find one for $2 to $3.
I had the same problem where my sound disappeared and would intermittently work when I rebooted until finally it quit and rebooting wouldn't help. It seemed to have happened after a windows update AND after having errors with the QuickTouch On Screen Display. Upon research, I discovered many people had the exact same problem with this model.
I used Restore Manager to restore the drivers for the QTOSD and for the sound card and although I stopped getting errors for the QTOSD, it did not fix the sound. My quick and easy resolution to my sound problem was to purchase a USB sound card online for $2.49 at Overstock dot com. I also bought one from a local computer store, MicroCenter, that I liked better (because it had a long cord) for $10. My sound works perfect now; HOWEVER, I just realized tonight that I NO LONGER HAVE A DIAL UP MODEM EITHER. You should check to see if yours is still visible in Device Manager or in your dial up connections if you have one. I suspect the problems I had also killed my modem beyond detection because it's also a Conexant HDAUDIO Soft Data Fax Modem with SmartCP (the sound card driver is also Conexant HD). The Restore Manager won't reinstall the drivers because it doesn't see the device. It's too expensive to repair the motherboard and I don't have to have the dial up modem so for now I will just enjoy sound and my laptop for as long as it continues to live.
Again, just buy a cheap USB sound card (it looks similar to a flash drive) for a quick and easy fix. I hope this helps. Good luck. I hope you don't have other issues resulting from this as I did..

MULTIPLE USB SOUND BLASTER in ONE SYS

Hi there
I have a project that I should use 2 till 4 USB sound blaster for input data and store it .
I have bought 4 Audigy USB , for this Sound blaster Windows can not load driver for more than card and for the rest make an error and makes them disable and even when I have used MP3 sound blaster and one Audigy ,,, again no chance ...
but with a cheap sound blaster from Teratec that it used generall windows USB sound Device driver it works up two 4 parallel sound blaster atached to 4 diffrent USB port .
( really it is a GREAT SHAME FOR CRAETIVE :smileysurprised: that could not deli'ver or made it disable )
as it is very important to use 24 bit high quality sound same as Audigy , still I am looking for solution to have 4 parallel Audigy sound card in one SYSTEM ,,,,,,
ANY TIP to save my project (and my life )?

Message Edited by abifar on 0-02-2005 04:46 PM

I?m having the EXACT SAME problem. I thought it was something isolated, but apparently it isn't.
Sound just "pops" and "shutdowns" at an irregular interval of time, which is extremely annoying. I've noticed that it depends highly on the usage I'm giving the PC at the moment. When it's jsut sitting there plkaying music, it rarely happens. But if I'm browsing the web, with sites heavy on images or working on several tabs at the same time, it turns into a 0 second thing, making music almost unbareable... installing ANYTHING at the same time kills anything, 2-3 second pops and fades.
Before you even suggest it, I have a rather high end PC, phenom II 4 cored PC with 4GBs of RAM and a Caviar Black Hard dri've, so it's NOT that the PC can't handle the load. Its jsut browsing with music in the background... with half decent drivers, a 5 year old Celeron PC should be able to handle that...
I've read those troubleshooting guides over and over, and it's amazing how they suggest to shutdown/disable numerous things tha twill kill performmance in other areas, so we can have a functional audio solution. The only suggestion that makes a lot of sense is IRQ sharing with components, such as video cards/SATA dri'ves. I haven't checked/tried that, because unfortunately I'm not quite sure how/where to change the IRQ values... any help there?

[SOLVED] Audio dropouts with USB sound card

Hi! Recently I bought an external USB sound card (Music Fidelity V-DAC). If I plug in the USB cable the sound device is recognized by Phonon in KDE4 (kdemod).
If I play an audio file in Amarok (or VLC) the audio is indeed redirected to the USB sound card and played correctly. However, if I use my USB mouse, or USB keyboard dropouts are occurring in the audio signal. It seems that other USB devices are interfering with my USB sound card.
More details:
Arch Linux with kernel 2.6.33 and kdemod 4. Phonon backend is Xine. I also tried gstreamer, but this crashes Amarok/
$ cat /proc/asound/cards

I also tried an Ubuntu (9.10) live CD. Using ALSA or Pulseaudio a clean audio signal without dropouts is produced.
I wonder if someone can help me with this problem, or point me to more information. Thanks!

Thanks for your suggestion. I added the following line to my /etc/modprobe.d/modprobe.conf file:
options snd-usb-audio enable_msi=1
After a reboot the problem still persists. I also tried another suggestion from this forum:
options snd-usb-audio nrpacks=1
This doesn't work either. I tried to change settings in /etc/security/limits.conf, which looks like this:
@audio - rtprio 99
@audio - nice -10
@audio - memlock 250000

USB sound card crackling when changing nr of channels in ALSA

Hello! I have read the alsa config and some related posts from brebs (https://bbs.archlinux.org/profile.php?id=10353) and I setup upmixing to 5.1 and dmix with a USB sound card. It works, but the sound is constantly crackling. I have simplified my .asoundrc to find out where did this problem came from and I got this:
pcm.!default {
type plug
slave.pcm "dmix6"
pcm.dmix6 {
type asym
playback.pcm {
type dmix
ipc_key 567829
slave {
pcm "hw:0,0"
channels 6
It strill crackles with this config but when I change the channels to 2 there is no crackling anymore. I messed with buffer_size and period_size but the problem persists. Using surround51 does not fix it either. Thank you!
Edit: Forgot to mention my sound card, it's a Sweex SC016.

USB Sound Card by default

Hi All,
Since i've upgraded to snow leopard i've been having an issue with my USB Sound Card. It's a Behringer U-Control UCA-202 that's connected via a Belkin 4 port hub through my Dell 2407WFP monitor to my MBP. Everytime i restart Snow Leopard automatically defaults to the Built-In Soundcard instead of my USB Sound Card by default. It's not a major issue but it's annoying having to go into the sound preference or Audio MIDI to select it. I never had this issue on Leopard and i've tried connecting the USB sound card directly to the MBP but the same thing happens on restart.
Many Thanks,
MuraliM

I'm now on 10.6.1 and I still have the same problem. I select "USB Sound Codec" in Sound preferences and when i restart (with everything still connected) my Mac still reverts to the built-in sound card in my MBP. In Leopard (and even Tiger) my Mac would select the last selected sound card by default on restart and if my USB sound card wasn't connected (i.e when I'm on the move) the Built-In Sound Card would be selected. Is there something I'm doing wrong or is it what I think it is, a problem with Snow Leopard and if it is how can I make Apple aware of this problem? Now that my printer and with this soundcard problem i'm considering just reformatting and restoring my Leopard install.
Many thanks,
Murali

[SOLVED] USB sound broblem.

Greetings everyone. Kinda sucks making my first post on new boards this way.
Can't say I am very experienced linux-wise, but until now I successfully overcame all problems I've encountered. On this one I can't even think where to start, because all this kernel stuff is kinda complicated to me yet.
After initial install all hardware were detected and working well. During days of polishing system I lost track of changes and can't really say what triggered my USB sound card disappearance. At first I was blaming ALSA, but then I checked kernel.log:

As you can see: there is no usb 6-1 "After". Let ALSA messing alone (because it seems unrelated) so far I tried:
- different USB ports
- reinstalling kernel
Any tips or solutions are welcome.

After reinstalling udev, I atleast started to getting following things:
Oct 15 18:22:36 localhost kernel: usb 7-1: new full speed USB device using uhci_hcd and address 2

Oct 15 18:22:36 localhost kernel: usb 7-1: device descriptor read/64, error -71
I tried echo -1 >/sys/module/usbcore/parameters/autosuspend as somewhere suggested, but didn't help a bit.
There is also solution to disable USB 2.0 via modprobe -r ehci_hcd, but I cannot allow that because through this device I stream much bigger bandwidth, than USB1.0/1.1 can handle.
EDIT:
- tried to remove and modify /etc/modprobe.d/usb-load-ehci-first.conf to ohci load first
- tried to add "irqpoll" as kernel option
- echo Y > /sys/module/usbcore/parameters/old_scheme_first
No luck.
EDIT2:
Alright people. The device is gone for good. Other computers cannot see it as well, neither Windows 7 on media center or Ubuntu on laptop. Dunno if Arch fried it somehow ^_^

USB Sound Card won't Show in Sys. Pref. Sound Pane

Hi, This has problem has happened occurred recently. I bought a USB Sound Card and it was working fine. I also have a USB Microphone that was working fine. (I am a DJ) I have a USB MIDI Turntable also, it works. One thing I could not get to work at all; MIDI I/O to USB adapter.
Everything has been working, except the MIDI I/O to USB adapter. All of a sudden everything stopped working except my turntable. It all shows up in System Profiler, but not in the Sound Preference Pane in System Preferences. I don't know why they stop working all of a sudden.
Plus one thing that I have had problems with. MIDI I/O to USB adapter does not work with any program. I bought it, it is plug and play, and it shows up in System Profiler. But it won't show up in the Audio Midi Setup.
Any Suggestions?

UPDATE: I got the MIDI I/O to USB adapter working. Now I just need to get the USB Microphone and USB Sound Card to work.
