[SOLVED] moc: "FATAL_ERROR: No valid sound driver! Server exited!"

mocp
Running the server...
Trying JACK...
Trying ALSA...
ALSA lib pcm_hw.c:1741:(_snd_pcm_hw_open) Unknown field mmap_emulation
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Trying OSS...
FATAL_ERROR: No valid sound driver!
FATAL_ERROR: Server exited!
so some time ago i messed up the sound badly and now i'm clueless on what to do. i have alsa, oss and pulseaudio (re-re-re-re-re)installed (i know i shouldn't). i'm a total noob when it comes to the audio department so i can't really add way too much to it.
audacious drops the following when i try to play something:
ALSA error: snd_pcm_open failed: Invalid argument.
there is audio, however (some games/web) if i pulseaudio --start.
pls ask for outputs to give you the necessary info

did you have working audio before you did something that messed it up?
alsa is pretty much all you need for working audio. You could run pulseaudio on top of it if you want, but usually it doesn't benefit you in any way unless you have some specific issues with alsa, like audio only playing from one application at the time.
You can safely remove everything OSS related, unless you actually want to configure your system to use OSS for some reason.
If you want to revert to default your alsa configuration you could just remove your ~/.asoundrc and /etc/asound.conf if you have modified those files. If you want to use pulseaudio, reinstall pulseaudio-alsa to revert /etc/asound.conf configuration so that your alsa-only applications work with pulse.

Qosmio F30 Sound Driver for Windows Server 2008

I am running a virtual machine with Windows Server 2008 installed on it. The server sees my Sound Driver but it doesn't recognize it and asks for driver all the time. I tried running the Sound Driver installer from the CD but it did work, said: Unsupported operating system. I searched all the web for a driver and I didn't find any. Can any one help in finding this driver for me or let me know it it is possible to manually install this driver?
I'll be so thankfull for any help.

As you probably know Qosmio F30 is not designed to be used as a server and generally speaking Toshiba doesnt support Server2008. All you can do is to identify sound card manufacturer and try to find the driver on their support page.
Sorry buddy but thats all what I can say about it.

Satellite A300D-15B PSAKCE - Cannot install the Win XP 64bit sound driver

Hello all,
This is my first post here after lurking for the last week or two, My hope is that somewhere here there is help and hence hope!
I have a wonderful Toshiba A300D-15B PSAKCE with 4GB/O RAM, however I am suffering from some problems that the holy SEARCH function cannot solve. I use this laptop as a development box for uni/work alas...
After an absolute nightmare with Vista32 and Vista64 I decided to go back to windows XP32, however this wont install, keeps claiming a CRC file failure after (and yes this is with the SATA in IDE mode and with an XPSP2 disk)
I decided that I really DONT want to goback to Vista, so installed Windows XP64. Now the initial Instal goes very easy, I have the basic setup, the chipset, graphics, network, processor, usb, pretty much the basic... except... and this is where I have lost most of my hair.... SOUND!
Firstly attempting to install the sound driver results in Failure, claiming the mmdriver.inf cannot be found or corrupt, obviously I checked, and yes there it is, for the sake of it downloaded the MMDRIVER.INF and placed it system32, and still the install fails.
I have also tried a "Manual Install", from the .inf files... this includes the XP32/64 drivers and the Vista 32/64 bit drivers, still the same
problem, driver continues to fail install. I am becoming increasingly bald. Outstanding Drivers that WONT install
*-Audio Device on High Defninition Audio Bus*
*-Mass Storage Controller*
*-Modem Device on High Defninition Audio Bus*
*-USB Device*
If the following is any help, (Sandra 2008)
*-Disk Controller*
(AMD(ATI) SB700 SATA Controller [IDE Mode])
*-Disk Controller*
(Toshiba SB700 IDE)
*-Audio Device*
(Toshiba IXP High Definition Audio Controller)
*-Audio Codec*
(Conexant Systems 5051h)
*-Audio Device*
(AMD (ATI) RV635 Audio device [Radeon HD 3600 Series]
Now, as I write this I have heard rumor that the A305D uses the same
audio/graphics drivers.... well.... off to try something I guess...
if there is any help or ideas I would appreciate it.

Thanks Jaba
Initially I attempted to locate the MS patches you mentioned, KB835221 and KB888111 respectively, alas there were none available that I could find for XP64, also at the time of tapping this message theres no XPSP3 for XP64 bit either.
Lucky for me I logged into my MSDN account and downloaded XP+XPSP3 tore the house up looking for a CDR... anyway long story short.... solved all the problems with the required updates of SP3, I now have my Toshiba A300D-15B all singing 'n dancing laptop setup completely with XP32.
Had to take a hit on the RAM though, gonnna have to go on with only 3.2GB instead of 4GB,
arguably when one counts the memory foot-print that vista ultimate 64 had used I am probalby still on a winner here in memory avaiable terms LOL!
thanks again! much help!

DVD Player installation error A valid DVD drive could not be found. [-70012]

My iMac has an external "superdrive" and I can't play files .dvdmedia. On opening the DVD Player I get this message: There was installation error A valid DVD drive could not be found. [-70012]
This sent an error message to Apple when I click the OK button.
I have tried to relinstall the DVD player.app from the SnowLeopard disc, but this app was not on the list for custom install. I have repaired permissions, no help! I have shut down and waited several minutes and restarted, no help.

My continued frustration with this problem lead me to an archived discussion https://discussions.apple.com/thread/2020977?start=0&tstart=0 This lead me to beleive I need to use the reset password to fully repair my permissions as contained there. Also while booted in the install disc, I performed a Repair Disc on the StartUp disc.
After all this, when I restarted, the DVD Player was able to play DVDmedia files completely.
So I quess I solved my own problem.

Satellite P200-1B6: Sound Driver update fails and HD-DVD Player doesn't work

I have just bought a Satellite P200-1B6 laptop and spent the day installing the updates recommended by the TEMPO program. One of these was a Sound Driver update from RealTek but on running this it fails about 80% of the way through with an error: 'Install Realtek HD Audio Driver Failure !!'.
Now the Toshiba HD DVD player fails to start with an error 'Unable to output the video to an external device.
Please switch your display device by pressing the Fn + F5 keys after ending the application'. I've tried this but it seems to have no effect.
I'm now regretting starting to update the installed drivers. Should I try to rebuild the machine using the recovery discs or is there another solution that someone has found? Or have others found the upgrade works?
Any advice welcome

Last month I upgraded my PC Satellite P200 (BIOS, Driver ATI HD2600, Package VAP and HD-DVD Player).
But after this update, I was no longer be able to read my HD-DVDs
Error message was: "Unable to send the video to an external device. Please turn off the display device."
The problem was much of the update Realtek R1.76 (Realtek Sound Driver - 6.0.1.547 - 20/11/07) currently proposed on the site toshiba.
Indeed, the P200-1DE is equipped with Realtek ALC268 Audio Codec.
The latest update of this codec is R1.89. I downloaded from the site Realtek and it has allowed me to solve the problem.
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level= 4&Conn=3&DownTypeID=3&GetDown=false]
I have no problem since that last update

T530 Dolby Sound Driver doesn't start

Hi
Everytime I start Windows on my T530 I get an error message from Dolby Advanced Audio that the Dolby sound driver can't be startet and that I have to restart the computer or reinstall the driver.
I reinstalled and restarted several times but it still doesn't work.
Before this problem I had another error message that the hardware and the driver didn't correspond so I downloaded the driver for the T530 from Leonvos homepage. But the new driver doesn't start.
What do I do?
Regards, Rasmus

I tried to reinstall the old driver that came with the system but now I get the error message (same as before I updated to the new driver):
The existing Dolby audio driver version is 7.2.8000.17 and the software application expects the driver version 7.2.7000.7. Install a valid combination of driver and software application.
I'd be thankfull if someone can help me out here.
Kind regards

Notebook dv8285ea with Windows 7: Sound driver not working

On my Notebook dv8285ea (bought in 2006), that came with Windows XP, I have mounted a new SSD drive and installed Windows 7 Prof (32 bit). - It works fine except for one problem: There is no sound from the speakers. I get error messages such as "No Audio Output Device installed". That is: The Sound part of the motherboard is not compatible with the Windows 7 sound driver.
Can anyone point to a solution? - The dv8285 is not among the notebooks that HP has provided Win7 drivers for.
