L702x: subwoofer not working

I own a Dell L702x and I realized that the subwoofer is not working. As I saw, many users of similar laptops (that contain the ALC665) have the same problem. The subwoofer is not detected by alsa.
Has anybody encountered the same problem and fixed it? I tried in some different ways, but nothing happens.
Edit: Here is the alsa-info output: http://pastebin.com/DFBv7uvE.

My subwoofer did not work initially, though I have a very different setup. The solution was to play with the model used by the snd_hda_intel module. From this, this, and this, you might want to try putting the following in /etc/modproble.d/sound.conf:
options snd-hda-intel model=asus-mode[x]
where [x] is a number 1-8.

X-Fi Audio - Subwoofer NOT working in Vista 32-bit Ultimate!

<X-Fi Audio - Subwoofer NOT working in Vista 32-bit Ultimate!I I have WIndows Vista 32-bit Ultimate and Sound Blaster X-Fi Audio installed and with the factory drivers (I tried another set earlier and they did not work, so I reinstalled the original drivers which worked, at least partially). Until now I only listened to music using my headphones, but I tried today to plug-in my 5. Genius system (50W RMS) and everything works fine EXCEPT the subwoofer does not produce any sound at all!! The ONLY way to make it work is go to Control Panel -> Sound -> Speakers -> press Configure and then click the Test button in the dialog that appears (or click the subwoofer icon to make it produce a very nice bass sound - which I absolutely love, but it's the only way to make my subwoofer work!!!). Please guys, help me find out what the problem is. All help is much appreciated. Thank you!

Thank you my friend,I have done as you have mentioned (made sure the DLL did not stay there when I rebooted before I installed your version), and now I have the version which you have built. However, I am still unable to hear the subwoofer I am so sad... even my default on-board card supports the 5. just great, and I love the sound of that, but I was hoping for something better from Creative - instead, all I got was a soundcard I can only use with my headphones at the moment because of a faulty driver...
Did you enable Bass Redirection?
Run Console Launcher, click on Speakers and Headphone -> choose 5. Speakers.
Then click on Bass (Bass Management) and enable Bass Redirection.

External subwoofer not working with Satellite C55t-A5222

When I plug in an external speaker system into my laptop, the speakers work, but the subwoofer does not. I have tried two different speaker systems and have the same problem. I know the subwoofer works, because when I connect an ipod or iphone to the speakers through bluetooth, the sound is great. How can I get the same sound when the speakers are connected directly to my Satellite C55t-A5222 laptop? I have verified that I have the latest driver for my sound.

I was having the same problem, so I called Customer Service. The Tech diagnosed the problem with the Realtek HD Audio Manager. I had upgraded to Windows 8.1 from 8.0 so some of the drivers and devices my not have installed correctly, he guessed.
He went Control Panel > Hardware and Sound
Under Devices and Printers he selected Device Manager>Sound, video and game conroller>
He seleced Realtek High Definition Audio
He went to the Driver Tab and selected 'Uninstall"
He uninstalled the Realtek Device and rebooted my laptop.
After the Reboot, he went back to Control Panel>Hardware and Sound and went all the way at the bottom selected "Realtek HD Audio Manager. I don't recall if it was there before, but I assumed it wasn't since he was not able to find it previously.
The then opened up the Realtek HD Audio Manager and selected DTS Tab and clicked the 'Launch' Button. He then selected 'External Speakers and 'Viola' My External Cyber Acoustics CA-3602 2.1 Speakers including the Sub Woofer were 'shaking' my office again! YEAH!!
He said that each time I want to use the External Speakers and Headset I might have to select it in the Realteck HD Audio Manager if it is not working! THANKS "SAM" (my Toshiba Tech Guy's psuedonym)
Hope this helps you guys

External subwoofer not working on Asus n55sf notebook

The external subwoofer that comes with the notebook -- which has a proprietary audio jack connection -- doesn't seem to work.
While based on a web search I'm not certain anyone has got the subwoofer working reliably, the following Ubuntu bug thread suggests there is at least one other Arch user who has got the subwoofer working for a while (at least until the upgrade to Kernel 3.1).
https://bugs.launchpad.net/ubuntu/+sour … bug/871808
Does anyone have any ideas how I can get it working? I've tried all the possible solutions suggested in the bug. The hda_analyzer codec tweaks don't work for me. My system is up to date. I'm running Gnome 3, alsa and pulseaudio.
The output of my alsa-info.sh is http://www.alsa-project.org/db/?f=4777d … af41b8d3bb
Perhaps I need to file a bug with the alsa project?
Thanks in advance for any suggestions.

A further update:
My sound chip is a Realtek ALC663. I've tried to setting the model version in /etc/modprobe.d/alsa.conf using the following statement
options snd-hda-intel model=3stack-6ch-dig
Models are specified for the ALC663 chip at http://www.mjmwired.net/kernel/Document … Models.txt. I have tried the following models:
3stack-dig    3-stack (2-channel) with SPDIF
3stack-6ch    3-stack (6-channel)
3stack-6ch-dig 3-stack (6-channel) with SPDIF
5stack-dig    5-stack with SPDIF
g50v    ASUS G50V
asus-mode1 ASUS
asus-mode2 ASUS
asus-mode8 ASUS
dell-zm1    Dell ZM1 with ALC272
auto    auto-config reading BIOS (default)
I can get the subwoofer working under some of these configurations but that typically means selecting surround sound and having missing channels (I think the laptop has a left front and a right front channel and the external subwoofer, not a front centre or any rear speakers). Typically, the subwoofer, when working is linked to the right channel, so it would appear that the right channel is output through the subwoofer and the left channel through the front speakers.
I think I need to file a bug with ALSA project and hope that support for my laptop can be included in a future release of ALSA.

2 of 4 speakers and Subwoofer not working for Altec Lansing Lucasfilms THX Surround (circa 2003)

I am attempting to connect my Altec Lansing Lucasfilm THX 5.1 sound system to my HP ENVY All-in-one. I think the original audio card for the sound system came on a Dell with Soundblaster.
I have connected the green audio to the jack in the back which only gets 2 of the 4 speakers working (even after configuring the speakers). The subwoofer is connected to the sub jack in the back panel as well and is not working at all. I realize that I am trying to have an ancient sound system work with my fancy new HP Envy. Am I asking too much?? I thought maybe a driver update might be needed. But in theory, if those jacks are available in the back it should work (she says optimistically).
Any suggestions or advice would be appreciated.

Not a problem. Thank you for the additional information.
It sounds like you have the speakers connected correctly. If there is only one connector for all of the speakers, it may be that you will only be able to use two of them. However, I am not certain why the subwoofer isn't working. Is it selected in the Control Panel / Sound? I realize that you said the speakers are configured in the Control Panel, but is the subwoofer separate?
I have an old (2001) Polk Audio set of speakers. I have only been able to get two of them and the subwoofer to work with my new HP computer. It sounds fine without the other two speakers.

Subwoofer not working with THX cons

Ok here's my problems,
When I updated for the last drivers, my subwoofer stopped working when I calibrate my speaker. When I don't use this options, I can have a good sound. but when I turned in on I loose all my base. So when I play games, I don't have any loud sound on. It's becomming anoying. I've tried to uninstall and install it for 6 times, and have error from plvcore.plx or something like that, and got throught it. But now event if I uninstall physically the card. there's no way out I don't have any loudness when Calibrate the speaker.
I ran a speaker test from the speaker options and it worked (I didn't use my computer that test)
when I use my computer as soon as I have my calibrate settings I don't have my subwoofer working.
It's not the EAX redirection 'cause I used it and didn't notice a change when I jplay Games (CS) only when I listen to music.
I have a Audigy 2 zs Platinum with a Z-5500 from logitech

I need help.. anyone got an Idea?

Subwoofer not working with Audigy

Unlike most posters to this forum, I have only a 2. speaker setup connected to my 2ZS. I recently upgraded to Vista Ultimate (32-bit). The beta drivers for my sound card are working ok, in that I can get sound (with reasonable quality), but I'm not sure if the subwoofer is working. The Vista control panel only offers 2.0, not 2. sound. Is there anything special I need to do to make the subwoofer work?

Subwoofer not working

Just received my HP p-030nr beats laptop. Says it has a built in subwoofer. There is no bass at all from this laptop. Headphone jack sounds ok. Found a driver update on HP's site for this. It uninstalls the old driver and installs the new one. Tried this. Both my old netbooks and my wifes 8 yr old Dell blow this laptop away in the speaker dept. Any ideas? This thing at full volume is quieter than my phone.

Subwoofer not working after HDD have been replaced with SDD

Greetings,
Today I was helping a friend to replace his HDD with the new SDD he bought for his mid 2012 Macbook pro 15. We also got a caddy to replace DVD with old HDD, thus leaving him with two discs (I have already done this couple of times on different macs). After we finished, everything was working fine, both discs running smooth etc. However, after playing a song from iTunes, we noticed that there is no bass whatsoever in the playback. We both are audio engineers and know frequencies pretty good, so everything below 200 Khz cannot be heard. We tested the built-in output with the headphones we are familiar with, and it is working normally. Then we made A/B test with Macbook pro 13 and this particular 15 I am talking about - low freq. are apparently way more transparent comparing to 15, which is insane. So, we checked the positioning of the speakers on the board and figured out that there is a woofer just next to the HDD slot. However, we were careful and did not pull anything or made any physical impact that would kill the woofer.... any ideas or similar experiences? Thank you in advance, he needs his mac ASAP, it is our bread and butter

Sticky This : Surround Sound coming out of front speakers and Subwoofer not work

The problem with Creative forum moderators and the like is that they have used their products so often that they forget the basic really simplistic things and as a result have a lot of frustrated customers (As indicated by the number of?problem posts?when this really need not be the case)?After building myself a media center with Windows XP (Yes the best DVD backup software is made for XP) my?X-Fi card Surround, Centre and Front Speakers were all mapped together for sound. After searching through the forums at many unanswered posts with similar problems I eventually came across the answer a few months back after a few days of reading this forums posts. The problem arises because of the Windows default settings which need to be changed when insatalling the sound card. Which I believe a good driver should be doing anyway. This is the menu path:StartControl PanelSounds and Audio DevicesAudioAdvancedPerformanceHardware Acceleration slide indicator should be on Full, then Apply?At this stage I got all the Speakers to work independently except the Subwoofer?I am not one to sit and study a user manual comprehensi'vely before attempting installation. I normally look for any serious warnings or precautions adhere to them and then slap the thing in and usually everything just happens in the correct sequence or that is how it should be with a new piece of hardware anyway. I use the manual more for problem solving. Anyways my point is that I have not read the manual in depth yet but all must be aware that you need?4-part jacks to get the most out of your?X-Fi sound card. The extra?points are required?in the Center/Subwoofer and Rear Speaker jacks because the extra connections within these jacks are used for SPDIF out on the Center/Subwoofer Jack and Side speakers for your 7. system on the rear speaker jack. (I dunno why they don't just put in 2 extra jacks that are the normal 3-part jacks .....or perhaps it's a way to force you to buy creative speakers which come with very rare?4-part jacks)?The subwoofwer can only be made to work if you pull out the 3-part jack just enough to make the correct contact with the card that gives you subwoofer signal.

@tryignan ,
Hello and thank you for posting on the HP support forum. I have one question have you tried doing a system restore back to before this problem started. Something has updated or changed in the drivers or Operating system to cause this.
Have you removed both audio drivers and just ran with the AMD audio driver.
Now did you try this when you removed your drivers. Try booting into safemode and remove the two audio drivers.
Download your software and drivers for your system and save to dvd or usb memory stick.
Run the Recovery manager to restore software and drivers to factory spec.
Using Recovery Manager to Restore Software and Drivers (Windows 8)
Now if that fails try doing the full Windows 8 recovery.
Performing an HP system recovery (Windows 8)
Please post back and let me know if this was of any help.
Thank you again for posting and have a great day and a happy new year.

Subwoofer not working prope

Hello.
I recently purchased an Audigy Value soundcard and I'm using Altec Lansing's 5i 5. speakers.All the speakers work fine except for the subwoofer. The bass produced is very weak even though the subwoofer volume is maxed out. Is there any settings that I can tweak to make the subwoofer work properly?Thanks.

Are you playing stereo or DVD surround sound? If stereo, then are you talking about the subwoofer volume control in the Surround Mixer, Advanced tab (with CMSS 3D selected in EAX)? Or the subwoofer volume in Speaker Settings, Bass Management? There might also be a Bass Boost tab. Not sure if the Audigy Value has these options, or you may have all this setup already, so this may not help.

Hp pavilion dv7-4152si subwoofer not working after updating bios

hi there,
i have recently updated my bios and since then i do not have any sound coming from my subwoofer.
when i go into my bass management settings, it tells me that my subwoofer is not present.
i tried to update the driver, but after that i could hear no sound whatsoever, so i rolled back the drivers.
any help would be appreciated, thanks!

Hi
I'm experiencing the same issue with my dv7-4152si. Have you find a way to resolve this issue?
I had a look in my beats but can't find a subwoofer setting at all.
Kind regards

Center and Subwoofer not work

HI, I'm new to the forums. I installed Vista last week and I noticed that suddenly my Center and Subwoofer output is non existant... is this secondary to the drivers or maybe problems with the speakers? (in other words, is this a known problem with the beta drivers for Audigy 2 or should I investigate the possibility of problems with my speakers)

NFS,
Do this (if a step fails, note it and move to the next):
1) Unplug all the connections between the sound card and the speakers.
2) Plug an 1/8'' patch cable into the rear speaker out on the sound card.
3) Go into speaker settings on the computer and set it to 5.1
4) Plug the other end of the 1/8'' patch cable into the rear speaker input on the speakers and run a test. Rear left and right should come out of the rear speakers
5) Move the plug on the speakers to the front speaker input (keeping it plugged into the rear out on the sound card) run a test. Rear left and right should come out of the front speakers.
6) Move the plug on the speakers to the center/sub input. Run the test. Rear left and right should come out of the center and be muffled in the sub (it may not play out of the Sub at all)
7) Move the plug on the speakers to the rear input.
8) Move the plug on the sound card to the Front Speaker out. Run a test. Front left/right should come out of the rear speakers.
9) Move the plug on the sound card to the Center/subwoofer out. Run a test. You should hear only the center channel out of one of the rear speakers.
Post back with the results and where it failed.
