General :: Sound Lacking High And Low End
Jul 1, 2010
Is this just a standard characteristic of Linux or is there some way I can EQ all the audio? I've had nothing but problems with audio sounding like a scratched record in Linux. It would skip, crackle and break up no matter the source or volume. Found a solution that one to simply remove PulseAudio.
I'm using Altec Lansing ADA885 speakers with 8" DVC subwoofer. System response is good down to ~28Hz but it sounds like a cheap boombox. Last time I had these hooked up to a Windows (XP Pro) system, the bass was deep and full. Very audible all the way down. Now it sounds like the audio is boosted at center frequencies and overly cut on high and low end.I even tried putting in a PCI Turtle Beach Santa Cruz 5.1 card and the sound did NOT improve.

My laptop is a Dell Inspiron 510m with onboard Intel 855 sound (STAC 9750 AC97). The sound was perfect with WinXP, but with Ubuntu it's tinny and lacks richness and vibrates and distorts at higher volumes. I've played around with Alsamixer and changed the driver from ALSA to OSS4 and it has improved slightly, but still not perfect. Is it just not gonna get any better, should I not be expecting it to be as good as WinXP?
I've seen on the Intel site a Linux driver for my controller, it's a tarball but it won't compile after extracting it (read on this forum that someone had the exact same problem with that driver). Will the Intel driver not help, does the problem go deeper than just the driver? It would be perfect it you could just wrap the Dell/Intel driver and use that (just like with wireless ndiswrapper).

Motherboard: Asus P5KPL-CM
Audio Chipset: VIA VT1708B
No linux sound drivers on Asus' site. No ubuntu 9.10 drivers on VIA site. Low sound with default drivers. I've edited /etc/modprobe.d/alsa-base.conf with options snd-hda-intel model=3stack, but no luck. I actually had to do a sudo sh then edit it that way with vi because it was read only. Didn't do anything.

I am using a Dell Inspiron Laptop 1464. I have Ubuntu 11.04 Installed, and every time I have the volume at MAX and especially when I'm listening to music that has like high bit-rate (342) or what ever, there is a glitch in the sound, it sounds like when a CD skips or when it is scratched. I tried installing all types of different mp3 encoders and still the same.
Also it is the same when I use Banshee or Rhythumbox.

I usually run the default gnome session but also installed kde and enjoy popping over every now and then.
Now, after the lucid upgrade, things are not happy. There is just a black screen after the login.
My cairo dock comes up, but no other panels.
The only other thing I see is TokBox.
Not a pretty sight at all.

Several days ago, I replace my PC's motherboard and now sound is too low - I can't hear practically anything, I used alsamixer to configure output volume level to normal, but this won't survive reboot.
I tried to use 'alsactl' and saveed rules, and edited rc.local to restore - but it didn't help. Can anyone tell me how to fix it?

I am getting a high pitched ringing sound coming from my speakers and headphones on 9.10.Does anyone have any ideas what is causing this problem and how to fix it? It is really annoying after awhile and is headache inducing.I've tried switching from PulseAudio and ALSA with no changes.

It always fails when I try the sound card test. It says like the system cant detect the sound card.
Sound Card: 5 series / 3400 series chipset high definition audio
Module: snd-hda-intel
After searching about the issue, I found the information that installing kmod-alsa-PAE-1.0.20-1.el5.elrepo.i686.rpm and kmod-alsa-1.0.20-1.el5.elrepo.i686 would solve the problem.
But even I downloaded and installed them, nothing changed.

i've recently installed pidgin via the Ubuntu Software Center. Unfortunnately it is lacking a "chat history" just like for example "Trillian" on Windows. Is there any IM-prog on Ubuntu which saves all conversations with any contact into files? (Just like Trillian on windows)

I am using centos 5, Kernel 2.6.18-53.el5. I am using 2 quad core processor with 4gb of ram
I am trying to figure out the significance of %CPU in the ps command.
My astreisk process %CPU is very high at the moment, at 115. I want to know if it is a cause for concern? If I do a top then the load of the box is very low.
Code:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 2872 115 1.4 628664 58372 ? Sl 14:56 190:30 /usr/sbin/asterisk -f -vvvg -c

I have a server running samba process and there are about 70 samba users connected at a time. The system has 4Gb of memory and it seems each samba process is utilizing only 3352Kb of memory.
When I run the command
pmap -d (pid of samba)
It gives as:
b7ffa000 4 rw-s- 0000000000000000 0fd:00003 messages.tdb
bfe46000 1768 rw--- 00000000bfe46000 000:00000 [ stack ]
ffffe000 4 r-x-- 0000000000000000 000:00000 [ anon ]
mapped: 33384K writeable/private: 3352K shared: 20504K
But when I run the top command, it results as below:
Tasks: 163 total, 1 running, 162 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.9% us, 4.9% sy, 0.0% ni, 93.3% id, 0.8% wa, 0.2% hi, 0.0% si
Mem: 3895444k total, 3163192k used, 732252k free, 352344k buffers
Swap: 2097144k total, 208k used, 2096936k free, 2487636k cached
Why could the system be utilizing such high memory? By the way, the server is not running other processes. The samba version running in it is 3.0.33-0.17.

I just built my first computer from the ground up and installed linux x86_64, FC10, and among other problems, i cannot get the volume of my speakers to play much above a low volume. i have the pulseaudio volume control set to 100% for the output and input levels. i adjust all my video and audio players volumes to the max also, but the volume from the speakers is still very low. the speakers worked fine with my old hp computer. is there anything i can do, adjust to fix this?

During downloads, the top command shows the Firefox process at 100% CPU. Yesterday I tried to download an .iso image. After a few hours the Firefox window would not refresh nor would it respond to input. I tried the wget command. It used negligible CPU time and completed in 28 minutes.
This problem is easy to reproduce because it happens every time I download a file in Firefox. It also happens when I use a fresh profile to run Firefox without any extensions or plugins.
This is Firefox 3.6.12 on Fedora 14.

I have High load on my server and my investigation shows nothing (so i believe that my investigations is wrong ), the load average in this moment is 10.13, 9.47, 8.24. , mentioning the below.
- The disk utilization (all the disks) is near 0, as the result of the IOSTAT
- There is no blocked processes (as a result of VMSTAT).
- I have two processors (dual core) , the maximum load average should be something around 4.
- The server always have above 8 load average in all times interval.
btw , my OS is RHEL AS release 4 (Nahant Update 7)Kernel :Linux 2.6.9-78.ELhugemem #1 SMP i686 i686 i386 GNU/Linux

I've been having a problem in Ubuntu 9.10 recently where starting about 2 minutes after startup my computer slows down and becomes unresponsive. I believe the problem is associated with a high IOWait because I have the system monitor applet on my Gnome Panel and it displays 100% IOWait every time my system starts to slow down. I have tried booting into other kernel version and the problem persists. I don't really know what IOWait is or how to diagnose this problem further. I've looked around online and it seems like you have to find a specific process that is causing the IOWait, but I don't understand how to go about doing that.

Just trying to figure out some stuff with a broken process. A java app seems to sometime get stuck on a loop or something and i'm trying to find out what's causing it using just the following #sysadmin tools at my disposal.
Things like:- htop - find the PID thats causing the High CPU cycles. I'd then want to use /proc/[PID] or lsof -p [PID] or strace [PID] etc. But the PID doesn't exist in 'ps -ef' output so I think htop must be showing me kernel level thread PIDs?
Not sure about the PID's HTOP is actually giving me? I know that some of them are the real PID's that can be accessed through /proc/[pid] etc but others are not but are i assume child processes or more likely threads as child processes are normally shown in a default ps output anyway.
Is someone able to help distinguish to me about what exactly all these other PID's are that I can't manipulate or find apart from when using HTOP.

I want to use 1920x1080 in the virtual consoles, with:
Debian Squeeze; proprierary ATI drivers.
Switching back to the open source drivers, it works automatically, but I got no clue with these ones. Someone say I should use uvesafb by modifing initramfs accordingly.

We have a 32bit Gui application created using C++. We ported the application from Solaris to Linux. Issue we are facing is the size of the library and executable is very large in LINUX compared to Solaris. Red Hat Enterprise Linux 5.4 is the Linux version we using. Please find a sample dynamic library created. We would like to know the following behavior of LINUX is normal or not. Consider we created two files test1.cc and test2.cc. Both having a single line of code.

I'm not all that familiar with what it is that the expensive SATA cards do, other than providing on-board cache and many ports, but all things considered what can't a CPU and lot's-o-RAM do that an expensive SATA card can?This assumes, of course, that you weren't planning on using the CPU to run other applications (i.e. a SAN type setup).

After changing servers and moving things around, I have one system which serves the /home directories, and for some reason, it is extremely slow. I've looked for duplicate IPs, signs of a HW problem, etc. and cannot figure out why the system is running with a high load, high iowaits, and low responsiveness. The servers and clients are slackware 12.2 and 13.1 respectively.

I'm sick of screwing around trying to script a clean solution to burn multiple files and folders to CDs and DVDs with wodim, growisofs and genisoimage.I'm looking for a high level command line program that uses sensible defaults and takes arguments something like this:[program-name] [cd|dvd] /path/to/dir1/ /path/to/dir2/ /path/to/file ...It should then do all the low level copying and ISO generation transparently and just burn the damn disk!Does anyone have any suggestions? I've looked at several programs but it seems there are too many choices to trawl through and not enough information about them online.

What should look like X Window System (X.Org) modeline to be put in xorg.conf, for high resolution (incuding recommended 1680x1050 @ 50Hz resolution) for 22" NEC LCD 22WV monitor? X.Org autodetect correctly only 800x600 and lower resolution SVGA modes,unfortunately.1,2
How can I generate proper "Modeline" line for xorg.conf? Is information included in NEC_Datasheet_LCD22WV-english.pdf enough (found on NEC LCD 22WV product info page)? What tools there are available to generate proper modeline for a LCD monitor for Linux? MS Windows (MS Windows XP Home) correctly detects and use 1680x1050 resolution; can I somehow get modeline information from MS Windows?
Footnotes:
1) It might be hardware problem with the monitor itself, as the same LiveCD Linux distribution that couldn't autodetect recommended 1680x1050 mode for NEC LCD 22WV monitor, correctly autodetects recommended 1440x900 mode for slightly smaller NEC LCD 19WV monitor from the same family, by the same producent.
2) Or it might be problem with graphics card (NVIDIA Riva TNT2 M64) not supporting such resolution, or with graphics driver not supporting such resolution.
