ALSA - mic trouble

by Eric Stein

Hi, When I first set up my Ubuntu machine, everything worked fine. But for the last few months (I don't remember exactly how long), my mic has refused to work. Nothing I use can pick up any signal from it. I've tried all the mixers (alsamixer, kmix, the built in GNOME mixer), and none of them show the mic as muted. Is there a way to reset ALSA's volumes and other mixer settings to defaults? I can't seem to find information about this online, and this lack of a fully working sound system has me on the end of my rope. Info: Ubuntu Breezy 5.10 Linux pippin 2.6.12-10-386 #1 Tue Jul 18 22:08:27 UTC 2006 i686 GNU/Linux I'm prepared to spend a good deal of time on this, but I don't know what I need to do. If you need more information, let me know how to get it and I'll be happy to share it. Eric

My memory leak problem.

by ken jones

Everyone: It is hard to believe that X is the problem. It came with Fedora 4 and no one else seems to be reporting it as a bug. I have another Fedora 4 machine that does not display this swap space problem. Karl's idea of looking carefully at my drivers is a good one. This machine has more than one special driver. It is late now. I am tired. I shall pursue this track tomorrow or Friday. If anyone else is interested in the cut and paste of ps auxw lspci uname -a lsmod vmstat dmesg tell me. I will send you a copy. Thank you all:-) Ken Jones Thank you.

Keep watching this process if it's memory size grows then there may be a memory leak eating up your memory.. I'm not a fedora expert, are there any X updates? have you run yum or updated your system? What version of X are they using? perhaps send your /var/log/xorg.0.log [root@kjones-fedora kjones]# lspci 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R300 NE [Radeon 9500 Pro] 01:00.1 Display controller: ATI Technologies Inc Radeon R300 [Radeon 9500 Pro] (Secondary) I see you have an ATI graphics card. Do you know what video driver you are using? perhaps there is a problem there.

The graphic didn't come through here. I bet you're using a binary-blob kernel module (e.g. Nvidia) which is making your system crash. The other possibility is you have an app with a memory leak, using 'ps avx' would help diagnose that. --Andre __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Should be able to see what the cause is. send us more info on your system do these commands and paste us the results: ps auxw lspci uname -a lsmod vmstat dmesg

I have setup a few servers with 1TB, 1.5TB and 2TB doing NFS, mainly for video streaming and at most 15-20 NFS clients. Using kernel 2.6.15.7 for a while now with no performance complaints. I have seen 15 NFS clients streaming DVD quality mpeg2 video (9mbps) work nicely. Getting over 2TB, tho starts to be a lot of disks and there are heat problems, also problems finding enough drive bays. -- Karl Hiramoto http://karl.hiramoto.org/

Getting a box with a bunch of 3ware controllers talking to SATA drives in hot-swap bays might be the ticket. You'll get decent performance too, though not stellar. Software RAID can be faster, but the 3ware can/should insulate you from the hardware hot-swap issues. Should. Take a look at JetStor, or the ATAbeast boxes. They were around $14k/2Tb three years ago, so they must be cheaper/better now. What about backups? John

Anyone have suggestions? i need: * >= 5TB disk space * iSCSI, ATA over Ethernet, or NFS mountable to linux >= 2.6.15 *RAID (must survive single disk failure) and must know when a failure happened. * $$/TB is important. * Must be able to sustain minimum 10MB/s disk read on Gbit network. normally these will be big multimedia files. Yes, i know i can buy a linux PC, and slap in 11 or more 500 GB disks and do this RAID5. Something off the shelf, and easy to service would be nice. -- Karl Hiramoto http://karl.hiramoto.org/
