| detrate | anyone here familiar with audio interference caused by the ethernet cable? | 18:34 |
|---|---|---|
| detrate | after a system crash, I rebooted to find I have noise interference when I browse the internet... | 18:35 |
| detrate | _really_ annoying | 18:35 |
| detrate | I'm using a Audio 2 DJ external USB sound card... so it's a little difficult to separate them from each other | 18:35 |
| detrate | what gets me, is I didn't have this problem prior. I'm on ubuntu 10.10 with ALSA for sound | 18:35 |
| holstein | ive heard wierd things when moving a mouse before | 18:36 |
| holstein | weird* | 18:36 |
| holstein | usually with just internal cards | 18:36 |
| holstein | could it be that the USB card and the network adapter share IRQ | 18:37 |
| detrate | yeah, I'd expect internal more | 18:37 |
| holstein | cat /proc/interrupts | 18:37 |
| detrate | can I explicitly define which IRQ they use? | 18:37 |
| holstein | i think you can hack that somehow | 18:38 |
| holstein | i usually look in the bios | 18:38 |
| holstein | and if the settings arent there, i get really bored of trying to fix it ;) | 18:38 |
| holstein | its never been something i needed to worry with on a production box | 18:38 |
| holstein | detrate: you dont have the noise when the network is disabled? | 18:39 |
| detrate | I don't really know what I'm looking at here: http://pastebin.ca/2023714 | 18:39 |
| detrate | correct | 18:39 |
| detrate | if I unplug the ethernet | 18:39 |
| detrate | it's clear as day | 18:39 |
| holstein | this is with JACK running? | 18:39 |
| detrate | no, alsa | 18:40 |
| holstein | looks to me like | 18:40 |
| holstein | 44: 181517 181453 180936 181545 PCI-MSI-edge eth0 | 18:40 |
| holstein | your network is off by itself | 18:40 |
| holstein | detrate: i would say, try JACK | 18:40 |
| holstein | thats the pro level tool we have | 18:40 |
| holstein | maybe just in the spirit of trouble-shooting | 18:41 |
| detrate | how is that going to effect my other applications? | 18:41 |
| detrate | I use this machine for many thing | 18:41 |
| detrate | s | 18:41 |
| holstein | well, it wont do anything to try it | 18:41 |
| holstein | JACK is there | 18:41 |
| detrate | alright | 18:41 |
| holstein | you just run it when you want to use it | 18:41 |
| holstein | and stop it when you dont | 18:41 |
| detrate | do I need to restart or just logout to get it functional after install? | 18:41 |
| holstein | depends | 18:41 |
| holstein | not really a 'this is how to use JACK' type of thing | 18:42 |
| holstein | depends on the hardware | 18:42 |
| detrate | ah | 18:42 |
| holstein | and config | 18:42 |
| holstein | detrate: why did the system crash? | 18:42 |
| detrate | because maintainence replaced my refridgerator and apparently left the power off for over 10 minutes because my UPS can last about 10 minutes | 18:43 |
| holstein | hehe | 18:43 |
| holstein | well, i would think that is un-related then | 18:43 |
| holstein | hmmm | 18:43 |
| holstein | i would probably get a 10.04 live CD | 18:43 |
| holstein | and see if you can hear it then | 18:44 |
| holstein | try and get the installed OS out o the equation | 18:44 |
| holstein | make sure its not hardware related | 18:44 |
| holstein | and try the JACK thing | 18:44 |
| detrate | alright | 18:44 |
| holstein | and go from there | 18:44 |
| detrate | I can try the card on another computer, I know it's not the headphones / speakers | 18:44 |
| holstein | AH | 18:44 |
| holstein | yeah, that would be a good call too | 18:45 |
| detrate | I already testd them on the internal audio | 18:45 |
| detrate | and the ethernet is what's causing the interference | 18:45 |
| detrate | so weird and annoying.. | 18:45 |
| detrate | I just want to listen to nice clean music :( | 18:45 |
| holstein | no interference with the internal card? | 18:45 |
| detrate | not at all | 18:45 |
| holstein | yeah, i would do that first then | 18:45 |
| holstein | test the USB on another box | 18:45 |
| detrate | try the card on another computer? | 18:45 |
| detrate | yeah | 18:46 |
| detrate | makes sense | 18:46 |
| holstein | maybe it didnt like being shut down? | 18:46 |
| detrate | if the card is wrecked, the building manager is getting a piece of my mind | 18:46 |
| holstein | detrate: no dought | 18:46 |
| holstein | a piece of mind, and a bill ;) | 18:46 |
| detrate | yeah, it's clean on the other computer | 19:12 |
| detrate | so soundcard isn't ruined, that's good | 19:12 |
| detrate | doesn't help me understand the "software" issue though | 19:13 |
| detrate | and fwiw, I run the ethernet cable through a surge protector too | 19:13 |
| detrate | (I tested it direct and still same issue) | 19:13 |
| holstein | detrate: how about the USB on the computer? | 19:21 |
| holstein | if you boot a live CD and test it | 19:21 |
| detrate | tried every slot | 19:21 |
| detrate | no I haven't done the livecd test yet | 19:21 |
| detrate | I have to burn one first | 19:21 |
| holstein | you could take the operating system out of the loop | 19:21 |
| detrate | not sure I have one handy | 19:22 |
| holstein | its a stretch anyways | 19:22 |
| detrate | yeah, I feel like it's either config or bios at this point | 19:22 |
| detrate | maybe I should check the bios first | 19:22 |
| detrate | though, I feel like my clock would be reset if something in there changed | 19:22 |
| holstein | and i cant imagine what setting would caust that noise | 19:22 |
| holstein | from the bios settings | 19:23 |
| detrate | ifinternetisonmakenoise=1 | 19:23 |
| detrate | definitely feels like the USB power isn't "clean" | 19:23 |
| holstein | lol | 19:24 |
| detrate | omg gross, I restarted and it's ALL static now | 19:28 |
| holstein | interesting | 19:28 |
| holstein | i have a laptop like that though | 19:28 |
| holstein | the USB is borked bad | 19:28 |
| holstein | i have a little USB maudio transit | 19:28 |
| detrate | hmm | 19:29 |
| detrate | I have a usb hub I can try but I don't think that will help anything | 19:29 |
| holstein | and i screwed around with it for about 20 minutes before i went to another box | 19:29 |
| holstein | the machine came to me like that | 19:29 |
| holstein | SO i have no idea what caused it | 19:29 |
| holstein | its got other little issues here and there too | 19:29 |
