Hello, In order to troubleshoot audio on a Toshiba Portege R500, what do the people on this list suggest I use? Ubuntu? Knoppix? Suse? Slackware? Other? What version? Any special Alsa version I should be using to increase my chances of success? My problems: I recently bought a used Toshiba Portege R500 (R500-11Z to be exact) laptop which uses a Realtek ALC262 audio chip. It came installed with Vista, but I use Debian so I installed that instead, after making a dd copy of Vista. When Debian was installed, I couldn't get any sounds from the machine, no matter what I did. I couldn't remember if audio was OK in Vista, so I restored the dd Vista image to test. In Vista, at first I thought there was no audio either, but then, using headphones in a quiet room, I could hear some very faint sounds (barely audible) with all audio levels maxed. The situation is the same in WinXP; I can barely hear test sounds, and playing music I can just about hear that some sounds are produced, but I can't make out what music is playing, that's how low the volume is. I'm now guessing that the situation is the same in Debian, that I actually had audio working but at a ridiculously low volume level, but I didn't test with headphones then, just with the speakers, and the sounds from the hard drive and fan are way too loud (quiet as they are) to make any faint sounds from the speakers audible considering how hard it is to hear them with headphones. I haven't reinstalled Debian to verify this, as I'm now asking here what distribution you guys suggest I use for troubleshooting. It's not a mute issue; using mute the faint sounds disappear completely, and using the volume slider I can make the sounds even fainter until they completely disappear when cranked down to about 45. It's not the volume knob at the side of the laptop either, I've used it to turn audio up to 100 and down to (below) 45 in Windows. I have done some troubleshooting in Windows with different drivers (MS and Realtek), asked on Toshiba forums etc., and I even bought a new (used) audio/USB module on ebay in case there was a hardware problem. No luck. The mic, jack detection, volume knob and USB socket on the audio/USB module work fine, and Windows diagnostic tools says the audio device is working OK, so I don't think it's a hardware problem or that it's not getting enough power from the motherboard. So now I want to make another attempt at getting audio to work in Linux, as I don't seem to get anywhere troubleshooting in Windows. Which is where this mailing list comes in. I usually use Debian unstable and compile a customized kernel, but in order to troubleshoot the audio, what do the people on this list suggest I use? Ubuntu? Knoppix? Suse? Gentoo? What version? Any special Alsa version I should be using to increase my chances? Has anyone experienced similar problems with ALC262 (or similar chips) and have a solution ready? I've done extensive googling, but might have missed something... I'll be happy to post any lspci output, debug messages from dmesg etc. as soon as I've reinstalled with whatever distribution and version people on this list suggest. /L ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
