RE: [linux-audio-user] Re: Soundblaster Live w/Live Drive

(I can't be sure, I don't own one) The multichannel support is probably only available when you send an encoded digital stream to the card (something like AC3 for example) and the card then decodes it with an onboard chip for multichannel sound. Cards like these are generally not true multichannel cards in the sense that you would use for professional audio applications. They are consumer grade cards that feature onboard multichannel decoding so that Joe wintel user can have his surround sound while watching DVDs on his computer. You could try looking around in the documentation available on ALSA's sound card matrix, online documentation or wiki. regards -Reuben

Yeah, it looks to be, but just to make sure, what all should I see to make sure? (BTW I got it working decently using the sdl option... I don't know how preferable that is.) Thanks, Matt

[linux-audio-user] noisy capture->playback

by David

Hello all ! What could I do about the following problem ? I have an M-audio delta66 + omni I/O (preamp/breakout box). This card has an onboard digital mixer that allows hardware monitoring of inputs. - when setting this mixer to directly route a HW input to a PCM output, the sound is perfectly fine. The signal goes through both an A/D and a D/A conversion before reaching my ears. I suppose that if I had a ground loop problem (or other analog noise source), I would hear it with such a setup. - now, when using jackd to route (with no jack client in between) the alsa capture port associated with the HW input to a playback port, the sound is full of horrible "blips". I use : - IRQ #10 for the delta66 (I even disabled the USB controller of the motherboard which used IRQ#11, with no better results). - a patched for LL 2.4.19 kernel, ext2 filesystems and hdparm'ed HDs. - alsa 0.9.6 - a tmpfs work directory for jackd that I start with '-R' as root. How could I isolate the source of this very annoying problem ? Is there a way to route an input to an output through ALSA only without using jackd (and the hw mixer too of course) ? Maybe that would help tracking down the culprit ... I'd appreciate any hint on this. Thanks a lot ! -- David

You also might try the gui "qjackctl" or its little sister "qjackconnect" if you don't want too much gui. If you run qjackctl, be sure to set it to "hw:0" rather than the default if you want all your ins and outs to show up. M

[linux-audio-user] Mplayer

by BrbrOfSvl＠aol.com

So, I have this HDSP/Multiface and all the Alsa drivers I could want, but when I use mplayer for anything I may as well be watching a rice krispies commercial. The video is fine when the sound is off, but if the sound is on, the video and audio both jump and snap and crackle. I turn it off before it gets to pop... is there anything special I can do? Do I need to recompile mplayer with or without some special flag, or is there some option I can simply run when I bring up the program? Thanks, Matt

[linux-audio-user] [OT] sidetalkin

by Frank Barknecht

Hallo, well, some of these things run Linux and it has to do with audio signal transportation somehow so I guess this link is not *totally* off topic: http://www.sidetalkin.com/ ;) Also there's one guy with a cool mixing console up his ear! ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] Loop points with libsndfile

by Peter Bessman

I should post this to either libsndfile-dev or lad, but I'm already subscribed to lau so I'm gonna test the waters here first. Does anybody know if libsndfile supports sound loop points and playlist data chunks? (Erik, I know you're out there...)

RE: [linux-audio-user] Soundblaster Live w/Live Drive

by Reuben Martin

The .asoundrc setup should have little to do with what multiple io ports show up. When you connect jack to hw:0 any available ports on that device should show up. You would only need features available from .asoundrc if you wanted to use a plug interface of some sort, and those things are dog slow. regards -Reuben -----Original Message----- From: Adam King [mailto:aking@lgh.com.au] Sent: Sat 11/1/2003 7:13 PM To: linux-audio-user(a)music.columbia.edu Cc: Subject: [linux-audio-user] Soundblaster Live w/Live Drive Hi all, I've just purchased a Soundblaster Live Platinum 5.1 w/Live Drive. I've got it all set up and working with the ALSA drivers but I am having trouble with JACK and the .asoundrc file. I want to be able to have multiple in/out ports. Example, I want to be able to use jackEQ and send the master output to speakers, and the monitor output out to headphones. Does anyone have a same .asoundrc file or can give me tips on how to set it up? I've tried reading the ALSA docs but am not having much luck. Thanks, - Adam
