[alsa-devel] Problem with ALSA Capture and Playback : start_delay
by Nobin Mathew 10 May '07

10 May '07

Why start_delay=1 for capture and start_delay=0 for playback what this means I have one app which does both capture and playback, but when i tried to read ALSA buffer(capture) periodically it gives ALSa buffer overflow error. what my app does is read from ALSA (capture mic) and write to ALSA(playback). In this case for both Capture and Playback setting i am using start_delay = 0. But if i am giving some delay between Read and Write no overflow error happens Any idea why this happens Thanks

Re: [alsa-devel] Can someone verify support for "AzTech Sound Galaxy Nova 16 Extra II-3D - using AZT-2316/R Chipset - FCC-ID:I38-MMSN846" ?

I already installed dos + the drivers and ubuntu, So I'll try working with that. As far as I can tell from the win95 driver name, the "AzTech Sound Galaxy Nova 16 Extra II-3D - using AZT-2316/R Chipset - FCC-ID:I38-MMSN846" is full-duplex : In : http://www.aztech.com/support_download_soundcard01.html : 2316FD95.ZIP 90,526 Windows 95 Full Duplex Audio Driver Version 4.8.0 Build 1128 I will try working with the software first, then probably either the epprom or the jumper (since I have dos + drivers working I'm tempted to try the epprom first ;-) ) I can't at the moment compile in that machine (My poor little xubuntu is barely working as it is, I don't even dare installing samba let alone a dev-env of any sorts..., maybe when I'll get everything working I'll install slackware, I decided gentoo is not a good idea ;-) ) so I won't be testing your drivers any time soon :-( , I do however hope you'll submit your drivers cause a non PnP driver can't hurt and waiting for confirms on such old hw will be point-less... When I'll have results I'll let you know... Also, I'm CCing the mailing list now as pair request... Thanks Rene, Ram Kromberg ramkromberg(a)mail.com

[alsa-devel] Can someone verify support for "AzTech Sound Galaxy Nova 16 Extra II-3D - using AZT-2316/R Chipset - FCC-ID:I38-MMSN846" ?
by ramkromberg＠mail.com 10 May '07

Hello alsa devs, I have an old "AzTech Sound Galaxy Nova 16 Extra II-3D - using AZT-2316/R Chipset - FCC-ID:I38-MMSN846" which I know to work on windows 2000 natively and on other windows using drivers from http://www.aztech.com/support_download_soundcard01.html, however, I was unsuccessful in using it in linux ( I tried many dists, but my most recent failure was with xubuntu 7.04 which have the most recent alsa). I believe the card is unsupported in alsa and I was hoping someone might be free to help me with this legacy card ? Since the card is unsupported I figured this should go the devs. * Their is this piece of code which might be relevant: http://www.gelato.unsw.edu.au/lxr/source/sound/isa/azt2320.c 21 This driver should provide support for most Aztech AZT2320 based cards. 22 Several AZT2316 chips are also supported/tested, but autoprobe doesn't 23 work: all module option have to be set. * I'm unsure of what it means to configure manually or how to do so... I do however have the card working currently with windows 2000 so if its a question of IRQ and DMA, I can find those with relative ease. * I obviously tried modprobeing the snd-sgalaxy driver/module, with no success - possibly related ? Thanks Ram Kromberg ramkromberg(a)mail.com

[alsa-devel] Sound on SMDK2410
by Jose Henrique Spahn Torres 10 May '07

10 May '07

Hi all, I am trying to get sound working on a SMDK-2410 evaluation board. I compiled kernel 2.6.20 with alsa-driver-1.0.14rc4. However, I could not find the specific uda-1341TS driver for this board. I would like to know the status of this driver, if there will be one some time soon. Thanks, Henrique

That was the idea; the other ASoC boards do similar things. > Are you planning on submitting a stub that enables these? Or is this just > to be a placeholder until some board wants them? I suppose I can submit my AC97 board code, it does not depend on anything that is not already submitted. I'll add the ac97 board code to the patch and re-submit it. Thanks, Manuel Lauss
