Question for those with M-audio audiophile 2496 cards

  • mick.ca
Posted: Mon, 07/16/2007 - 09:52
What are the M-audio audiophile 2496 sample rates? I checked the site for m-audio and while other cards show various sample rates, this one does not. Is it fixed at 96kHz or will it do 44-192kHz @ 24bit? I was thinking of purchasing one to replace and/or run along side my Audigy.

NO Sound on this card beta3 upgrade

Hi All I seem to have lost all sound with this card since last update. Anyone lese have this problem? Jack will not fully start and Ardour will start the session but not actually run the transport. I get this from jack messages: ******************************************** ack: JackRequest::ActivateClient Jack: JackEngine::ClientActivate ref = 2 name = qjackctl Jack: JackProcessSync::TimedWait time out = 106660 JackProcessSync::LockedTimedWait error usec = 106660 err = Connection timed out Jack: JackProcessSync::TimedWait finished delta = 106746.0 Jack: JackExternalClient::ClientNotify ref = 2 name = qjackctl notify = 2 Jack: JackClient::kActivateClient name = qjackctl ref = 2 ****** All ok so far! Then this: ***************************************************** ALSA: poll time out, polled for 7999034 usecs JackAudioDriver::ProcessAsync: read error, skip cycle ALSA: poll time out, polled for 7999023 usecs JackAudioDriver::ProcessAsync: read error, skip cycle Jack: fPollTable i = 1 fd = 5 Jack: fPollTable i = 2 fd = 15 ALSA: poll time out, polled for 7999023 usecs JackAudioDriver::ProcessAsync: read error, skip cycle Jack: fPollTable i = 1 fd = 5 Jack: fPollTable i = 2 fd = 15 ALSA: poll time out, polled for 7999024 usecs JackAudioDriver::ProcessAsync: read error, skip cycle Jack: fPollTable i = 1 fd = 5 Jack: fPollTable i = 2 fd = 15 ALSA: poll time out, polled for 7999023 usecs JackAudioDriver::ProcessAsync: read error, skip cycle Jack: fPollTable i = 1 fd = 5 Jack: fPollTable i = 2 fd = 15 ALSA: poll time out, polled for 7999023 usecs JackAudioDriver::ProcessAsync: read error, skip cycle ALSA: poll time out, polled for 7999022 usecs JackAudioDriver::ProcessAsync: read error, skip cycle Jack: fPollTable i = 1 fd = 5 Jack: fPollTable i = 2 fd = 15 ALSA: poll time out, polled for 7999018 usecs JackAudioDriver::ProcessAsync: read error, skip cycle *********************************************** So no more mastering for me so far. I also upgraded my Ubuntu machine ( on anther Drive , same machine) This has now stopped all sound and pulse audio does not see the card at all. Any ideas? Cheers Bob

pulse and 2496

The problem lies with the pulse audio server.....again you need to let all programs access alsa devs directly. Problem is that Ubuntu RedHat et all that are configured with Gnome all completely rely on the ever borked and useless pulse server! I have a thumbdrive version of fedora 12 kde 64 bit working with my 24/96 and intel hd audio and needed to turn off all pulse related activities to make sure the related deamons do not start at all. Audacity and Jack play fair and I achieve decent latency for 24/94 stereo recording... If I try 4 track in with ardour then clock dither happens and the sync can get messed up. I am looking for another 24/96 audiophile so that I can sync the clocks rather than trying to use the onboard in combination for 4 track recording. I am just waiting for a new version of 64 studio to do a harddisk install on my working machine. I need the latest kernel 2.6.29 or better for wireless support and alsa intel hd audio at the kernel level. eric

Pablo, you are correct - I've been using my previous jack system for so long I never noticed it in the other tab. Thanks for clearing that up! Jarlath

ALSA MIDI?

Hi, I can be wrong but it seems strange to me that ALSA is not seeing the MIDI part of the Audiophile 2496. I wonder if the confusing tabs of the current version of qjackctl are not confusing you. In them: MIDI stands for JACK MIDI. ALSA stands for ALSA MIDI. AFAIK, JACK MIDI is in development, a few apps show JAck Midi ports but most of them (and this audio card) use ALSA MIDI. Don't you see the MIDI ports in the ALSA tab? Cheers! Pablo

Just installed studio64 3.0. audiophile 2496 does work but none of the midi devices appear in qjackctl so I'm assuming midi will not be functional. The analog audio on the other hand works excellently, if not far better, than Ubuntu Studio 9.04. I'm going to tinker around a little but if I can't get midi working I'll make a reluctant return to Ubuntu Studio.

take care not to buy the audiophile 192k, it is not well supported by alsa and a lot of users have problems with one using Linux. This is not the same card than the 96k. i used to have a M-Audio Audiophile 96k, and it works well since first version of Ubuntu, at very lox latency. Don't forget the "lspci" command in a terminal to check if the card is in the list, or not (may not well plugged...) Then envy24control is a good tool to manage your cards.

audiophile 2496 and delta 1010

I have an audiophile 2496 and a delta 1010 but only my delta shows up in my hardware. Is there anything I can do to make both cards install? Thanks in advance Randy

M-Audio cards work with envy24ctrl

64Studio has a mixer program called envy24control. Try setting the cards internal sample rate there first and then fire up qjackctl to set up the frame rate. Audiophile2496 is in my opinion excellent value for money and can do very low latencies in Linux - and sounds great, too.

I dont have any problem it

I dont have any problem it works very well at every frequencies. One i had this with Ubuntu studio it was only working with 48khz and i could not change. But i migrate to 64Studio, OpenSuse, 64Studio again and always fully workling. Have you tried alsaconf to fix it ? You'd better begin with before to plan something else.

latency, etc...

jk47, think that with the same frame period, if you increase the sample frequency, you will decrease the latency... It is the same for all sound cards. Toine

everything is

everything is right. Increase sample rate decrease latency. Increase bit definition too because a same buffer size will be empty faster

Midi works

since this first posting i have a M-Audio 2496 card and the midi is working just fine. I use the midi to trigger the drums in hydrogen and the synth racks so i have a lot less programming of drums to do. i can use the midi to play the drums "live" so to speak with the tracks i have laid. MiCK

Great!

Hi there, I use 64 studio (64 bit version) and was wondering if anyone was able to use MIDI on the 2496. I was thinking about buying one but I see conflicting information about whether the MIDI part of the card actually works. Cheers Steve

Hello all, I did find my answer. 8-96kHz with internal clock. 32-96kHz s/pdif clock. But how does everyone find it to work under linux?

well

It works great for me. The latency is usually less than 5 msecs and I don't understand why but when i was using 96k the latency was reduced down to 2msecs! Occsionlly I will run Azureus, Jack, Mplayer, Ardour, Hydrogen, and Firefox all at the same time. Sometimes I"ll get xruns when I'm really abusing my computer. I don't run Compiz-Fusion so I think that helps. :) No eye candy needed. I'd rather have faster swtiching windows nd greater audio quality. Midi also works very well. I've connected my Roland MC-303 and my MusicStar midi keyboard ($1 at a garage sale).

You may also decrease buffer

  • ehma
  • 08/21/07
  • Wed, 02/13/2008 - 20:02
You may also decrease buffer size, if it works well at 96Khz with 256ko it also works well at 48 with 128ko Latency time could means time to read whole buffer and increase bit resolution or frequencies sample rate will need to read faster whole buffer.

Good

I have a PCI 24/96. For me, it performs very well indeed in 64studio+JACK - I routinely use 22050, 44100 and occassionally 48000. I've not tried it any faster than that yet. Steve~

Hi Steve, Yeah,

Hi Steve, Yeah, understandingly so about the 44 and 48kHZ. There is a huge difference in 16bit, 24bit, etc. It took me a while to fully grasp the parallel between the two and how just the sample and bit rate really effect the sound quality of your recordings. Back in the day I had 16bit input (32bit float) and the difference today is huge with 24bit (solid). The 2496 will give me midi capacity for doing the odd fill track in Rosegarden and shortly Ardour. Thanks for the feedback, MiCK

24 bit depth???

Did you ever figure out if you could achieve 24 bit audio? I seem to be stuck at 16 bit in Jack. Best Regards, Ryan
