Question for those with M-audio audiophile 2496 cards

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

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

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.

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

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 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.

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

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

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?
