    Re: EMU 0404 USB new thread

    I managed to make E-MU 0204 to work under Ubuntu 10.04 and 10.00. More info here:
    http://ubuntuforums.org/showthread.php?t=1713011

    Edit: It seems that Ubuntu 11.04 already has this patch applied. At the time of writing this 11.04 is still in beta.

    Re: EMU 0404 USB new thread

    I am using Ubuntustudio 10.04 and Alsa 1.0.23.
    The 0404 plays analog out is working.

    Recently, I tried to use the SPDIF output of 0404 USB.
    But get error messages such as:

    snd-pcm failed OR pcm_hw_params_setting

    depending on the playback software used.

    I cannot find the "snd-pcm" nor "pcm_hw_params_setting" strings in config files.

    Please advise.

    Re: EMU 0404 USB new thread

    Hey,

    I'm was having the same issue under Fedora 16, when I turned down the master volume in gnome only the left channel was going down.

    I fixed it in Sound Settings > Hardware, selected the E-Mu and changed the profile to Digital Stereo Duplex IEC958.

    Hope it works for you too !

    Cheers

    New Flash plugin 11.3 (part of Chrome 20) works pretty bad for me with E-Mu 0204. When I playback audio in some music player, and open page (in Chrome) with Flash content at the same time, audio become crackling until I stop playback and terminate flash plugin (or close the Chrome). The other workaround is move audio channels from E-Mu to integrated audio adepter (or to HDMI audio output) in pavucontrol.

    Looks like this Flash update expose some deep ALSA bug (or maybe PulseAudio, but I really doubt in this). With 11.2 In Firefox this bug is not reproducible.

    So, anyone experience same issue?

    Looks like this is not issue with driver, but problem with Flash 11.3 PPAPI. There is big problems with audio playback in new PPAPI Flash 11.3 even on Windows. Example: https://code.google.com/p/chromium/i...tail?id=134193

    Re: EMU 0404 USB new thread

    Has anybody ever got this thing to record at 24/192? Mine plays back 24/192 flac files w/ no problems and it can record at 24/96 by using the following command:
    arecord -f S24_3LE -c2 -r 96000 -D hw:1,0 >test2496.wav

    But, if I try this command:
    arecord -f S24_3LE -c2 -r 192000 -D hw:1,0 >test24192.wav

    I get nothing but static.

    I've read that you have to use the windows driver to set the sample rate. Is this true?? If this can play at 192khz I'd think that _somehow_ it could record...

    P.S. This was tested using Ubuntu 12.10 which has alsa 1.0.25

    Re: EMU 0404 USB new thread

    Tested 24/96 (worked) and 24/192 (didn't work)
    I also found out (I don't do much recording and usually stick with 41.1) that jack uses "SND_PCM_FMT_S32_LE, which is the format used by all current 24 bit audio cards except for some USB interfaces that actually use 24 bits rather than 24-packed-in-32-bits." does that affect any of you (like when recording in ardour)?

    Re: EMU 0404 USB new thread

    Jack sits on top of alsa so that really has nothing to do with the problem. The is issue is with the alsa driver itself.

    If arecord doesn't work at 192khz, then NOTHING is going to work - not jack, not pulseaudio, not sox, not <insert software here>. ALL that stuff sits on top of alsa. It's kind of like saying "hey my telephone doesn't work" when you don't even have dial tone when you pick up the line.

    On a more positive note though, I did install the very last 0404 driver ever released from creative labs onto a Windows Vista laptop (I feel sooo dirty), upgraded the firmware to ver8.??, and was able to record at 24/192 using audacity with the directsound drivers. So this thing *can* record at 192khz but it is a 100% proprietary solution.

    Now, from what I can understand, in the windows world, directsound has been deprecated by MS and now sits on top of some other layer of software. HOWEVER, there are also some OTHER drivers called ASIO drivers that are similar to alsa in the linux world, that give you direct low-level access to the sound card itself.

    Soooo, based on this information, *I think*, to truly get 24/192 recordings from this sucker, you have to (in Windows)

    1) have an ASIO driver installed for your sound card (this may or may not be included with the driver that comes from creative labs)
    2) capture sound using some software that uses the ASIO interface


    I know this is a super long winded post but I've been trying to figure out what's the cheapest possible way to record high-quality 24/192 digital audio for taping live music. And from what I can tell, a used E-MU 0404 is *ALMOST* there. If I have to use windows, I guess I will but it would be much simpler if this thing worked with linux. Or, maybe I'll settle for 24/96 like everyone else.

    I know it's insane to even want to record at 24/192 but hey, who cares, disk space is cheap and if it's good enough for Neil Young, it's good enough for me.

    Re: EMU 0404 USB new thread

    OK, I have confirmed that there is no way to record 24/192 w/ linux and the e-mu 0404. BUT, I did get it to record 24/192 on a vista laptop by installing the latest drivers, compiling ASIO support into audacity and finally, then I can export 24/192 wav and/or flac files. Not elegant but it works.
