  1. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    Hi,

    Thanks for the suggestion regarding using the generic kernel. I installed this and reboot, before trying to record again in Ardour.

    I found that I was getting Xruns at ~30sec intervals...
  2. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    Thank you both,

    I've tried out AV Linux, which is giving much the same results in an 'out of the box' state. I am going to take a break from trying to get it working correctly on the laptop, and...

    Hi,

    Thanks for looking at the outputs. I wasn't 100% on how to determine which irq the soundcard was using however you've confirmed what I was thinking about it being on 16.

    I've not read...
  4. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    Hi,

    I did a bit of research based on your post and reckon you mean the Intel SmartStep BIOS feature. Having disabled this cpufreq-info is no longer able to report back on the clockspeed of the...
  5. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    Hey,

    All of my testing on the laptop has been with an installed version of 12.10 x64, however I did try once using a Live USB as I was curious (it seemed to work on my desktop this way!), however...
  6. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    I think I can happily eliminate any potential issues with the hardware interface itself: I booted my desktop from a live USB containing 12.10, and it worked fine with the Focusrite Scarlett @ 96kHz...
  7. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    Hey,

    I was pretty optimistic after reading the post regarding blacklisting the Intel chip, however unfortunately it didn't make any difference in terms of Xruns (although it did remove the option...
  8. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    Hi,

    Yes this is a separate 'mini-issue' I'm having: the ID of the card in qjackctl will occasionally change! What I normally do is check (in the same manner you've described) that everything...

    Certainly:



    0 [Intel ]: HDA-Intel - HDA Intel
    HDA Intel at 0xfbf00000 irq 49
    1 [USB ]: USB-Audio - Scarlett 2i2 USB

  10. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    Hi,

    The laptop is a Dell Inspiron N5010 (UK FCG04). I've had a look in the BIOS and there's an option to disable the NIC (which actually ends up disabled wired *and* wireless), but not much else...
  11. [ubuntu_studio] Re: Unable to achieve a low latency with Focusrite Scarlett 2i2

    Hi CrocoDuck,

    Thanks for the reply; just checking in with how I've got on so far.

    After running the Quickscan script I was able to make some tweaks and create an sh file that set some of the...

    I am running Ubuntu Studio 12.04 x64, 3.2.0-23-lowlatency on a Dell i3 M350 (2.27GHz) laptop with 4GB RAM. I typically run with networking disabled.

    I recently bought a Focusrite Scarlett...
