Bias FX 2 sound cutting



  • Hello. some help here please.
    I bought the elite version of Bias FX2.
    Sound is great but i have an issue.
    Every 5-6 minutes maybe less, i have a sound cutting for some seconds (2-3) .

    I am using

    1. windows 10 enterprise 1903 build 18362.418.
    2. Bias FX 2 Elite 2.1.5.4795.Release,
    3. DSP Engine 2179
    4. Build 64bit
      PC
    5. Processor Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz, 3401 Mhz, 4 Core(s), 8 Logical Processor(s)
    6. 32GB RAM
    7. SSD

    ASIO drivers
    sound card Steinberg UR22 MK2
    Buffer size 512 samples
    Input latency 16.485 msec
    Output latency 19.456 msec
    Sample rate 44.1 khz

    anybody with similar issue?
    I am using the same sound card with Bias FX for ipad without any issues.
    thanks.

  • @mike hi, I have already done this. It is showing the correct type of license.

    @esofron We've never seen this before, please send us a ticket for the follow up, thank you

    Definitely have a look at your DPC latency

    Let us know if you see anything on here

  • @pipelineaudio dont know if i used it correctly, but the system reported suitable for real-time audio.

  • i 've got this at the report. I will try the 32bit version of biasfx2.

    REPORTED HARD PAGEFAULTS


    Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

    NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

    Process with highest pagefault count: bias fx 2_x64.exe

    Total number of hard pagefaults 10
    Hard pagefault count of hardest hit process: 6
    Number of processes hit: 4



  • There aren't any pagefaults with the x32 bit version of biasfx2. definitely i will test it tomorrow extensible.

  • A2

    It never turned red though? Seems like thats not the problem...make sure it runs as long as the time it takes to normally drop out...in fact run it tiull it drops out and then maybe the log will have something good even if it doesnt turn red



  • @pipelineaudio unfortunately it has the same issue even with the 32bit version.

    never gets red.



  • Did some more tests.

    looks like it is the sound card and not the Bias FX2.
    I tested it with an irig hd2 and till now there is not any issue.

    I will test it more to be sure.
    Also, i will open a case at steinberg.

    thanks.
