Tascam DM 4800 keeps crashing after WDM audio stops playing

[WillRan]

After reading much about this console, I was able to find it for brand new for about 1,700 which came along with the firewire card. I am loving this console and how flexible it is so i figured i started messing with the routing. I followed cmaffia's guide on getting it to work with windows and I didn't a fault with it until i tried using WDM to bring audio into the mixer and back into the computer. The music plays all the way through but if it stops or you close out the application before it stops then the whole computer crashes with the iffwdm.sys being at fault. So i was wondering if anybody else had a problem with this?

What firewire driver version are you using? Provide a screenshot of the WDM setting in the Tascam Control panel. What application is crashing? I have not experienced any issue with playing back audio files with Windows Media Player in Windows 10.

@cmaffia I am using the driver 1.30f9 and the firmware is at 1.10. Any application that is playing the WDM audio crashes after the song is finished or if you quit the application. Now it seems that even the DAW i'm using isn't letting me use tascam's asio. Here's the screenshot i took and i realized something. The system info states that I'm on windows 8.1 which I am definitely not on, as im sure it's windows 10 pro. So weird

I suggest you increase your buffers. Start at 256 and set to normal for starters. I have a more powerful CPU than you and my DAW would choke with those settings at 88.2kHz and you're set at 96kHz! The app in your screenshot even recommends NORMAL mode. Reporting Windows 8.1 rather than Windows 10 is not abnormal. Tascam would need to update the driver to report the correct OS. I would also make sure that if you have on board audio (built in your motherboard), that it is disabled at the BIOS level. Also make sure Windows default sounds are disabled.

@cmaffia So i tried starting off on 256 and set it to normal mode. The songs play, but now they stop at a certain point in the song. I tried increasing the buffer setting but still same result. To keep the computer from crashing, i have to switch playback devices.

 

[cmaffia]

Did you check my other suggestions?

 

[cmaffia]

Oh! Did you make sure your WDM audio settings match your board's sample rate which you have set to 96khz? By default it is set to 44.1 kHz and doesn't change automatically. You need to manually change or else you will have this issue.

 

[cmaffia]

Follow these instructions. It should be the same procedure in Windows 10. You need to choose the IF/FW of course. Set to 24bit 96kHz or whatever the DM is set to.

@cmaffia I'm currently at work right but when I get home I'll report to you and see how it goes

@cmaffia So i just got home and make a few configurations to my computer and the mixer and now it plays audio through WDM all the way without crashing! You're awesome man! What I did first was go into my bios and disabled any onboard audio there was, then i changed the sample rate to 88.2k since i didn't really need 96k to begin with, make sure the WDM and the mixer sample rate was set to 88.2k, for some reason I have to set the input/output on the card to 32 tracks since for some reason it was acting funny with the output being at 16 tracks (I dunno with this thing), set the buffer to 256 and to normal and now its working! I'm still doing several test just to make sure before i configure my daw

Also, is there a reason why every time i go on the internet the card status will unlock? I know with my old tascam audio interface (US 200) I always had to disable the internet/wifi card if i didn't the audio to freeze up or get distorted. You think it might be the same reason for the firewire card?

 

[cmaffia]

You need to match the WDM kHz playback to whatever the board is configured to or else you'll have a mismatch. This results in pops and clicks upon playback or generally weird audio issues. Network card enabled can affect FireWire performance when they share they same interrupts. I usually disable my network card until I need it.

 

[cmaffia]

Also confirm you're using the legacy OHCI 1394 FireWire driver and that power management parameters for all USB devices and hubs is off in device manger. I usually go through every device in Device Manager and disable power management for anything that has that parameter. Look at my notes for optimizing Windows 10 in my Windows 10 compatibility sticky.

 

[cmaffia]

I've updated the Windows 10 Compatibility thread to include configuration changes for WDM playback.

Alright finished up all my testing and glad to say everything works now. And also to my last comment, I figured out it was my Wi-fi card that was causing the random bouts of unlocking the card whenever it was on, so now i keep it turned off whenever im playing music or working in the daw. Thank you so much! @cmaffia
