**** Note -this post was edited to reflect a more accurate main title****

Sound output using mLan as the audio interface is stuttery and glitchy. This is even when the onboard sound is disabled at BIOS level and drivers removed. Makes no difference.

It’s like something is constantly trying to interrupt the sound output. I have investigated MCSS and it seems this is not the culprit either and indeed, is required for audio to run correctly on W7.

Just tried it on my laptop as well, which also runs W7, but the 32 bit version, with a different soudncard, but still with a TI firewire chipset.

Exactly the same problem, really glitchy audio playback when using either Windows Media Player or Winamp and using the Yamaha WDM driver as the default audio output.

Just playing bog-standard MP3 files.

However I have discovered on teh laptop it has too small a processor so I will try the XP version of the driver.

Can you identify and post the firewire chipset detail and what motherboard you have?

Aside from what Yamaha has posted as strictly “non-compatible” firewire chipsets there appear to be other chip sets suspect that are causing grief, such as JMicron 381. However, it is very clear which chipsets they do support with their drivers.

If you’re getting BSOD, then I am more inclined to suspect IRQ or driver conflicts with other devices, or quite possibly the BIOS on your motherboard.

Thanks T-Bone...As I said the exact same symptoms occur on two totally different PC’s. One has the TI chipset (the laptop) and the other the Adaptec PCI card which I had previously tested as working correctly.

The laptop uses W7 but in the 32 bit version. Apart from that, as I said the ONLY common element is the Yammie firewire driver. The hardware on both is obviously completely different, yet the problem is exactly the same.

I too suspected an IRQ, but I cannot find a cuplrit. I have played the file while removing (stopping) services on the PC one by one, until there was essentially nothing else running in the background.

*****Edited to update*********

I re-checked and on the desktop PC the PCI slot is sharing an IRQ with the Realtek PCIe slot, however W7 reports no conflicts. In any case, with the ACPI sytem, a user cannot manually re-assign IRQ’s.

On the laptop the 1394 adaptor has its own dedicated IRQ assigned.
******************************

As I have 4gig of ram there is no need for a paging file, but I even re-instated that to see if it made a difference.

When playing audio using the Realtek (on the PC) or the Sigmatel (on the laptop) no problems at all, and the Yamaha USB midi works perfectly alongside too :)

As for the BIOS,I have checked that too and all is set for normal operation, no tweaks :)

But, try using the fireiwre driver and then all the problems happen.

There is one thing I have not tried and that is to revert to Windows XP, load the XP versions of the Yammie drivers/software and see what happens.

Thanks for offering your assistance though :)

First, let’s be clear the Yamaha Steinberg Firewire driver 1.51(YSFW 1.51) is not an mLAN driver.  TThe YSFW driver and the mLAN driver are two different things.

There are two Yamaha Steinberg Firewire drivers for Windows 7 - one for 32 bit systems and one for 64 bit systems. Just making sure that you downloaded the right drivers for each of your computers.

Yamaha Steinberg FW Driver V1.5.1 for Windows 7/Vista 64bit

Yamaha Steinberg FW Driver V1.5.1 for Windows 7/Vista/XP 32bit

To be honest, we personally not have not done much testing with Winamp, but it works fine on our 64 bit system and Windows Media Player and other apps that use WDM. Also a number of other posters have reported back that they ahd everything working fine although again no one mentioned WinAmp.

Of course Sonar could use ASIO so you may want to try setting that up just to confirm that the YSFW driver is working correctly with ASIO, if you haven’t done that already.

Thanks Yamaha US...Yes I have double checked the correct driver was downloaded.

As far as I know the mLan driver does not work with the mLan16E2 card that I have installed. Correct?

You see the thing is if it was only doing this on one PC I could accept there would be some further checking I need to do, but as the exact same symptoms occur on two TOTALLY different systems, it was why I was doubting the driver.

By the way, the saem thing happens with EITHER Winamp or the Windows Media Player, so I think that rules out a Winamp issue.

But if others are not having issues it MUST be soemthing at my end. But I have spent a day and a half on this with no joy at all.

Just to be sure I re-downloaded and installed it again (after removing the existing one).

Still the same. Will the mlan16e2 work with Windows XP with no issues? Maybe as a last resort I could run XP as a dual-boot system with Windows 7. I mean I would rather not as Windows 7 is SO much better than XP in every way.

Failing that, I jsut give up on the idea of using the mLan16e2 and go back to a standard fw audio interface and just use the USB MIDI on the XS6??

This is soooo frustrating, especially as I am convinced it is something small. I think I will try re-installing the OS, but only the basic system and then re-install the YSFW drivers and see what happens then…

Thanks again for looking at the thread :)

Right just re-installed W7, and the Chipset. Installed FW driver, and NO glitches at all. Runs smooth as. So now I need to re-install all the drivers and programs one by one to try and find the culprit.

As for the laptop...It only has a 1.33gig dual core processor. When I checked the Yamahasynth site the minimum for FW is 1.66 so I guess that is the reaosn it is glitching on the other. I have not tried upping the latnecy past the 50ms as yet. I think though if I want to use mLan live, I will have to buy a new laptop.

Maybe best to ditch mLan in favour of something else I think.

I found that the older W XP drivers require a single core 1.4 gig processor, so maybe I could go that way, use XP..

BUT, I have upgraded the firmware on the mLan16E2..Will it still run with the older mlan driver/tools package?

thanks

Righto, found the culprit and its probably the worst thing to be glitching..The nVidia graphics card.

I post it here as nVidia is a popular graphics card for a lot of users. The thing to watch out for are the cards with HDMI.

It is the HDMI high definition aduio drivers that are causing the problem.

They get installed automatically with the display drivers, and even going into control panel/remove programs, which DOES give an option to remove all nvidia drivers EXCEPT video, but even that does not work.

So over I go now to nvidia forums and see whats what.

Perhaps a dual boot system with one running full software for games etc etc, and the other for music using ONLY the default Windows 7 video drivers might be the only option.

I will keep posting info here as the newer graphics cards with HDMI fitted are becoming the “norm” in new designs, so I am sure there may be others trying to use the Yamah Steinberg FW driver on the same PC as the nVidia, and perhaps having the same issue.

It does not appear that the HDMI audio causes any grief with teh motherboard based audio (in my case Realtek) you just need to set the onboard device detection to “ON” instead of “AUTO”.

Hi miden,

tell me please, did you find the solution to your problem concerned nvidia audio driver ?

perhaps, I have the same troubles and I don’t know what to do.
I tried different laptops under Windows XP with different chipsets Texas Instruments, Ageres, O2 Micro. no chance!

I have nvidia card on my laptops. I’ve just read your issue… so I’m curious if there is the way to resolve this problem ?

Thank you for your aid !
