    • Vewlix audio help

      While the speakers in my vewlix diamonds sound pretty good I noticed when having them turned up they sometimes tend to pop/crackle. I dont play games at ear bleeding levels, but I do like it loud enough to immerse myself in whatever game I'm playing. Since these are in my home and not in a noisy arcade this doesn't seem like an unreasonable request.

      Anyways, my first thought was to just replace the speakers as the factory ones are probably pretty worn. So I bought the Dayton Audio PC83-4's that where mentioned in the speaker replacement thread. These speakers are nice, but didnt solve the problem. They are also kind of a pain to replace so I dont recommend it unless you absolutely need too.

      Since I'm mainly using these cabs with a TypeX2, I decided to try a cheap SPDIF to Auxiliary converter. I didnt expect much from this but figured maybe the onboard analogue audio was the cause of the distortion. To my surprise this helped quite a bit, but introduces a "hum" noise into the audio. Ultimately I feel like the converter isn't recreating the bass notes accurately and thats why it sounds like an improvement. I decided I could live with this solution if I can eliminate the hum, so I ordered a ground loop isolator hoping it resolves the issue. But before I continue down this path of cheap Chinese audio peripherals, I thought I would ask if anyone else has experienced this and maybe had a solution?

    • No solution, but I just wanted to chime in and say I've had the same issue (speaker crackle in both of my Vewlix cabs when on high volume).

    • I've used the 2020A amps in a few cabs with decent results, it's small, cheap, easy to work with.

      I feel like there is probably a better audio amp option out there but I haven't found one.

      There seems to be either super cheap Chinese amps designed for small form factor and low power consumption, or super expensive audiophile amps that require a fusion reactor to run and a server rack to mount to with almost no options in between.

      My plan for the Vewlix was maybe retrofitting a Net City Amp in there since I have an extra kicking around.

      +1 for this

      I'll try changing out the input cable and see if that helps.
      If you have one, you could try using a home stereo receiver to test with, simply to rule out the amp in your cab or the speakers.

      I’ve used this amp in my diy cab with great results

      It’s pretty overkill, but I found an open box version for half the price at the time and couldn’t pass it up.
    • So I think I found a solution for this ( at least in my case. )

      Like I mentioned in my original post I mainly use my diamonds with a TypeX2. The other day I got curious as I only seem to have this problem with a few particular games on the X2. With a Naomi or RingWide I never have any audio problems. So I decided to hook up some head phones and see if I could isolate the issue to the cab or the X2. To my surprise I heard the same crackling through my headphones as I do the speakers in the Vewlix.

      Using my phone, I then decided to play some music from the game's OST through the vewlix and didnt have any problems.

      At this point I was sold on the problem being isolated to the TypeX2. I ended up trying a cheap PCI sound card in the X2 but it didnt solve the problem. I then decided since I was at it, I would try to update the SoundMax driver for the on board audio of the X2. The driver Taito ships with their images is v5.1 and the latest I could find online was v6.1. So I updated the driver, reset the audio levels to defaults, and fired up my test game. Boom! no more crackling. I played the game for a good 30 minutes just to be sure.

      I then decided to reimage my drive back to the factory image, and test the game again. Within the first minute I noticed the crackling audio was back. So I updated the driver again and got nothing but perfect audio.

      TL;DR: The X2 audio driver is old and needs to be updated.

      I plan to continue testing with the updated driver, and If I dont have any problems I'll be including it with the next version of my multi.
