Hi guys! Hope you are doing great! Before doing an RMA, let me check with you to see if I'm missing something. I have just bought a Creative SB ZX card. Plugged it in and configured everything after a succesfull driver install. Tried my 5.1 audio sistem through Toslink with DDL and everything went fine. Then, I decided to try out my shure srh-440 with the external ACM. Plugged them in and the driver control panel recognized I plugged in headphones and tried them out. It would seem at first that audio was coming only from the left speaker. I fiddled around with settings, balance, etc. to no avail. I then tried to move the cables from the back of the soundcard... and nothing. Then tried moving the cable that was plugged to the ACM and found out that if I unplugged the cable just a bit, audio would come from both speakers, but predominantly from the left. I decided to ditch the ACM and plugged my headphones to the back panel directly and they worked flawlessly. It would seem that the ACM is bugged... but if it does provide sound from the left speaker, it isn't broken, is it? Has anyone had this or a similar issue? Is there any workaround? Any help would be appreciated. p.s I had an X-fi Titanium Fatal1ty Pro before this (still have it on my power) and I think that the surround options on 5.1 though Toslink were more complete. Also CMSS 3D is not available in this card, but SBX pro studio wich sucks... I'm thinking more about doing a refund than an RMA... Any thoughts on this?
