I went back and tried the AES connection to see if there was any difference. There was a difference. Instead of a total dropout of audio, it crackled and popped. I raised a ticket with Line 6 and they again re-iterated that it was a problem they are aware of and as yet there is no timeframe for a fix, with no workaround. I was contacted shortly after, to be told to try firmware 2.30, which was released yesterday. Well, I've downloaded 2.30 and installed it. Unfortunately it made no difference.
I didn't buy the Helix specifically to use the SPDIF or AES connections, I bought it because I needed to get excited and inspired about playing guitar again and the HD500X wasn't doing that for me. I'm a composer more than a player so as long as I have a decent signal into my DAW for recording, I am happy. I don't really want to disconnect my audio interface and use the USB on the Helix so I guess my only alternative now is to use the line out connections. This is where I wish I had a patchbay but I can manage. This doesn't detract from the fact that my unit is faulty straight out of the box, firmware issue or not.
I'm upset and frustrated because from a non-professional standpoint (although I am trying to become professional), I have made a huge investment in Line 6 equipment (huge for someone who isn't making a living yet). First, I purchased a brand new JTV-89 that was virtually unplayable (suffered from fret buzz at various places on the board) until I paid extra to have it professionally setup and the model actuater switch still doesn't work because the shaft is too short (yes I saw the mod where you add a piece of folded paper into the know but come on, line 6 is a professional company); an HD500X, which to be fair spent more of it's time off than on only because it didn't inspire me tonally for recording; and now after taking a loan and spending more money than I ever have on a piece of equipment that everyone is raving about, to find that it doesn't work the way it was intended straight out of the box, well. My next purchase was to be an L2T or L2M, but how can I trust that this is the best option for me now? Getting inspired isn't just about the tone, it's about the after service too. The wasted hours when you first find there is a problem and search for a solution is kinda soul destroying. If you feel a company has let you down, does that not deflate you somewhat? Line 6 have been in the business for quite a few years now so you would think they would have a little more professionalism by now, especially as Yamaha are part of the picture.
Taking it back to previous comments where someone said they use the SPDIF and they don't have an issue with dropout; another said they got a replacement and haven't had an issue with the new unit, that suggests that not all the units are affected by this problem. So how then can it be a firmware issue? If there is no timeframe for a fix, that says to me that it isn't a priority. That could be because not enough people have raised it as an issue, maybe because they don't use it so don't really care or are unaware. It could also be that they are concentrating on getting things ready for another launch with shows coming up in the new year. Numbers would tell the real story but people only report what is broken and if they don't use that connection (or they do and it is fine), then we won't have a true indication as to how many units are affected by this issue. I'm still yet to be convinced that this is a firmware issue.
