New Motherboard: ASUS Z97-A (and Ubuntu)

My old desktop was seeing random drive errors on multiple drives, including a drive I only got a few months ago. And since my motherboard was about 5 years old, I decided it was time to replace it.

I asked the KWLUG mailing list if they had any advice on picking motherboards. The consensus seems to be pretty much “it’s still a crapshoot.” But I bit the bullet and reported back:

I bought a motherboard! An ASUS Z97-A

Mostly because I wanted Intel integrated graphics and I’ve got 3 monitors it needs to drive. And I was hoping the mSATA SSD card I got to replace the one in my Dell Mini 9 (that didn’t work) would fit in the m.2 slot. It doesn’t. Oh well.

I wanted to get it all set up while I was off for Canada Day. Except Canada Computers didn’t have any of my preferred CPU options. So I’ll be waiting for that to come in via NewEgg.

I gave myself a budget of about $500 for mobo, CPU and RAM and I’ll end up going over a little bit (mostly tax and shipping), and tried to build the best machine I could for that.

One of the things I did this time that I hadn’t done before was spec out a desktop machine at System76 and used that as a starting point. System76 is more explicit about things like chipsets for desktops than Zareason is. Which would be great, except they’re using the older H87 chipsets.

…Like the latest Ars System Guide Hot Rod But that’s over 6 months old now. And >they’re balancing their budget against having to buy a graphics card, which I don’t want to do.

I still have some unanswered questions about the Z97 chipset. It’s only been out for about a month. So who knows?

My laptop has mostly been my desktop for the last few years. But I want to knock that off because I’ve been developing back and neck problems. My desktop layout is okay ergonomically, at least better than anything I have for the laptop (including and especially my easy chair with a lapdesk, which is comfy, but kind of horrible on the neck). One of the things that’s holding me back is my desktop is 5 years old and was built cheap because I was mostly using it as a server by that point. I really want to make it something I want to use over the laptop (which is a very nice laptop). Which is why I ended up going somewhat upper-mid range.

That’s one of the nice things about building from parts, despite the lack of useful information: This is the 3rd motherboard I’ve put in this case. I replaced the PSU once a couple years ago so it’s quite sufficient to handle the new stuff. I’m keeping my old harddrives. I could keep the graphics card. I’ll need to buy an adapter for the DVD burner (and I’ve yet to decide if I’m going to do that, or buy a new SATA one or just go without). And I can keep my (frankly pretty awesome) monitors. So $500 gets me a kick-ass whole new machine.

Anyway, long story short, I still have a lot of questions about whether this was the best purchase, but I’m hopeful it’s a good one.

Aside: is Canada Computers really the only store in town that keeps desktop CPUs in stock anymore? I couldn’t get into the UW Tech Shop, but since they’re mostly iPads and crap now, I’m not optimistic. Computer XS doesn’t (at least the Waterloo one). Future Shop and Best Buy don’t. I even went into Neutron for the first time in over 15 years. Nope. Nobody.

It… didn’t go as well as I’d hoped:

So, anyway, I got the motherboard, CPU and put it all in my old case.

I booted up and all three monitors came up without any fuss, which has never happened for me. Awesome! This is great!

Then I tried to play game.

Apparently the current snd_intel_hda ALSA drivers don’t like H97 and Z97 chipsets. The sound was staticky, crackly and distorted.

I’ve spent more than a few hours over the last week hunting around for a fix. I installed Windows on a spare harddrive to make sure it wasn’t a hardware problem (for which I needed to spend the $20 to get a new SATA DVD drive so I could run the Windows driver disk to actually get actual video, networking and sound support :P). And I found this thing on the Arch WIki which, while not fixing the problem, did actually make it worse, leading me to conclude there was some sort of sound driver/pulseaudio problem.

Top tip: when trying to sort out sound driver problems for specific hardware the best thing to do is search for the hardware product id (in my case “8ca0”). That’s how I found this:

Hurray! The workaround works great and now I’m back in business!

So I got burned by going with the bleeding edge, and I should know better. But, even though the information isn’t widely diseminated yet, there is a fix. And a workaround. I’m sure Ubuntu 14.10 will have no problem with it. It’s not as bad as the bleeding edge was years ago. If the fix was easier to find (and I’m going to work on that), it was easier getting going with Ubuntu than it was with Windows.
