<div dir="ltr">Firstly, sincere thanks for all the excellent replies, and for helping clarify my thinking on the USB-C form factor versus the USB protocol itself - great stuff, and much appreciated! I looked into USB interfaces a great many years ago, and seem to recall determining they weren't sufficient at that time. I'm hoping that's changed (and it sounds like it has).<div><br></div><div>I didn't do a good job of explaining what I'm hoping to accomplish: I've been using Ardour for nearly a decade now via my M-Audio FireWire Solo, often directly recording guitars, but also mic-ing cabs, recording vocals, etc. I'd like to try using Ardour on my Pixelbook, and while there are various hacks to get Linux on a Pixelbook (like Crouton), I'm awaiting the official release (Crostini - coming with Chrome OS v69 in a couple of weeks, as I understand it). Since the Pixelbook doesn't have a FireWire port (and FireWire --> USB doesn't seem to be a thing), I need an audio interface. The Pixelbook only has USB-C, so that's where my search began - with the plug. My latency on my Linux box as reported by JACK in settings is 2.7ms, which is great, and very important when playing guitar against a recorded track while hearing a bit of the live amp (typically a Marshall that's way, way too loud...in a good way!). I'm hoping to avoid any major latency increases (while guessing that the containers used by Crostini may themselves introduce latency - this may yet prove to be a failed experiment).</div><div><br></div><div>Also hoping to get feedback on good USB interfaces in terms of the DAC (appreciate the feedback on the RME HDSPe AIO, Ralf, but looks to me like that's a PCI card, which won't work with a Pixelbook - or am I looking at the wrong model?).</div><div><br></div><div>>...while Linux apps are running on the Pixelbook in Chrome OS via crostini, sound support does not exist for them as of yet </div><div><br></div><div>Thanks - I wasn't aware that Crostini lacks sound support thus far - I see from the Chromium bug report that it's scheduled for V70, so looks like I'll have to wait a bit longer (which gives me some more time to research interfaces and decide if this is a good idea!).</div><div><br></div><div>>Perhaps a pixelbook _is_ like a "real" laptop.</div><div><br></div><div>Yes, it is: Intel Kaby Lake i5, 8GB RAM, 128GB SSD all inside a pretty amazing package. It's not a $200 Chromebook incapable of doing anything else - it's a full-on laptop, with perhaps the best keyboard I've ever used. I'll stop gushing here...</div><div><br></div><div><div>>Not really much benefit from 3 vs 2.</div><div><br></div><div>Good to know - thank you.</div><div><br></div><div>Interesting discussion re: power supply - I'm hoping not to require one and am guessing (read: hoping) the Pixelbook has enough juice - I currently power a secondary monitor via a USB-C connection only.</div><div><br></div><div>Thanks again for all the feedback and discussion - as always, learning tons from this mailing list.</div><div><div dir="ltr" class="gmail-m_5402069503534628771gmail_signature"><br>Kindest regards,<br><br>Martin<br></div></div><br></div><br><div class="gmail_quote"><div dir="ltr">On Wed, 22 Aug 2018 at 15:09, Paul Davis <<a href="mailto:paul@linuxaudiosystems.com" target="_blank">paul@linuxaudiosystems.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div style="font-family:arial,helvetica,sans-serif"><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Aug 22, 2018 at 2:55 PM, Martin Lynch <span dir="ltr"><<a href="mailto:martin.lynch.toronto@gmail.com" target="_blank">martin.lynch.toronto@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div dir="auto">Hi,</div><div dir="auto"><br></div><div dir="auto">Wondering if anyone is using, and can recommend, a USB C guitar interface? </div><div dir="auto"><br></div><div dir="auto">I presently use an M-Audio FireWire Solo, however with Linux soon coming to my Pixelbook (which has 2 USB C ports only), I thought I'd try running Ardour on that.

Just get a regular USB based audio interface, and add whatever electronics you need between your guitar and its input ports. </div><br><div style="font-family:arial,helvetica,sans-serif">Most USB interfaces these days Just Work on Linux, thanks to the requirement that they also Just Work on iPads, where manufacturers cannot provide device drivers but must rely (as effectively they do on Linux) on the common USB audio driver that comes with the system. </div><br></div></div></div></div>
