hardware, mutlichannel sound, ardour 5, ubuntu studio 17.04

I would greatly appreciate some advice on hardware for relatively hi-fi multichannel audio on ubuntu studio

I’m running ubuntu studio 17.04 on a thinkpad w520. I use Ardour 5 to write electroacoustic music & would like to move from working in stereo to writing pieces for a 4 speaker (& eventually 8 speaker) home studio setup.

I’ve heard a lot of people recommending hdmi but my thinkpad has no hdmi port so it seems like an external usb soundcard is my best option.

here’s my soundcard information that i got from running this command in terminal: lspci -v | grep -i audio

00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) Subsystem: Lenovo 6 Series/C200 Series Chipset Family High Definition Audio Controller

I’m posting here because I feel lost about which usb soundcard to get & also because I wanted to touch base to check if there are other better options than a usb soundcard for my current setup.

Thanks so much for your help!

Cannot get xsane to detect my Lexmark CX310dn mfp Scanner on Ubuntu 17.04

I have a Lexmark CX310dn mfp scanner attached over a network. Printing works fine, and I can connect to the printer using http.

I am running xsane 0.999 and I have checked the net.conf file, and saned.conf file to ensure they include the ip address of the printer/ scanner.

If I run sane-find-scanner, it doesn’t seem to check network scanners, and so tells me it isn’t attached as a SCSI or USB scanner.

Running scanimage -L gives the same result.

If I run the GUI xsane, it ponders, then tells me no scanners can be found, and all I can do is exit.

Any ideas as to how to get it to work would be appreciated. With no apparent debug, I am struggling!

Many thanks,

Installation of Teamviewer on Ubuntu 17.04 does not work (32-Bit machine)

I installed Ubuntu 17.04 on my 32-Bit notebook (previously used a WinXP-machine).
The notebook is a 32-Bit machine with 3GB RAM. Installtion of Ubuntu 17.04 worked fine.
I then tried to install Teamviewer (downloaded file teamviewer_14.1.18533_i386.deb), but constantly failed. During – incomplete – installation of Teamviewer I received messages about missing files/packages like


I had to remove Teamviewer from my system.
I am a rather unexperienced Ubuntu-user and wonder if someone can help me out with a description of steps to walk through when installing Teamviewer, especially how to install a .deb-file including all dependancies which might be necessary.

Thanks for your support. Best regards Michael

EXT4-fs error after Ubuntu 17.04 upgrade on Patriot burst drive

I saw some solutions to the Samsung drive but nothing for this one . I tried installing their utility:

sudo nvme list [sudo] password for user:  Node             SN                   Model                                    Namespace Usage                      Format           FW Rev   ---------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- -------- 

nothing shows up for my drive.
