frequent crashes on ubuntu 18.04 #2

Hi there, I have followed the step described in the installation, (actually using the provided script) however, if I disconnect the USB interface and reconnect, I have a crash of the full system, I need to restart the computer.

If I try

arecord -f S24_3LE -r 48000 -c 2 test.wav I can record sounds though not sure if they come from the tascam or the internal mic.

my asound.conf looks like

pcm.USX2Y { type hw; card USX2Y; } ctl.USX2Y { type hw; card USX2Y; }

pcm.!default pcm.USX2Y ctl.!default ctl.USX2Y

So I decided to give a try to arecord -D hw:2,0 -f S24_3LE -r 48000 -c 2 test.wav since the tascam is listed as interface 2 and my intel as interface 1 (there is no 0)

As a result I could start recording. However pressing Ctrl-C to stop it again freezes the computer completely and I need to restart it.

The third attempt was to use audacity, once more, starting audacity just freezes the computer and I need to restart it

PS I can start Jackd on the tascam apparently, but when trying to record using system in Audacity I cannot record anything, the monitor seems to only work on one of the two channel (the left).

So, summarizing, I am unable to use my card on ubuntu 18.04, what am I doing wrong?

Thanks in advance

Hello. Sorry for the late response to your problem.

I suppose you fixed your problem one way or the other now. If not, and for the purpose of others I'll answer you nevertheless. And if so, I hope that you'll enlighten us. :P

I was facing this issue also a lot of times, using specific hardware. After switching to another desktop rig, and switching to arch I couldn't experience those kind of freezes anymore. I'm clueless as to why those freezes did occur, I once tried looking through systemlogs and finding a definitive answer, but I couldn't hunt it down. All I know is that it's common with this device.

It seems to be either some driver, or usb related thing - it being an old usb 1.1 device - others were pointing towards disabling kernel modules for USB higher than 1.1.

It still might be driver related - or maybe pulserelated? When disabling pulseaudio all together i think it helped reducing freezes, back on a debian based setup.

You might try to make space for a little partition and trying this route presented with an arch installation: https://wiki.archlinux.org/index.php/Professional_audio#Tascam_US-122

Wish you all the best. The Device, when working is a great interface.

Little sidefact: I tried to make this interface to work under Windows. Driver Support has been cancelled since Windows Vista afair - and i wasn't able to even get it recognized.
