Not debian but pretty thorough on mouse options in semi-current content.

Re: HP Chromebook 14 and crouton

You can change that tap to click behavior. I used to add mousedev.tap_time=0 to disable it BITD. But the newer kernels have differing names for that stuff now. And various tpconfig and other psmouse type module stuff to configure that stuff. Probably handled in udev rules these days ala /lib/udev/*....

Re: Raspberry Pi and music production

There's a phone app where the touch screen is a drumset and you finger drum. I have no ideal what it is, but the drummer in a band I play in uses it for rehearsals and brings out the set for gigs. If you could convert microphone events into midi events your could route them with qmidiroute to soft s...

Re: midi/jack issue

For me when I do that, the qjackctl connect screen shows the new device automagically. And the output of aconnect -l will change.

What does dmesg say when you toggle the on/off of the device? Perhaps it's looking for a driver and yours is not finding one.

Re: Building your own real-time kernel

Tried make localmodconfig and it reduced the outcoming linux-image package with about two thirds. Definitely a keeper! Be cautious when using that. It removes a lot of modules. Like every filesystem or device that is not currently in use on the local machine. For example iso9660 support, or loopbac...

Re: which laptop

Unless you do a lot of video encoding or 3D modeling, you probably wont notice much between cpu speeds. Amount of RAM and number of cpus seem to do more these days. A larger screen is always nice, your eyes probably don't get better with age. And other perks like power usage or battery life for the ...

Re: ALSA and USB interfaces: limited use?

It might be true if your only USB connection point is USB 1.1. But most of those computers are end of life (in theory). There are still a few usb 1.1 devices being used, but I think they go up to 48kHz and 2 in 2 out. The USB 2.x audio specification is younger than my current desktop which is 64 bit...

Re: How to send system sounds to fw card?

The simplest way is to reindex the drivers so the fw card is card 0 aka the default. You can have an .asoundrc with defaults.pcm.card # where # is the card number in /proc/asound/cards. If pulseaudio is your main sound configuration you can select it there with pavucontrol. You can also run pulseaud...

Re: the midi branch

- I checked the memory with memtest. Everything seems ok. That would have been my guess. You might run conky with a config to show RAM usage. And notice if there's anything happening there at the point of failure. And if it's consistent. Check for motherboard firmware updates? The compile error see...

Re: Jack xrun every 1.5-2 seconds. What am I missing?

If you're running pulseaudio over jack, it tends to play nicer at 48kHz. CPU frequency scaling can be a bit quirky. AFAIK it still throttles down (some) under the performance governor. So you might hard set the min and max values to the same value to prevent that when doing latency sensitive stuff. ...

Re: Any recommended PCIe audio card?

What's the vender:device from "lspci -n" for the device. So I can examine the alsa code base. Sometimes drivers contain assembly code which is platform specific, and that could be an issue, if it exists for that card. When it does exist, it normally uses the device ID to trigger that secti...

Re: My USB audio interface recently started failing to be fo

It might be more generic to call it hw:0,0 (playback), versus hw:0,1 (capture?). aka device 0 subdevice 0. Card specific names can be hit or miss. K6 or k6, or whatever applies depending on distro / package mood of the week. No real suggestions, just noting that that log entry doesn't really conform...

Re: Help with a inexpensive usb bass interface

Behringer Guitar Link UCG102 USB Interface --- seems to work for most folks at kernel 2.6.34+

I'm not sure if that was the one you were looking at using. USB 1.1 so probably 48kHz and 16bit for best sampling rates.

Re: Internet connection with KXStudio

Sounds more like DNS. You could use 8.8.8.8 which is googles name resolver. In the old days the /etc/resolv.conf file contained the line "nameserver 8.8.8.8". There are new-ish things that don't use or displace the /etc/resolv.conf file. Which can be distro specific. And normally ISPs issu...
