Nah! My in depth hobby is creating simple unusual electronics projects that create basic measuring devices for testing electronics in general and controlled by SW.

As quoted on another thread I am working on a basic Audio Function Generator all in pure POSIX shell scripting:
Sine, Square, Triangle, Sawtooth+, Sawtooth-, Pulse+, Pulse-, Noise and if possible Arbitrary from around 30Hz to 20KHz. It assumes that most sound systems can sample at 192000 sps maximum and 2000 sps minimum.
Obviously centred around this MBP, but includes ALSA - Linux and /dev/dsp for a limited CygWin version.
The waveforms generated will be pure ascii from character 32, (space), and character 126, (tilde).

But yes I am willing to pull out some background tracks if need be...

NAME
alsaconf - configuration tool for the Advanced Linux Sound Architecture SYNOPSIS
alsaconf [options] DESCRIPTION
This manual page documents briefly the alsaconf command. This manual page was written for the Debian distribution because the original program does not have a manual page. Alsaconf is a simple shell script which tries to detect the sound cards on your system and writes a suitable configuration file for ALSA. It will try to guess what GNU/Linux distribution you're running, and will act accordingly to the standards of that distribution, if spe- cific support is available. Alsaconf will write a module-init-tools (or modutils) snippet which can be then used by module-init-tools (or modutils) to load the correct parameters for your sound card. OPTIONS
Alsaconf accepts the following options: -c, --config file Specify the module config file. As default, alsaconf probes the available config file automatically. -d, --devmode mode Set the device mode for the ALSA devices (default = 0666). This option is obsolete in the recent ALSA version. -g, --gid gid Set the gid for the ALSA devices (default = 0). This option is obsolete in the recent ALSA version. -h, --help Displays this help text. -L, --log file Logging on the given file. The log is appended to the file. This option is for debugging purpose only. -l, --legacy Check only for legacy non-isapnp cards. -m, --modinfo Read module descriptions instead of reading a card database. -P, --listprobe List the supported legacy card modules. -p, --probe card-name Probe a legacy non-isapnp card and print module options. -r, --strict Set strict device mode (equiv. with -g 17 -d 0660). This option is obsolete in the recent ALSA version. -s, --sound-wav-file Use the specified wav file as a test sound. -u, --uid uid Set the uid for the ALSA devices (default = 0). This option is obsolete in the recent ALSA version. DEBIAN SPECIFIC
In Debian, the default gid of the device files is 29 (corresponding to the audio group) and the default device mode is 0660. For the ALSA base package, see also /usr/share/doc/alsa-base/ SEE ALSO
