/* Maestro PCI sound card radio driver for Linux support
|
||||
* (c) 2000 A. Tlalka, atlka@pg.gda.pl
|
||||
* Notes on the hardware
|
||||
*
|
||||
* + Frequency control is done digitally
|
||||
* + No volume control - only mute/unmute - you have to use Aux line volume
|
||||
* control on Maestro card to set the volume
|
||||
* + Radio status (tuned/not_tuned and stereo/mono) is valid some time after
|
||||
* frequency setting (>100ms) and only when the radio is unmuted.
|
||||
* version 0.02
|
||||
* + io port is automatically detected - only the first radio is used
|
||||
* version 0.03
|
||||
* + thread access locking additions
|
||||
* version 0.04
|
||||
* + code improvements
|
||||
* + VIDEO_TUNER_LOW is permanent
