NAME #
sv - S3 SonicVibes audio device
SYNOPSIS #
sv* at pci? audio* at sv?
DESCRIPTION #
The sv driver provides support for S3 SonicVibes (S3-617) chipset-based cards. Disabling the SRS 3-D spatial feature of the chip is recommended for higher quality audio. This can be done in software by issuing the following command:
$ mixerctl outputs.spatial=off
SEE ALSO #
HISTORY #
This driver is based on the eap(4) driver by Lennart Augustsson. The sv device driver first appeared in OpenBSD 2.6.
BUGS #
The “FM” DAC, wavetable synth, and MIDI port are not supported. Recording at a rate different from playback is supported by the chip but not the driver. The mixer does not allow control of reverb, digital loopback, or 3-D SRS features. The chip does not support exact record speeds (it seems) of 11025Hz, 22050Hz, and so on, used by Windows audio. Usually, the actual record is rate is around +/- 50Hz of the specified.
