Disabling the SRS 3-D spatial feature of the chip is 46recommended for higher quality audio. This can be done in software 47by issuing the 48.Bd -literal -offset indent 49mixerctl -w outputs.spatial=off 50 51.Ed 52command. 53.Pp 54.Sh SEE ALSO 55.Xr audio 4 , 56.Xr mixer 4 57.Sh HISTORY 58This driver is based on the 59.Xr eap 4 60driver by Lennart Augustsson. 61The 62.Nm 63device driver appeared in 64.Ox 2.6 . 65.Sh BUGS 66The "FM" DAC, wavetable synth, and MIDI port are not 67supported. Recording at a rate different from playback is supported by 68the chip but not the driver. The mixer does not allow control of reverb, 69digital loopback, or 3-D SRS features. The chip does not support exact 70record speeds (it seems) of 11025hz, 22050hz, and so on, used by 71Windows audio. Usually, the actual record is rate is around +/- 50hz of 72the specified. 73
