NAME

smmixer - get/set Linux soundcard packet radio modem driver mixer

SYNOPSIS

smmixer[-i device][ params ]

DESCRIPTION

smmixerdisplays and/or sets the input source and input and output levels of asoundcard modem port.

OPTIONS

smmixeraccepts the following option:

-i: Thedeviceargument specifies the soundcard modem device which should be configured orinterrogated. It will usually have the following form:sm[0-3].

PARAMETERS

TheAD1848 (WSS)mixer accepts the following parameters:

ol=val: sets the level of the left output to the specified value. Legal values are from-100..0dB.
or=val: sets the level of the right output to the specified value. Legal values are from-100..0dB.
o=val: sets the level of both outputs to the specified value. Legal values are from-100..0dB.
il=val: sets the level of the left input to the specified value. Legal values are from0..43dB.
ir=val: sets the level of the right input to the specified value. Legal values are from0..43dB.
i=val: sets the level of both inputs to the specified value. Legal values are from0..43dB.
sl=val: sets the source of the left input to the specified value. Legal values areline, aux1, micordac.
sr=val: sets the source of the right input to the specified value. Legal values areline, aux1, micordac.
s=val: sets the source of both inputs to the specified value. Legal values areline, aux1, micordac.
TheCT1335 (SB2.x)mixer accepts the following parameter:
o=val: sets the output level to the specified value. Legal values are from -46..0dB.
TheCT1345 (SBPro)mixer accepts the following parameters:
ol=val: sets the level of the left output to the specified value. Legal values are from-46..0dB.
or=val: sets the level of the right output to the specified value. Legal values are from-46..0dB.
o=val: sets the level of both outputs to the specified value. Legal values are from-46..0dB.
s=val: sets the input source to the specified value. Legal values aremic, cdorline.
TheCT1745 (SB16, SB32 AWE)mixer accepts the following parameters:
ol=val: sets the level of the left output to the specified value. Legal values are from-62..18dB.
or=val: sets the level of the right output to the specified value. Legal values are from-62..18dB.
o=val: sets the level of both outputs to the specified value. Legal values are from-62..18dB.
il=val: sets the level of the left input to the specified value. Legal values are from-62..18dB.
ir=val: sets the level of the right input to the specified value. Legal values are from-62..18dB.
i=val: sets the level of both inputs to the specified value. Legal values are from-62..18dB.
s=val: enables the specified value as a source. Legal values areline, line.l, line.r, midi, midi.l, midi.r, cd, cd.l, cd.rormic.

CONSIDERATIONS

It is important that the audio levels of your radio match those of thesoundcard. To help achieve this, use thesmdiagutility.

This utility can only be used after the interface is started up, i.e. afterifconfig sm? up.

The sound driver and the soundcard modem driver are mutually exclusive, i.e. theycannot both access the same soundcard at the same time. Even worse, the sound driverreserves the soundcard as soon as it gets loaded. The souncard modem driver howeverreserves the card only when the interface is started, i.e. during ifconfig if up.

9600 baud may not currently work on SoundBlaster cards with DSP revision 4.x, i.e.SB16 and SB32 AWE. This is because they seem to not be fully backwards compatible.
