(custom kernel is there to support PPS for my GPS clock)
Attempting to add a generic card that claims to have a Envy24DT chipset
in it; it identifies and loads under the snd_envy24ht driver as:
pci6: <multimedia, audio> at device 0.0 (no driver attached)
pcm0: <Envy24HT audio (Generic)> port 0xcc00-0xcc1f,0xc880-0xc8ff irq 16
at device 0.0 on pci6
pcm0: [GIANT-LOCKED]
pcm0: system configuration
SubVendorID: 0x1412, SubDeviceID: 0x2403
XIN2 Clock Source: 24.576MHz(96kHz*256)
MPU-401 UART(s) #: not implemented
ADC #: 1 and SPDIF receiver connected
DAC #: 4
Multi-track converter type: AC'97(SDATA_OUT:packed)
S/PDIF(IN/OUT): 1/1 ID# 0x00
GPIO(mask/dir/state): 0xff/0xff/0xff
cat /dev/sndstat returns:
[root@NewFS /boot/kernel]# cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <Envy24HT audio (Generic)> at io 0xcc00:32,0xc880:128 irq 16
(1p:1v/5r:1v) default
So it appears it did attach properly.
But.... an attempt to output something to /dev/dsp0 looks like it is,
but nothing happens (no sound)
ie:
# sysctl -w hw.snd.verbose=2
# mpg123 some-mp3-file &
# sndstat | more

Says its running, and mpg123 has attached to it -- but no output.
Mixer says the volume is on:
[root@NewFS /boot/kernel]# mixer
Mixer vol is currently set to 75:75
Mixer treble is currently set to 0:0
Mixer synth is currently set to 0:0
Mixer pcm is currently set to 75:75
Mixer speaker is currently set to 0:0
Mixer line is currently set to 75:75
Mixer mic is currently set to 0:0
Mixer cd is currently set to 0:0
Mixer mix is currently set to 0:0
Recording source: mic
Ideas for further troubleshooting?
I don't know the internals of the sound code, but as there are no other
replies yet. Did you test the obvious things? Speakers connected
correctly? Does mpg123 work well? Try another player also.
