Re: [Alsa-user] Need optic out for VIA VT1708 on pico-itx
I'm concerned because http://alsa.opensrc.org/DigitalOut example shows 'cat /proc/asound/devices' with a unique hw:x,y for the digital audio playback device, and my output shows: 16: [ 0- 0]: digital audio playback 17: [ 0- 1]: digital audio playback and neither of these work: aplay -D plughw:0,0 Track01.wav aplay -D hw:0,0 Track01.wav aplay -D plughw:0,1 Track01.wav aplay -D hw:0,1 Track01.wav When I get it right should I be able to see a red light coming out of the optic audio port?

Re: [Alsa-user] Select a Virtual device
Hi!
These are just ideas, I really don't know for sure. But maybe it helps...
Try wrapping your devices in plug-devices like this:
pcm.plug_player {
type plug
slave { pcm audio_player
}
Or try to remove the ctl-devices. With aplay and other good alsa-programs
they shouldn't be necessary. At least it says so on the alsa wiki somewhere.
Or try writing the ctl description like this:
ctl.audio_player {
type hw
card 0
}
Another option is to use the jack-plugin and start jack. So you could use
the jack-server to interconnect your apps.
pcm.myjack
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}
I don't know if you can open this port multiple times at once. If not just
define a second jack device. To avoid problems, wrap them in plug devices,
as shown above with your audio_player device.
HTH.
Kindest regards

They are. I compiled both. The size of the respective parameter structures is encoded in the IOCTL numbers. Since it is the snd_mixer_load() function that failed, earlier ioctl calls succeeded, so it's very likely that the reason that SNDRV_CTL_IOCTL_ELEM_READ is unknown is that the size of struct snd_ctl_elem_value is different. Please put a printf(struct size: %u\n, sizeof(struct snd_ctl_elem_value)); (or printk) into both alsamixer and some kernel code (for example, snd_ctl_ioctl() in core/control.c).

[Alsa-user] Using dmix/dsnoop/dshare to access individual channels of multichannel codec
I am using a 4-input, 8-output codec (AD1938) in an application similar to a live sound mixing board, where a combination of the input signals get mixed for each output. I can mix four inputs to four outputs with a command like: arecord --file-type raw --channels=4 --format=S32_LE --rate=16000 \ | crosspoint \ | aplay --file-type raw --channels=4 --format=S32_LE --rate=16000 where crosspoint is a simple program that reads from stdin, does some mixing, and outputs to stdout. My next step is to play and record wave files from the various channels, while the crosspoint is running. For example, I might need to play message1.wav to channel 2 and message2.wav to channel 3 while recording channel 1 to message3.wav. I am looking for advice about the best way to accomplish that. It seems like it should be possible using a combination of dmix, snoop, and dshare, as follows: - Use dsnoop to split the 4-channel input to the crosspoint and another virtual sound input, call it A. - Use dshare to split A into four mono sources. Then can use arecord normally to capture wave files. - Use dmix and possibly dshare to similarly let the crosspoint continue to use the multi-channel output while also providing a mono sound device for each channel that I can use with aplay. Am I on the right track, or would I be better off adding functionality to the crosspoint application to read and write wave files? Thanks for any suggestions.

Re: [Alsa-user] Need optic out for VIA VT1708 on pico-itx
I think the audio card is working. The problem is in the way the motherboard and case are wired. The front digital audio port traces to SPDIF_IN (pin 17 of the 18 pin Front Audio Pin Connector), which means this can only accept Optic-Digital-IN. The only SPDIF_OUT appears on pin 57 of the 80 pin Multimedia Connector (connector only ~20mm long), which is wried to nothing. I need to find a mate for the 80 pin Multimedia Connector and solder it to an fiber optic transmitter to get Optic-Digital-OUT. I'll beg Via for help in finding a plug to fit that connector.
