Text to speech through a USB sound card

[G4UFS]

Hi,

I have installed a USB sound card and all is well using MPD but I need to use a text to speech engine that will play through the new USB card.

I have tried, Espeak, Festival, Flite and Google but none of them seem to be configurable to work with the add on sound card.

I believe that it is the sound card device number which is the root cause since configuring MPD to use h1,0 makes it play through it - My USB sound card number shows as "card 1" when I run aplay -l

I am happy to disable the onboard Pi sound card so if there were a way to either configure Espeak to use card 1 or configure the Pi so that the USB card is "0" I think it would all work.

Any ideas?

Search for 'USB audio' on this forum to find instructions how to configure the new device to be the first one. Maybe that would help?

Thanks for the reply and I have searched the forum but I cannot seem to find anything about making the USB sound card the first device? Have I missed something?

Well, coming up with suitable search keywords is sometimes hard - mostly because there is too much waffle on the internet...

Cloudcentric pointed the relevant wiki section - the 'alsa-base.conf' bit there.

Thanks guys. Initially, I missed the top part of the page where it discusses making the card the first one to be detected. Oopps.

I will test this evening and see what I get

USB sound card must be fixed as hw 0,0 in " /etc/modprobe.d/alsa-base.conf " :

options snd-usb-audio index=0

And make the usb card as the default device in ” /etc/asound.conf ”
Just erase all and replace with this :

pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}

I had a similar problem with a USB card.
At first neither my USB attached mic or speakers worked.
Then I checked what devices I had using
$ aplay –l

The command the shows the RPI default card as 0 and the USB device as 1
So I put the following in my config file:

pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}

Note I have Card 1 not 0

After that aplay and a record worked fine through the USB device, but when I installed Espeak it stubbornly refused to find the USB device, gave errors and sent the output through the on-board sound output.

Does anyone know how to fix this, all the discussions I have found so far suggest card 0 might be hard coded into espeak.

Ignore my last post, just re-read the previous post and the bit about making the USB as device 0. Works great now with all the stuff as per the original post.
