First, check whether your sound card is recognized by Ubuntu. Ubuntu uses to control the sound card ALSA And constitutes the kernel modules (drivers) are available. ALSA is already installed, you must download and install the driver so no sound - how to do that in Windows is often used.
Code:
cat / proc / asound / cards
If Recognition works
A functioning detection for example, looks like this:
Code:
0 [CMI8738MC6]: CMI8738-MC6 - C-Media PCI CMI8738-MC6
C-Media PCI CMI8738-MC6 (model 55) at 0xD800, irq 19
1 [V8237]: VIA8237 - VIA 8237
VIA 8237 with AD1888 at 0xe000, irq 20
Here are two sound cards were detected by ALSA: a CMI card with the number "0" and the ALSA-called "CMI8738MC6", and a VIA card with the number "1" and the ALSA-called "V8237". If a card with the name "UART" are found, this provides an interface to MIDI dar. MIDI who says nothing that can ignore it. ALSA can also detect TV cards, of which one should not also be irritated.
Now Play
If ALSA has detected a card, so check if the sound system receiving data will:
Code:
aplay / usr / share / sounds / startup.wav
From Intrepid Ibex exists / usr / share / sounds / startup.wav not, you have to use a different wav file so, for example,
Code:
aplay / usr / share / sounds / alsa / Front_Center.wav
Here, the output should look something like this:
Code:
Play Wave '/ usr / share / sounds / startup.wav': Signed 16 bit Little Endian, Sampling Rate: 44100 Hz, stereo
This means that the file is played - whether you hear it or not. I got a little display quite different, so already the transfer of the file fails because of the sound system. More on that later.
