The application may have a configuration setting that specifies |
| 10 |
the audio device to use. This would be found in some application |
| 11 |
menu entry or in some application configuration file. |
| 12 |
|

You may want to try specifying a default PCM entry in your |
| 14 |
alsa asoundrc configuration file. Information on that is |
| 15 |
found here: |

Also, as Duncan suggested, you may want to disable the ATI HDMI |
| 20 |
entirely. There could be several methods to accomplish this, but |
| 21 |
I use the following procedure. |
| 22 |
|
| 23 |
Find the ATI HDMI pci id with: |
| 24 |
|
| 25 |
lspci | grep -i audio |
| 26 |
|
| 27 |
The ID is the leftmost field, for example, 01:00.1. |
| 28 |
|
| 29 |
Now, find the correct directory in the /sys tree that corresponds |
| 30 |
to this pci id: |
| 31 |
|
| 32 |
find /sys/devices -name *01:00.1 |
| 33 |
|
| 34 |
This will give an output similar to this: |
| 35 |
|
| 36 |
/sys/devices/pci0000:00/0000:00:03.0/0000:01:00.1 |
| 37 |
|
| 38 |
Now, add add this to the appropriate boot script: |
| 39 |
|
| 40 |
echo 1 > /sys/devices/pci0000\:00/0000\:00\:03.0/0000\:01\:00.1/remove |
| 41 |
|
| 42 |
(where the ":" character is escaped with "/") |
| 43 |
|
| 44 |
At each boot the ATI HDMI audio will be disabled. |
| 45 |
|
| 46 |
Let us know if this works for you. |
