Accessing the sound system causes freezes of the system, so it is disabled for now.

Subject: [PATCH] Disable sound in kernel
|
|
|
|
Everytime the audio subsystem is accessed (such as via hwtest), the
|
|
device hangs. This causes problems as one cannot enter even simple DEs
|
|
like XFCE4 without freezes.
