First off, thanks for mentioning it, lacking Linux experience i didn't know this command.

As it is, it didn't work. Here is what i did:

Code:
ifconfig wlan0 up
iwconfig wlan0 key s:<my-key>
iwconfig wlan0 essid <my-essid>
dhclient wlan0

All these commands proceeded without error, but there was still no wireless connection after that.

For sound, you could try the following in /etc/modprode.d/sound (or whatever filename is appropriate on fedora)
I found a file /etc/modprobe.d/alsa-base and modified it according to your suggestions. In fact it had a single line "options snd-hda-intel enable_msi=1" already in it.

Alas "update-modules" is not available on my system. I investigated and to my current information it is a tool solely used on S390 systems. If it is available on PC systems too where can i download it? Anyway, i rebooted, which should have the same effect but still no luck with the sound.

You can run a command line speaker test with
Code:
speaker-test -Dplug:front -c2 -l5 -twav

I ran this command but it hangs indefinitely:

Code:
[root@mysystem ~]# speaker-test -Dplug:front -c2 -l5 -twav

speaker-test 1.0.18

Playback device is plug:front
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 32 to 8192
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
 0 - Front Left

NAME
wicd-wired-settings.conf - controls Wicd's wireless network settings DESCRIPTION
This file contains configuration information for wireless interfaces in Wicd. This file is located at /etc/wicd/wireless-settings.conf SETTINGS
bssid = <BSSID_of_network> This value can be found using iwconfig(8). essid = <ESSID_of_network> This value can be found using iwconfig(8). hidden = <True|False> This option notes whether the network's ESSID is broadcast or not. channel = <integer_value> Valid channels are dependent upon country. This value can be found using iwconfig(8). mode = <Master|Ad-hoc> This value can be found using iwconfig(8). enctype = <encryption_template> This can take the value of any encryption template shown in /etc/wicd/encryption/templates/. encryption_method = WEP|WPA|WPA2> This value can be found using iwconfig(8). key = <plain_text_key> Be sure this file is readable only by root. automatic = <True|False> This option determines whether Wicd should automatically connect to this network. ip = <None|ip_address> Use this option if you have a static ip address for your system. netmask = <None|networkmask> This setting is only appropriate if a static ip address is configured above. broadcast = <None|broadcast_address> This setting is only appropriate if a static ip address is configured above. gateway = <None|gateway_address> This setting is only appropriate if a static ip address is configured above. use_static_dns = <True|False> True = use static DNS servers instead of accepting what the dhcp server supplies. use_global_dns = <True|False> True = use the global DNS servers provided in wicd-manager-settings.conf(5). This option is only appropriate if "use_static_dns = True" dns1 = <None|ip_address> Static DNS address if "use_static_dns = True" and "use_global_dns = False" dns2 = <None|ip_address> Static DNS address if "use_static_dns = True" and "use_global_dns = False" dns3 = <None|ip_address> Static DNS address if "use_static_dns = True" and "use_global_dns = False" use_settings_globally = <0|1> Wicd keeps track of whether to autoconnect to networks based on bssid. This ensures that you don't accidentally connect to another network that is not yours but happens to have the same essid - for example, there are a lot of commercial routers in use with "linksys" as the essid. 0 = Do not use settings globally 1 = Use settings globally beforescript = <None|arbitrary_script> This defines a script to run before Wicd brings up the connection. IMPORTANT - scripts should ONLY be writable by root and should be located in a directory that is writable by only root. afterscript = <None|arbitrary_script> This defines a script to run after Wicd brings up the connection. IMPORTANT - scripts should ONLY be writable by root and located in a directory that is writable by only root. predisconnectscript = <None|arbitrary_script> This defines a script to run before Wicd disconnects the interface. postdisconnectscript = <None|arbitrary_script> This defines a script to run after Wicd disconnects the interface. IMPORTANT - scripts should ONLY be writable by root and located in a directory that is writable by only root. OTHER
The "use_settings_globally" option determines how an individual network's configuration stanza starts. If the option is "0" (do not use settings globally), then the stanza's top line will be the bssid of the access point (in this format): [00:15:3E:87:D3:68] If the "option is set to "1" (use settings globally), then the first line of the stanza will be in this format: [essid:UA Public Wireless Network] SEE ALSO
