Ubuntu audio issues

If you faced problems with the audio on your just installed Ubuntu, this is the simplest and quickest fix that I can find online.

With all due credit to those who found the solution first, here it is

1. Edit the Alsa config file

sudo vi /etc/modprobe.d/alsa-base.conf

2. Add at the end of the file the following line

options snd-hda-intel model=thinkpad

3. Restart the sound card

sudo /sbin/alsa force-reload

4. If your issue is still not solved, try changing the value for Step 2 to to something else other than 'thinkpad'. Refer to the list below.

Installing OMSA on Citrix XenServer

Latest version of OMSA differs from previous versions.

Instead of the server hosting a web service on port 1311, OMSA now operates by a client-server basis, in which you will use a remote management system web service instead to access the management service on the XenServer. In other words, you will need to configure the server as well as a client.

Below details the installation steps and how to remote manage your server.

1. Download the ISO file v7.3 for XenServer here



# wget http://downloads.dell.com/FOLDER01557095M/1/OM-SrvAdmin-Dell-Web-LX-7.3.0-357_A00.XenServer62.iso
2. Install OMSA
# xe-install-supplemental-pack OM-SrvAdmin-Dell-Web-LX-7.3.0-357_A00.XenServer62.iso
3. Post installation configuration
# cd /opt/dell/srvadmin/etc 
#./autoconf_cim_component.sh -p 5986
# service iptables save
# /etc/init.d/openwsmand restart
# /etc/init.d/sfcb restart
# iptables -I RH-Firewall-1-INPUT -p tcp --destination-port 5986 -j ACCEPT


4.Start the OMSA service
# cd /opt/dell/srvadmin/sbin
# ./srvadmin-services.sh start
Starting Systems Management Device Drivers:
Starting dell_rbu:[ OK ]
Starting ipmi driver: Already started[ OK ]
Starting Systems Management Data Engine:
Starting dsm_sa_datamgrd: [ OK ]
Starting dsm_sa_eventmgrd: [ OK ]
Starting dsm_sa_snmpd: [ OK ]
Starting DSM SA Shared Services: [ OK ]
5. Download another version of OMSA for your remote management system (the client) eg if you are using Windows, then download the Windows version here and install OMSA as per default

6. Open up a browser and type in the address as below.

https://client-system-ip:1311
If you are using your own system to access, then you can type https://localhost:1311

7. On the Managed System Login screen, type the credentials of the XenServer system you want to access, 
and then click Submit.

– Hostname / IP address: Hostname or IP address of the XenServer in the format 'Hostname:5986', or 'IP address:5986', as shown below.

Note: Tick on 'Ignore certificate warnings'
