I hope you did the "make uninstall" like I requested. Else nothing we try may work.
First, I would like you to do a test in run level 3, to ensure there is not a setting in your Desktop/Window manager that is causing this affect. Please reboot your PC to run level 3 (a text log in). You can do that by typing "3" (no quotes) in the grub menu when it appears. Your PC will boot to a text prompt. Log in as a regular user (and use regular user password). Then type (note this is case sensitive):
Code:
speaker-test -c2 -Ddefault -twav
Note you stop that sound application by pressing <CTRL><C>
You can reboot from this point by typing "su" (enter root password) followed by "shutdown -r now" [no quotes in both cases]
When you performed this sound test, do you still have the same echo? If there is no problem in run level 3, then the echo is a desktop setting that is causing the problem, and you need to investigate your desktop settings. If you still have the echo problem, then please go on to the next step.
Your hardware codec is a CX20549, which is the same as a Conexant 5045. The ALSA-Configuration.txt file notes the following:
Code:
Conexant 5045
******laptop-hpsense****Laptop with HP sense (old model laptop)
******laptop-micsense** Laptop with Mic sense (old model fujitsu)
******laptop-hpmicsense Laptop with HP and Mic senses
******benq********Benq R55E
That guidance relates to added content in the /etc/modprobe.d/sound file.
Please edit your /etc/modprobe.d/sound file, and change it to:
Code:
options snd-hda-intel enable=1 index=0 model=laptop-hpsense
# wRyD.ALuUqiQILF2:MCP51 High Definition Audio
alias snd-card-0 snd-hda-intel
Then in an xterm/konsole with root permissions restart your alsa with:
<span style="font-family:Courier New">dmesg > dmesg.txt</span> and search for sound/alsa errors in the newly created "dmesg.txt" file. DON'T POST the entire dmesg.txt file here. It is too long.
Good Luck!
