the first driver worked perfectly, but I was curious about the new driver I don't see a new driver on the support page. Description: Realtek ALC883 Audio Driver for Linux. File Size: 37.21 MBytes - update 2007/05/07 Download from: http://dlcdnet.asus.com/pub/ASUS/mb/socket775/P5K/Audio_L.rar Possible solutions: Restore from your last ...

If you installed the audio drivers, you most likely installed the ALSA package. When ALSA installs, it is set to "global Mute" and you have to open ALSA and take it off mute before your audio can be used. In a terminal type alsamixer if command not found, type sudo apt-get update sudo apt-get install alsa-utils and then alsamixer and take it off ...

If you haven't already, I suggest you install pavucontrol to give you a good view of what pulseaudio thinks is going on. In alsamixer, check and make sure that the right sound card is selected. I suggest you might try asking on the linuxmusicians forum, where the knowledge level of linux audio is pretty high.

Have you checked in sound settings that the sound is going to the right place? To get there, click on the speaker in the top bar, then on System Settings in the dropdown. Try choosing different devices under "play sound through". I find this is what causes this problem most of the time. Another possibility is that the sound is turned down too low. Try ...

Your alsamixer settings show that the Mic is muted. Open a terminal and issue the command: alsamixer Use the arrow keys to highlight "Mic" which will be red. Tap the M key and use the up and down arrow keys to adjust. (I would start at the midway point and adjust until I got the results I wanted).

A bit late in the day but I recently got similar static background noise issue with my laptop's internal microphone (same Realtek chipset I believe but solution should work for all soundcards). After looking around, there is indeed a way to reduce noise in realtime in pulseaudio using webrtc echo-cancel plugin (the default speex echo-cancel in Ubuntu/Mint ...

To route the IDJC output to the speakers, use a tool such as QjackCtl to make a connection from the IDJC output ports to the ALSA speaker ports:

I am not 100% sure I understand your problem, but my headphones stopped working all of a sudden, and the solution was to do the following two things: Reset user configuration (as described in the Troubleshooting section of https://wiki.ubuntu.com/PulseAudio); Make sure Independent HP is Disabled in alsamixer. To do that, just type alsamixer in a terminal, ...

I had the same problem for days (on a different laptop). The solution was to do the following two things: Reset user configuration (as described in the Troubleshooting section of https://wiki.ubuntu.com/PulseAudio). Make sure Independent HP is Disabled in alsamixer. To do that, just type alsamixer in a terminal, then choose your sound card (by pressing F6) ...

I added my user to the 'audio' group and after re-logging in, it was fixed. $ usermod -a -G audio myuser I noticed when aplay wasn't able to list devices as a user: myuser: # aplay -l aplay: device_list:268: no soundcards found... root: # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC892 ...

Ok. Finally fixed the problem. It appears openbox removes user acl from /dev/snd/*. Before I start openbox, if I run the following command, I see my username with "rw" permissions. $ sudo getfacl /dev/snd/* However, if I run the same command from openbox terminal, my username is not listed at all. Fortunately, group "audio" is listed in both cases with ...

I did eventually find the problem - the card was configured for 24-bit samples, but alsa was outputting 16-bit samples (hence the weirdness). So far, the only remedy was to boot windows, change the card to 16-bit, then reboot ubuntu. edit: well that works until the machine goes into standby, then the old problem is back. I give up. edit2: Eventually ...

Finally managed to set this permanently, I had to add the following command in the startup applications. pacmd set-card-profile 0 output:iec958-ac3-surround-51 To verify the name of you sound profile, run following command, u'll get all available profiled for ur sound card. pacmd info For some reason adding this default device in default.pa didn't work, ...

The 3rd log shows audio underuns in Pulseaudio due to high cpu load, so i would try to disable Pulseaudio to see if Alsa only is better : Run this 2 commands in terminal: echo autospawn=no > ~/.pulse/client.conf pulseaudio -k This will stop pulseaudio, then relaunch your software and test . You can set alsa layer volume with alsamixer in a terminal ...

(Re?)Install the "unity-control-center" package (this depends on the libcanberra-pulse as well), i.e. run sudo apt-get install unity-control-center in a terminal. This fixed it for me. :)
