Hi, |
2 |
|
3 |
On my new motherboard there is a on-board audio |
4 |
chip: Realtek ALC892 |
5 |
|
6 |
After a lot of searching and configuring it seems |
7 |
to work according to the log - but according to |
8 |
my ears it does not: There is no sound. |
9 |
|
10 |
Setup: Motherboard is a MSI Tomahawk Max and |
11 |
an Nvidia RTX 2060 SUPER (it has a HDMI audio device). |

According to that, soundcard 1 is what I want. |
43 |
I am using simple stereo speakers, which are connected to the rear I/O |
44 |
shield of my motherboard, which in turn has direct contact to the |
45 |
motherboard, so no possible faulty cables are involved. The speakers |
46 |
are ok since touching the contacts gives a buzzing 100Hz hum. |

It looks like the default sound card is sound card 1 indeed, which is |
115 |
the ALC892 |
116 |
|
117 |
But aplay -i gives: |
118 |
ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.2/work/alsa-lib-1.2.2/src/pcm/pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slave |
119 |
aplay: main:830: audio open error: No such file or directory |
120 |
[1] 18362 exit 1 aplay -i |
121 |
|
122 |
When trying to play an audio file with mpv gives a similiar error like |
123 |
that one aplay reports. |
124 |
|
125 |
Alsamixer has no problems: It let my choose between the two sound |
126 |
cards and when choosing sound card 1 (ALC892) I can manipulate |
127 |
the volumes of the different channels. |
128 |
No channel is muted. |
129 |
All channels have a reasonable volume setting. |
130 |
|
131 |
Where is this [CENSORDED] error/bug, which prevents audible sound |
132 |
output? |
133 |
|
134 |
Thanks for any helpful advice in advance! |
135 |
|
136 |
Cheers! |
