[SOLVED] ALSA: Playback open error: -2,No such file or directory

EscapedNull · 2014-09-05 23:41:35

I'm setting up a fresh Arch installation on a new system, and I'm stuck at ALSA. The hardware seems to be detected just fine, kernel modules are in place, and cards are available in alsamixer. The problem is that I have not heard any sound through all the testing I've done so far, and furthermore speaker-test outputs an error on some commands.

That's the gist of it, anyway. I can provide more information as needed. Assistance is much appreciated!

Disclaimer:
I usually put more time into solving problems on my own before posting on the forum, but I'd like to have this fixed as quickly as possible as audio is rather important. With that having been said, I haven't read the ALSA documentation, nor the alsa-utils manuals. I don't really understand the difference between a "card" and a "device" and a "mixer" and a "PCM", so feel free to give me the RTFM.

Edit: solved.

Well, I have no idea what I just did or why, but it worked! I'll dig into the details when I have some free time. Thanks!

You are welcome. Additional explanation has been added at the referenced post, read the whole thread or search for my other posts, then it should be clear. For the record, this is the correct solution:

$ cat /etc/modprobe.d/50-alsa.conf
options snd-hda-intel index=1,0

Edit: And remember to mark the thread as solved.

HI, another newbie here with the exact same problem, except for the fix didn't work for me.

$ cat /etc/modprobe.d/50-alsa.conf
options snd-hda-intel index=1,0

The variable is set just like in emeres's solution, but there was no change the output of speaker-test.

$ speaker-test -D default -c 2

speaker-test 1.0.28

Playback devices is default
Stream parameters are 4800Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmis_open) unable to open slave
Playback open error: -2, No such file or directory

Does anyone have any other information relating to how to fix this, am I just an idiot?

@chickengod37 Please start a new thread describing your issue in detail also give output of

cat /proc/asound/cards
