Getting Alsa / sound working

<< < (2/3) > >>

Jason W:
Try using no spaces after the comma in between the entries in your "blacklist=" bootcode and see if that helps.

Jason W:
Also, post your resulting /etc/modprobe.d/blacklist.conf file after booting.   Thanks. 

EDIT:  I tested with a "blacklist=snd_mixer_oss, snd_seq_oss, snd_pcm_oss" entry and saw the same error message of:  modprobe: bad line 2: 1 tokens found, 2 needed.  I changed it to "blacklist=snd_mixer_oss,snd_seq_oss,snd_pcm_oss" and no error, so that explains at least that error message.

Thanks, that has resolved that error (I tried blacklisting the OSS modules after reading something about this in the wiki in relation to intel hda soundcards). My issue is really that I'm not sure which troubleshooting steps to go through, and whether I should only be using modprobe in the command line or editing a conf file. I've been reading up quite a lot on Alsa and the errors I've encountered but as a newb I struggle to understand it or the examples are for different soundcards and I don't know how to adapt (e..g there is kots of good info on https://alsa.opensrc.org/Sound_cards and associated pages but I've been unable to use it effectively so far).

Reloading Alsa now gives:


--- Code: ---sudo alsa reload

amixer stille gives:


--- Code: ---amixer: Mixer attach default error: No such file or directory

--- End code ---

blacklist.conf:

--- Code: ---blacklist snd_mixer_oss
blacklist snd_seq_oss
blacklist snd_pcm_oss

--- End code ---

I also read about editing the index numbers in the conf file but am unsure if this applies to my issue.

Thanks very much for the help, much appreciated.

liam391:
Tinycore wiki gives the following advice - this is not available as an sce in dCore I believe but should I take this from Tinycore repos to perform the below?


--- Code: ---alsaconf when the aplay list is empty

If you downloaded alsa and its in your onboot list and you rebooted, you should have sound devices configured. You may need to adjust the mixers to hear sound. However, if

aplay -l
does not show any devices, then download alsaconf so its also an “onboot” tcz and reboot to retest your sound. If on reboot, no sound devices are detected, then run

sudo alsaconf
and follow the prompts to search and configure your sound device.


--- End code ---

Jason W:
You can try the alsaconf script, I will review it and see if it would work with dCore and make adjustments if needed and upload it to the prebuilt section.
