[?]Are Realtek Audio Drivers for Linux available for use

#1 Post by bkpsusmitaa » 2021-03-12 08:29

The details of the Lenovo laptop, earlier with my daughter who used it with Doze OS, is now used by me, obtained from Hardinfo scan is here: Notes on some issues with lenovo laptop network set up .
The audio device can’t record audio while playing, i.e., in duplex mode. Pulse audio Volume Control or System tray can’t be used.
Using the Hardinfo data, the internet was searched for the said laptop, reaching the Lenovo site. The Motherboard audio appears to be from Realtek.
Lenovo doesn’t appear to have Linux drivers hosted for their laptops.
The Lenovo site says that the audio driver is Realtek audio drivers «Lenovo ideapad 320-15ISK» LNVNB161216 with the following details:
Realtek Audio_6.0.1.8652.A
Again checked the internet with the string:

Unable to find any Linux drivers for Realtek audio hardware device.
I am afraid that without Realtek drivers the audio hardware won’t work in Duplex mode with PulseAudio Volume Control or Pulse Audio System Tray packages.
Any help in this regard please?

The drivers are probably already included in the kernel (unless the hardware is too new for buster’s two year old kernel). Use ‘lspci -k’ to check if they’re loaded for the device. You probably just need the non-free firmware.

Thank you, «Head_on_a_Stick», for replying to my post. I am feeling horrible for the absence of duplex operations.

Please feel free to advise in further details please.

You don’t by any chance have a program called Timidity installed do you? The reason I ask is that it seems to block sound with this card for a lot of people.

Thank you for this suggesting a change of tack.
«No» in Debian stretch 9.11.0 and «Yes» in Knoppix 8.6.1. In the either of the two, pulseaudio doesn’t work. While in Debian it operates but doesn’t record in duplex, in Knoppix the pulseaudio Volume Control can’t establish connection to PulseAudio.
Have uninstalled Timidity in Knoppix. But no change in the end result.
I have also uninstalled the two packages appearing to be connected with timidity: libsdl2-mixer-2.0-0, ver 2.0.4+dfsg1-1libsdl-mixer1.2 and libsdl2-mixer-2.0-0, ver 1.2.12-15,
Thank you once again. Please keep at it. We all together shall ultimately achieve a breakthrough in this.

These two commands should tell you if there are any errors reported for the sound card either while the computer is booting up or running. Please post the output. I’m no expert, but I came across the commands while looking into a sound issue of my own. They may help you.

journalctl -k | grep -Ei "snd|sound|audio|multi"

The difference is immediately apparent in ordering of the lines. If you and i aren’t able to discern, there must be excellent systems admins who must be browsing these forums.
Would they address our issue? That’s the imperative question.

This is Debian Vs Knoppix, right? One seems to have recognised the Codec chip as ALC3227, the other is using a generic driver. Do you have firmware-linux-nonfree installed as Head_on_a_Stick suggested?

This Soundcard/chip/codec/driver whatever does seem to be vulnerable to being jammed up by sound apps like Timidity. Try

If anything apart from Pulse/Alsa are using sound, it could be a problem.

lspci -knn | grep -iA2 audio

There seem to be a lot of issues with this card producing less sound in Linux than Windows because it has two outputs and Linux uses the wrong one by default. This might help. Possibly. Maybe.

Of course ideally the person helping there could comment as he seems to know what he’s talking about. Maybe he’ll drop by.

You could try this too (it possibly does the same thing, so one or the other.
