[Kernel-packages] [Bug 1851518] Re: [950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on internal speakers, very very quiet on headphones
@John Hoff > Namely, I followed the same procedure as before with the headphone patch, but right before I made the new custom kernel I just added the new candidate CORB values to the new patch_realtek.c file in my new custom header... so basically just modified the samsung headphone very quiet fixup (partial sample below). Looks good to me. > I guess I can try again with the full halt and restart process as listed in the openbsd article... Good idea. No one promised us that this would work. However, we gave it a try, which is what Jaroslav asked us to do way back in May (see bugzilla comment 14 [1]).

@John Hoff > Mike, depending on your answers to my many questions from today, if the only way we know to proceed is to build and test a patch, could you help with building the patch (or at least the basic framework of the patch so I can just plug in the CORB values)? Absolutely. I'll write a patch and test it on my machine, after which I'll share it with you. In the mean time you could try Early Patching. Your Early Patching file will have an enormous [verb] section which will look like this [verb] 0x1a 0x707 0xc5 . . . Each line contains three space-separated hex values: Node ID, Verb ID, and Payload. You will have one line for each verb in the CORB dump, so that could be 1000s of lines. I think hda-verb < Early Patching < kernel patch, in the sense that a kernel patch has the highest-probability of success, hda-verb has the lowest, and Early Patching is somewhere in between. This is because I think that some codec values are read-write at initialization time but then become read-only at runtime (only Realtek, the ALC298 manufacturer, knows for sure*). A kernel patch allows us to write values at codec initialization time, whereas hda-verb is at runtime, and Early Patching is somewhere in between. *Perhaps we can know: I found a datasheet for the ALC269 [1]. I think the ALC269 is very similar to the ALC298 codec in our laptops. Among other things, the datasheet describes verb semantics. It's a nice supplement to the Intel HDA spec. I don't recall seeing anything about initialization-time vs runtime, but perhaps I have not read it closely enough - the datasheet is only somewhat less dense and technical than the Intel HDA spec so it's not an easy read! :) [1] https://www.hardwaresecrets.com/datasheets/alc269.pdf -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1851518 Title: [950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on internal speakers, very very quiet on headphones Status in linux package in Ubuntu: Confirmed Bug description: I've been googling this issue for 10's of hours and tried many things.

Can you re-attach? I don't see it.
> Anyway, thoughts? Do you have any more clarity on how to replay the
CORB commands?
Take a look at this patch [1]. Use the CORB command recording to write a
similar patch. It will contain a 2034-entry long array of hda_verb
structs [2]. Each hda_verb contains
{Node ID, Verb ID, Payload}
Apply your patch, compile, and run.

[Kernel-packages] [Bug 1851518] Re: [950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on internal speakers, very very quiet on headphones
@John Hoff John, great work! > Now what? I am not sure what to do with any of this data Now the hard part. Here's what I think is going on: The windows driver running in the VM controls the audio codec. How? According to section 4.4 of the Intel HDA Spec [1], the driver writes to a circular buffer known as the Command Output Ring Buffer (CORB). The HDA controller, which is implemented by the hardware manufacturer and shipped as firmware in the chipset, takes commands from the CORB and sends them to the codec. Qemu provides the memory for the VM. That means qemu can see every time the VM writes to memory. That's a lot of writes! We only care about the subset of writes to the memory region allocated for the HDA controller, which is what we get when we specify "vfio_region_write" event tracing. My laptop has this HDA controller 00:1f.3 Multimedia audio controller [0401]: Intel Corporation Cannon Point-LP High Definition Audio Controller [8086:9dc8] (rev 11) so when I see qemu output a trace line that looks like 3064@1591386653.159507:vfio_region_write (:00:1f.3:region0+0xe, 0x7fff, 2) I know that the driver wrote to the HDA controller memory because the pci device id "1f.3" matches the HDA controller. We can decode the rest of the line by looking at the qemu source code [2]. 0xe is the memory offset at which the driver wrote, 0x7fff is the data, and 2 is the size of the data in bytes. Which vfio_region_write events are CORB writes? The answer requires an understanding of the CORB protocol. The CORB has a fixed size which may be up to 256 entries. That means that all CORB writes are made to memory within a CORBSIZE range of addresses. After the driver writes an HDA verb to the CORB, the driver writes a value from 0x0 to 0xff to the CORB Write Pointer (CORBWP) register which tells the HDA controller the last valid CORB entry offset so the HDA controller knows how far to read before stopping and waiting for more data. Enter QemuHDADump (QHDAD). QHDAD is a program that someone wrote and published on github which attempts to parse vfio_region_write lines from qemu to determine the CORB address and record all HDA verbs written to the CORB. The author of QHDAD has his/her own hardware and did not test it on my laptop or your laptop so it is likely buggy and therefore may not produce a good recording of verbs. We don't have to use QHDAD; we just need some way to parse CORB writes from vfio_region_write events. Because the speaker sound works on Windows that means that if we send the verbs in the recording to the HDA controller using snd_hda_intel we may be able to get the speakers work on Linux. Once we demonstrate that the speakers function after passing all the verbs in the recording we need to minimize the verbs if we want any hope of our patch being included in the kernel. Many of the verbs will be "getters" instead of "setters" which we can delete. After that it may be a tedious trial-and- error process to see which of the remaining verbs we can delete. The verb encodings are specified in the Intel HDA Spec which can help us guess what can be deleted. The end goal is a patch which looks like this one [3].

@John Hoff @PowerKiKi Is "Samsung Galaxy Book Ion (NT950XCJ-X716A)" not a correct description of John's laptop? If not, it doesn't matter to snd_hda_intel which only looks at the subsystem id (0x144dc18a), but it's worth changing it for the benefit of any humans who read the kernel code. I use the output from alsa_info.sh and dmidecode to determine the subsystem id and what to put for the string description, but I don't have your hardware so I can't check the output for you, which is how I (possibly) made a mistake in writing the description string. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1851518 Title: [950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on internal speakers, very very quiet on headphones Status in linux package in Ubuntu: Confirmed Bug description: I've been googling this issue for 10's of hours and tried many things.

[Kernel-packages] [Bug 1851518] Re: [950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on internal speakers, very very quiet on headphones
@John Hoff The windows VM is the key. It's the top layer of the 3-layer cake. The middle layer is linux and the bottom layer is the hardware. In linux we record the windows driver communicating with the audio codec in the hardware's firmware with the hope that we can play back the recording in the linux driver. Comment 19 [1] shows my excitement when I got the VM working. Specifically, I had a windows VM in which I could play audio and hear it in the speakers. I could see the windows driver communication with the audio codec in the VM's IOMMU. I can help you get to this point, which is where I'm stuck.

@John Hoff Woohoo!!! Way to go John! That's great news. I submitted a patch to LKML (see attached). The content is the same as the patch that worked for you; all I did was change the commit message. Hopefully it lands in your favorite kernel distribution soon. :) > Is there anything I can do to help with the speaker investigation? Yes, come over to the kernel bugzilla and read what I've written [1]. Comment 28 lists a 2-step process - get a good trace then minimize the verbs - which has proven to be a significant technical challenge. Comment 24 describes where I left off in my quest for a trace.

@John Hoff > I notice in your comment you did a checkout of v5.8... does that make a difference? The fact that you were able to apply the patch and compile makes me think that a checkout of v5.8 would not make a difference. Can you try this patch instead? (See attached) Delete /etc/modprobe.d/alsa-base.conf because you don't need it anymore. This new patch instructs the driver, snd_hda_intel, to apply the quirk when it sees your machine, which it identifies by observing your subsystem id (0x144dc18a). I did *not* submit this new patch for inclusion in the kernel. I made it just for you to try.

Relase of Ubuntu: 19.10 Expected outcome: Music plays on the internal speakers and headphones. Actual outcome: I can barely hear audio using headphones with volume turned up to 150%. Absolutely nothing comes out of the speakers. (The speakers sound great under Windows 10.)
