alsa-project/alsa-ucm-conf pull request #601 was opened from strongtz: This is an upcoming SBC (single board computer) based on QCS6490. Full specs: - Headphone jack using WCD9380 codec - Onboard DisplayPort to HDMI bridge using Radxa RA620 - MI2S0 available via the 40-Pin GPIO header (unused by default) - AMICs using WCD9380 codec via a dedicated MIC header (unused by default) The kernel device tree part is not yet but going to be upstreamed soon.

[HDA][HP EliteDesk 800 G5][8086:a348] – HDMI audio missing after BIOS update
by Hermanns Cyrille 09 Aug '25

09 Aug '25

Hello ALSA team, On an HP EliteDesk 800 G5 Desktop Mini with BIOS R21 Ver. 02.22.00, audio controller Intel Cannon Lake PCH cAVS [8086:a348], HDMI audio outputs are no longer detected after this BIOS update. System: - Linux Mint 22.1 Cinnamon 6.4.8 - Kernel: 6.8.0-71-generic - Codecs: Conexant CX20632 (analog), Intel Kabylake HDMI (digital) Issue: After boot, HDMI outputs appear as “Not connected”. HDMI audio works only if I use hdajackretask (Intel Kabylake HDMI → Show unconnected pins → set to HDMI/DisplayPort) and select “Install boot override”. ALSA report: http://alsa-project.org/db/?f=a1ee220062b23ad5c13c6d38cde3f1d046ce6260 Request: Would it be possible to add a quirk for this model so HDMI pins are enabled automatically at boot? Thank you for your help.

Problems with "snd_pcm_hw_params_set_rate_near" and "snd_pcm_hw_params_set_period_size_near" in x86_64 assembly.

alsa-project/alsa-lib issue #471 was opened from sc1ntilla: ### **PREAMBLE:** I have never worked with any sound system before, so I'm almost sure that it's just me doing something wrong, but I can't see what, so I'm asking for help. I'm doing this project for fun, and to learn a lot of stuff, so feel free to give your opinions / advice if you want to. ### **WHAT HAPPENS:** When calling `snd_pcm_hw_params_set_rate_near` and `snd_pcm_hw_params_set_period_size_near` memory protection violation is issued. I find that strange, because `snd_pcm_hw_params_set_buffer_size_near` works perfectly fine, and it's similiar to these two. ### **WHAT I TRIED:** - Making sure that stack after call is on address divisible by 96 (by adding 8 to stack pointer), - Making sure that `*val` argument is on address divisible by 96, - Misaligning stack by 8, 16, 24 and 32 before calling these functions (by subtracting from stack pointer), - Providing 0 to `*val` argument, to rule out that writing to output crashes, - Providing valid output address to `*dir` argument to rule out that 0 is causing crashes, - Calling these functions in different order, - Trying to call `snd_pcm_set_params` instead, but it says _"Channels count (0) not available for PLAYBACK: Invalid argument"_ however, I'm sure that I provided a valid number (2). I even hardcoded it. But to no avail. Is it my misunderstanding of how alsa-lib works? Very likely. Is my assembly code faulty? Quite possible. I just can't see where the problem lies. If you see error somewhere, please let me know. ### **ADDITIONAL INFORMATION:** I have multiple audio outputs: monitors with built-in speakers, standalone speakers, and analog jack headphones. I hardcoded `hw:2,0` as device name to open. Sometimes it results in `snd_pcm_open` returning _"File descriptor in bad state"_. When I tried using `sysdefault` it often returns _"ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.14/work/alsa-lib-1.2.14/src/pcm/pcm_dmix.c:1000:(snd_pcm_dmix_open) unable to open slave"_ Below is .data section in which globals are stored, and source of function that will be used to play audio buffers. .data section: ``` .section .data .align 32 test2: .8byte 0 test: .8byte 0 SND_PCM_NONBLOCK: .8byte 0x1 SND_PCM_ASYNC: .8byte 0x2 SND_PCM_STREAM_PLAYBACK: .8byte 0 SND_PCM_FORMAT_U8: .8byte 1 SND_PCM_FORMAT_U16_LE: .8byte 4 SND_PCM_FORMAT_U24_LE: .8byte 8 SND_PCM_FORMAT_U32_LE: .8byte 12 SND_PCM_FORMAT_S8: .8byte 0 SND_PCM_FORMAT_S16_LE: .8byte 2 SND_PCM_FORMAT_S24_LE: .8byte 6 SND_PCM_FORMAT_S32_LE: .8byte 10 SND_PCM_ACCESS_MMAP_INTERLEAVED: .8byte 0 SND_PCM_STATE_PREPARED: .8byte 2 AUDIO_BUFFER_STATE_IDLE: .8byte 0 AUDIO_BUFFER_STATE_WRITING: .8byte 1 AUDIO_BUFFER_STATE_PLAYING: .8byte 2 t1: .8byte 0 t2: .8byte 0 alsa: alsa.pcm_handle: .8byte 0 alsa.hw_params: .8byte 0 alsa.last_error: .8byte 0 alsa.initialized: .8byte 0 alsa.device_name: .ascii "hw:2,0\0" audio_buffers.count_max: .8byte 16 amd64_audio_last_error: .8byte 0 ``` function: ``` amd64_audio_play: /* rdi: (input) address to audio data: * (+0/2) audio format (1: PCM, 2: IEEE754) * (+2/2) amount of channels * (+4/4) rate in hertz * (+8/4) bytes per sec (frequency * bytes per block) * (+12/2) bytes per block (number of channels * bits per sample / 8) * (+14/2) bits per sample * (+16/8) total size of samples data * (+24/8) address to samples data */ /* Align stack on 96byte boundary: */ push %r15 mov %rsp, %r15 and $-32, %rsp mov %rsp, %rax mov $96, %r14 xor %rdx, %rdx div %r14 sub %rdx, %rsp sub $96, %rsp mov %r15, (%rsp) /* Store registers: */ sub $192, %rsp call amd64_util_store_gpr_regs /* Create stack space: */ sub $192, %rsp mov %rdi, (%rsp) /* stack layout: * (+0/8) rdi (address to audio data) * (+8/8) buffer size (altered by *buffer_size_near) * (+16/8) period size (set when setting period size) * (+24/8) rate in hertz * (+32/8) temp */ xor %r15, %r15 mov 16(%rdi), %r15 mov %r15, 8(%rsp) xor %r15, %r15 mov 4(%rdi), %r15d mov %r15d, 24(%rsp) movq $0, 32(%rsp) /* Open pcm if needed: */ cmpq $0, (alsa.pcm_handle) jne .amd64_audio_play.pcm_is_open lea alsa.pcm_handle, %rdi mov %rdi, (%rdi) lea alsa.device_name, %rsi mov (SND_PCM_ACCESS_MMAP_INTERLEAVED), %rdx mov (SND_PCM_NONBLOCK), %r10 call snd_pcm_open cmp $0, %rax jne .amd64_audio_play.error.snd_pcm_open .amd64_audio_play.pcm_is_open: /* Allocate hw params: */ cmpq $0, (alsa.hw_params) jne .amd64_audio_play.hw_params_are_allocated lea alsa.hw_params, %rdi mov %rdi, (%rdi) call snd_pcm_hw_params_malloc cmp $0, %rax jne .amd64_audio_play.error.snd_pcm_hw_params_malloc .amd64_audio_play.hw_params_are_allocated: /* Get all possible combinations into hw params: */ mov (alsa.pcm_handle), %rdi mov (alsa.hw_params), %rsi call snd_pcm_hw_params_any cmp $0, %rax jne .amd64_audio_play.error.snd_pcm_hw_params_any /* Set access: */ mov (alsa.pcm_handle), %rdi mov (alsa.hw_params), %rsi mov (SND_PCM_ACCESS_MMAP_INTERLEAVED), %rdx call snd_pcm_hw_params_set_access cmp $0, %rax jne .amd64_audio_play.error.snd_pcm_hw_params_set_access /* Set format: */ xor %rdi, %rdi mov (%rsp), %rdi mov 14(%rdi), %r15w mov (%rdi), %r14w cmp $1, %r14w jne .amd64_audio_play.error.format_unsupported cmpw $32, %r15w je .amd64_audio_play.format32 cmpw $24, %r15w je .amd64_audio_play.format24 cmpw $16, %r15w je .amd64_audio_play.format16 cmpw $8, %r15w je .amd64_audio_play.format8 jmp .amd64_audio_play.error.format_unsupported .amd64_audio_play.format32: mov (SND_PCM_FORMAT_S32_LE), %rdx jmp .amd64_audio_play.format_end .amd64_audio_play.format24: mov (SND_PCM_FORMAT_S24_LE), %rdx jmp .amd64_audio_play.format_end .amd64_audio_play.format16: mov (SND_PCM_FORMAT_S16_LE), %rdx jmp .amd64_audio_play.format_end .amd64_audio_play.format8: mov (SND_PCM_FORMAT_S8), %rdx jmp .amd64_audio_play.format_end .amd64_audio_play.format_end: mov (alsa.pcm_handle), %rdi mov (alsa.hw_params), %rsi call snd_pcm_hw_params_set_format cmp $0, %rax jne .amd64_audio_play.error.snd_pcm_hw_params_set_format /* Set channels: */ xor %rdx, %rdx mov (%rsp), %r15 mov (alsa.pcm_handle), %rdi mov (alsa.hw_params), %rsi mov 2(%r15), %dx call snd_pcm_hw_params_set_channels cmp $0, %rax jne .amd64_audio_play.error.snd_pcm_hw_params_set_channels /* Set buffer size near: */ /* Returns 0, meaning it succeeded.
