[PATCH 01/10] ASoC: wm_adsp: Remove the wmfw_add_ctl helper function
by Charles Keepax 17 Nov '21

17 Nov '21

The helper function wmfw_add_ctl is only called from one place and that place is a function with only 2 lines of code. Merge the helper function into the work function to simplify the code.

Reference to the non-existing kconfig symbol SND_SOC_AC97_BUS_NEW
by Lukas Bulwahn 17 Nov '21

17 Nov '21

Dear Robert, In commit 1c8bc7b3de5e ("ASoC: pxa: switch to new ac97 bus support"), you changed the select in config SND_PXA2XX_SOC_AC97 from SND_SOC_AC97_BUS to the non-existing symbol SND_SOC_AC97_BUS_NEW. Hence, since then, ./scripts/checkkconfigsymbols.py is reporting this invalid reference: SND_SOC_AC97_BUS_NEW Referencing files: sound/soc/pxa/Kconfig Robert, it seems that you were already informed in the past and already acknowledged that some work is required to fix this in this email response: https://lore.kernel.org/all/878skf1zmp.fsf@belgarion.home/ As of next-20211117, this issue is still unaddressed, though. Are you going to address this issue? Is this patch just pending somewhere? Best regards, Lukas

how to get the log file of aplay
by GitHub issues - opened 17 Nov '21

17 Nov '21

alsa-project/alsa-utils issue #119 was opened from MT-LeiZhao: Hi guys, I'm a new guy for audio driver. I have added logs in my ko which have the pcm function. I can see the normal call stack log using pulseaudio. But I can't see any log about my driver through aplay. I guess there was something wrong in aplay. Can anyone tell me how to get the detail log for aplay? Thank you very much~~~ Issue URL : https://github.com/alsa-project/alsa-utils/issues/119 Repository URL: https://github.com/alsa-project/alsa-utils

HDMI driver format channel mismatch bug
by sujith kumar reddy 17 Nov '21

17 Nov '21

Hi Alsa Team, Sound is not coming in sony tv . which has below supported formats and channels. please find the attached edid information and hw_params dump. with intel platform, same monitor populating 2 channels as max in hw_params in dump. but with AMD card, its populating as 6 channels. When we digged the code, we found that snd_hdmi_eld_update_pcm_info API setting hinfo->channel_max as 8 and as channels max retrieved from sad info as 6. for LPCM , why the channel max assignment logic is not safeguared with audio format check as LPCM ? snippet code: /* update PCM info based on ELD */void snd_hdmi_eld_update_pcm_info(struct parsed_hdmi_eld *e, struct hda_pcm_stream *hinfo){ u32 rates; u64 formats; unsigned int maxbps; unsigned int channels_max; int i; /* assume basic audio support (the basic audio flag is not in ELD; * however, all audio capable sinks are required to support basic * audio) */ rates = SNDRV_PCM_RATE_32000 | SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000; formats = SNDRV_PCM_FMTBIT_S16_LE; maxbps = 16; channels_max = 2; for (i = 0; i < e->sad_count; i++) { struct cea_sad *a = &e->sad[i]; rates |= a->rates; if (a->channels > channels_max) channels_max = a->channels; if (a->format == AUDIO_CODING_TYPE_LPCM) { if (a->sample_bits & AC_SUPPCM_BITS_20) { formats |= SNDRV_PCM_FMTBIT_S32_LE; if (maxbps < 20) maxbps = 20; } if (a->sample_bits & AC_SUPPCM_BITS_24) { formats |= SNDRV_PCM_FMTBIT_S32_LE; if (maxbps < 24) maxbps = 24; } } } /* restrict the parameters by the values the codec provides */ hinfo->rates &= rates; hinfo->formats &= formats; hinfo->maxbps = min(hinfo->maxbps, maxbps); hinfo->channels_max = min(hinfo->channels_max, channels_max); >>>>>>>>>>the above statement channels_max is the maximum of channels supported of different formats. For example: the below attached edid is of sony tv. which supports two formats(LPCM and AC3) LPCM --->supports 2 channels AC3 ----->Supports 6 channels you can see in the attached edid info. As AMD supports LPCM ...>when we keep logs here we got channels_max =6 .in which sound is not observed on tv .when we hardcode to 2 channels the sound is heard from monitor. As you see the above code ..for loop is not distinguishing channels_max for different formats. } Thanks in Advance https://pastebin.com/t41DqErH ------edid information https://pastebin.com/4m56h10R -----dump hw-params Thanks Sujith

Currently same slim channel map setup for every dai link, which is redundant. Fix this by adding a flag and conditionally setting these channel maps.
