Hi Mark
I noticed if we have...
1) Sound Card used DPCM
2) It exchanges rate to 48kHz by using .be_hw_params_fixup()
3) Codec had symmetric_rate = 1
We will get below error.
I didn't confirm, but maybe same things happen
if it exchanged channels/sample_bits.

__soc_pcm_params_symmetry() macro is using "name" as parameter
which will be exchanged to rate/channles/sample_bit, like below
dai->name => dai->rate
dai->name => dai->channels
dai->name => dai->sample_bit
But, dai itself has "name". This means
1) It is very confusable naming
2) It can't use dai->name
This patch use "xxx" instead of "name"

It indicates unmatched symmetry value, but not indicates on which DAI.

There is snd_soc_dai_is_dummy(), but not for component.
This patch adds it.

soc_pcm_params_symmetry() checks CPU / Codec symmetry.
Unfortunately there was bug on it (= A) which didn't check Codec.
But is back by (B).
A: v5.7: commit c840f7698d26 ("ASoC: soc-pcm: Merge for_each_rtd_cpu/codec_dais()")
B: v5.12: commit 3a9067211122 ("ASoC: soc-pcm: cleanup soc_pcm_params_symmetry()")
In total,
old - v5.6 (= Generation-1):
symmetric_rate : DAI_Link / CPU / Codec
symmetric_channels : DAI_Link / CPU / Codec
symmetric_sample_bits : DAI_Link / CPU / Codec
v5.7 - v5.11 (= Generation-2): (= because of bug by (A))
symmetric_rate : DAI_Link / CPU
symmetric_channels : DAI_Link / CPU / Codec
symmetric_sample_bits : DAI_Link / CPU / Codec
v5.12 - (= Generation-3): (= back by (B))
symmetric_rate : DAI_Link / CPU / Codec
symmetric_channels : DAI_Link / CPU / Codec
symmetric_sample_bits : DAI_Link / CPU / Codec
OTOH, we can use DPCM which is configured by FE / BE.
Both FE / BE uses dummy-DAI.
FE: CPU <-> dummy-DAI
BE: dummy-DAI <-> Codec
One note is that we can use .be_hw_params_fixup in DPCM case.
This means BE settings might be fixuped/updated by FE.
This feature is used for example on MIXer case.
It can be happen not only for rate, but for channels/sample_bits too.
Because of these reasons, below issue happen on
Generation-1 / Generation-3, if...
1) Sound Card used DPCM
2) It exchanges rate to 48kHz by using .be_hw_params_fixup()
3) Codec had symmetric_rate = 1
I didn't confirm, but maybe same things happen
if it exchanged channels/sample_bits at Generation-1/2/3 too.

soc_pcm_params_symmetry() checks by below
if (symmetry)
for_each_rtd_cpu_dais(rtd, i, cpu_dai)
if (cpu_dai->xxx && cpu_dai->xxx != d.xxx) {
dev_err(rtd->dev, "...");
return -EINVAL;
}
Because of above reason 3) (= Codec had symmetric_rate = 1)
BE can't ignore "if (symmetric)".
At 1st aplay, soc_pcm_params_symmetry() ignores it,
because dummy-DAI->rate is 0.
After this check, each DAI sets/keep settings.
In above sample case, BE gets 48000 and FE gets 44100,
and it happen BE -> FE order.
Because DPCM is sharing *same* dummy-DAI,
dummy-DAI sets as 48000 by BE, and is overwrote by 44100 by FE.
This settings never be cleaned (= a) after 1st aplay,
because dummy-DAI is used from FE/BE, never be last user (b).
static int soc_pcm_hw_clean(...)
{
...
for_each_rtd_dais(rtd, i, dai) {
...
(b) if (snd_soc_dai_active(dai) == 1)
(a) soc_pcm_set_dai_params(dai, NULL);
...
}
...
}
At 2nd aplay, BE gets 48000 but dummy-DAI is keeping 44100,
soc_pcm_params_symmetry() checks will fail.
To solve this issue, this patch ignores dummy-DAI
at soc_pcm_params_symmetry()

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
