[PATCH 0/2] ARM/sound: fix audio on kirkwood-openrd-client

[Aaro Koskinen]

Hi,

Audio playback has been broken some time on OpenRD client. With the
following patches I got the audio file playback working with mplayer.

Aaro Koskinen (2):
  ARM: DTS: kirkwood-openrd-client: fix audio
  ASoC: simple-card: don't fail if sysclk setting is not supported

[PATCH 1/2] ARM: DTS: kirkwood-openrd-client: fix audio

[Aaro Koskinen]

Fix audio on kirkwood-openrd-client:

1) The audio-controller was left disabled.

2) The probe fails because cs42l51 is missing #sound-dai-cells.

	/sound/simple-audio-card,codec: could not get #sound-dai-cells for /ocp@f1000000/i2c@11000/cs42l51@4a
	asoc-simple-card sound: parse error -22
	asoc-simple-card: probe of sound failed with error -22

3) The mapping is incorrect:

	asoc-simple-card sound: cs42l51-hifi <-> spdif mapping ok

   should be:

	asoc-simple-card sound: cs42l51-hifi <-> i2s mapping ok

If someone will make a .deb I can download, I'll be happy to install it and test it.  Please be explicit in describing what and how you want tested.

Got it.

Looks like mmc works with that kernel.  I was able to mount /dev/mmcblk0p1 and read files from it.

Sound we have some progress:

Full of hope, I did "aptitude install mp321" which went without any visible problems.

Then hooked up a pair of earphones to the "speaker" plug on the Client and ran

So it seemed to be running OK...  But there was no sound in the earphones.  I also tried adding option "-g 50" to set the gain explicitly.  Still no sound.

Is there a hardware jumper I need to set to activate sound on the OpenRD Client board?

Do I need to install another package? For example, "aptitude search '~i alsa'" gives no output, indicating, I believe, that there are no installed packages with "alsa" in their name.

The message:
> ALSA lib pcm.c:2267:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.front
seems suspicious.

Any thoughts?
Rick

On my board I need to say "amixer set PCM on". Can you post the full
output from "amixer" without any parameters?

Also check if you have this line in dmesg:

	asoc-simple-card sound: cs42l51-hifi <-> i2s mapping ok

If it says "spdif" the player runs but is silent.

Martin suggested that I install alsa-utils and run alsamixer in order to remove any extraneous "mute" setting.  I did that (I didn't realize alsamixer was runnable from the command line -- good to know!)

I did that and it worked!  "The Jersey Bounce" never sounded so good!

I'll do the tests that Aaro suggest, just for completeness, but it will have to wait til later tonight.

So we can add --

[PATCH 2/2] ASoC: simple-card: don't fail if sysclk setting is not supported

[Aaro Koskinen]

Commit e22579713ae1 ("ASoC: simple card: set cpu-dai sysclk
with mclk-fs") added sysclk / SND_SOC_CLOCK_OUT setting, that makes
asoc_simple_card_hw_params fail if the operation is not supported,
although the intention clearly was to ignore ENOTSUPP. Fix it.

The patch fixes audio playback on Kirkwood / OpenRD client,
where the following errors are seen:

	asoc-simple-card sound: ASoC: machine hw_params failed: -524
	alsa-lib: /alsa-lib-1.0.28/src/pcm/pcm_hw.c:327:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS failed (-524): Unknown error 524

Fixes: e22579713ae1 ("ASoC: simple card: set cpu-dai sysclk with mclk-fs")
