s3c2443-uda134x sound driver problem

Oleg — 2013-05-01T13:14:32

Hello

I need to write a driver for codec uda134 installed on plat with processor s3c2443. I use driver for uda134 that is already in the kernel 3.6 (s3c24xx-uda134x) and IIS driver (s3c24xx-i2s). IIS driver is not compatible with processor s3c2443, and I changed in that iis registers and a few functions (attching patch). I have a problem with sound output. When audio file is playing sound interrupts (using alsa 1.0.26). Here is a part of debug output (output1.txt). Time between end of enqueue and start of the next buffdone is about 0.5 second, but expected is about 0.1 second. It seems that problem is size of dma buffer. I tried to forcibly change size of buffer
in kernel/linux/sound/soc/samsung/dma.c, line 212

prtd->dma_end = prtd->dma_end - (prtd->dma_end - prtd->dma_start)/2;    

and interrupt disappeared, but sound distorted. Here is a part of debug output is such conditions (output2.txt). Here time bitween end of enqueue and start of the next buffdone satisfactory

Trying to get surround sound working on my Dell L702x Laptop

Kronos — 2013-04-27T18:32:16

I have a Dell L702x Laptop with an Intel Cougar Point HD Audio 
soundcard. In windows you are able to put it in analog surround sound 
mode - that is you have 3 3.5mm jacks running as output with 2 channels 
each. I am trying to replicate this behaviour so I can use the card as a 
6 channel output device with jack audio and ardour


(my setup works in stereo mode - now if i could just get the card to 
show 6 channels instead of just 2 - heck even 4 channels would be an 
improvement)
What do I need to do to make this work?

relevant sound routing:
soundcard > alsa > jack > aurdour  < pulse

  (I basically route all my sound through aurdor for effects processing 
- then out to the soundcard)



I'm running on Fedora 18

[RFC] Sound/HID: wiimote: add speaker support

David Herrmann — 2013-04-20T18:07:53

Classic Wii Remotes provide a speaker on the device. We can stream PCM
data, mute and change volume via special protocol requests and remote
audio registers.

The device supports several different formats, but fully understood are
only signed 8-bit PCM and something that looks like 4-bit Yamaha ADPCM.
Theoretically, we can set data-rates from 183Hz up to 12MHz, but a
realistic range for Bluetooth l2cap is 1500-4000 Hz.

Data is streamed as 20bytes blocks and must be sent in a constant rate.
There is no way to read the current position. It would be way too slow,
anyway.

Hi

I'm reworking large parts of the HID Nintendo Wii Remote driver and wanted to
add speaker support. I have never worked with the sound subsystem until now
and need some help.

The Wii Remote is a Bluetooth gamepad that features a small speaker on the
remote. All information was gathered via reverse-engineering so I cannot tell
you any specifics about the hardware, sorry. What I figu

Re: Sound/ARM/i.MX/SSI: fix SDMA starvation

Thanks for the fix, Juergen.

The patch subject could be written in a better form with a proper
prefix added.  "git log sound/soc/fsl/fsl_ssi.c" should give example.
To have the patch get in sooner, you should copy Mark Brown on it.

Also MAINTAINERS file gives the following, so you still do not have
the right list copied.

Sound/ARM/i.MX/SSI: fix SDMA starvation

Juergen Beisert — 2013-01-24T08:56:30

In cases when capturing is already running and someone enables also
playback, the SDMA unit of the i.MX SoC does not see an edge on its TX DMA
request line. This is due to the TX FIFOs are empty, and this request line is
active all the time, when the CCSR_SSI_SIER_TDMAE bit is set.
In this case also the TX FIFO underrun interrupt will flood the system forever.

To ensure the first edge happens after enabling the TX side of the SSI unit and
to trigger the SDMA unit successfully enable the CCSR_SSI_SIER_TDMAE on
demand only. To be sure, this patch does the same for the CCSR_SSI_SIER_RDMAE
(RX side) bit.

Olof Johansson — 2013-01-11T19:53:31

That's a noble goal but enforcing it early gives everyone a lot of pain, and
quite honestly doesn't make sense. During transition it's better to be lenient
and allow both old and new methods (without breakage), unless it causes
significant extra churn.


The problem is that at91 tries to do too much in a single release, and then do
nothing in several releases after. If there was a steadier trickle of code
coming in, then these kind of complex dependencies wouldn't show up all at
once, and could be handled with much less overhead for everyone else involved.
:(


To be honest, if Atmel can't figure out how to merge a complete feature
without causing intentional regressions during the merge window, and plan
on brokenness to be fixed as late as in -rc4, then they deserve to have
a broken platform. Unfortunately the victim of that is end users, and we
don't want to leave them hanging. This really can't become a trend though.

Sigh. Feel free to add:
