[Alsa-devel] Re: [Alsa-devel] lockup ice1712 cs8427
Lockup with cs8427 and Abit VP6 still remains with alsa0.9beta9; I made tries - keeping only audio device on - working on irq resources, but still no chance. I do have more informations though. Launching amixer contents on all the numIDs, I found that system locks up on the first one, that is 'IEC958 CS8427 Input Status'. I ask if there is a problem on snd_i2c_lock (btw is it possible a debug-patch on the function?), or on the address of CS8427 which is fixed. All the other contents return easily the values. Are there any little program which scans and probes CS8427 address?

Re: [Alsa-devel] EWS64XL: cs4232 alsa driver is no more workingwith Alsa 0.9.0beta12 and Sam9407 driver , Alsa0.5.x worked fine
Hello Ok, now i tried the CS4236 driver, but i get still the same errors. I think its a bug, something is really messed up. I also tried the old ALSA 0.5.x drivers again but i get the same errors now. It must have something to do with the upgrade from Kernel 2.4.9 to 2.4.18, because now, no version from ALSA works anymore, no ALSA 0.9.x and no ALSA 0.5.x As i said in the mail before ALSA 0.5.x worked with Kernel 2.4.9.

[Alsa-devel] capture with non-interleaved mode
Hi. I'm developping a signal processing program which needs to compute data from each channel of soundcards separately. After searches I found that I must open the soundcard with the SND_PCM_ACCESS_RW_NONINTERLEAVED flag but it doesn't works well : for each readn operation i get the -32 error code . Meanwhile, I tested capture in interleaved mode and it works well. I had to use hw:x,y for the interleaved capture and plughw:x,y for the non- interleaved capture, I don't know if non-interleaved capture works with hw:x,y. Any advice (or piece of source code) ?

I join the relevant parts of the source (without error handlers) :
#define BUF_SIZE 128
struct snd_card
{
snd_pcm_t *handle;
snd_pcm_hw_params_t *params;
short inputBuffer[BUF_SIZE*2];
void *buffer[2];
};
typedef struct snd_card snd_card_t;
int
main ()
{
char card_id[32];
int err;
itn card = 0;
snd_card_t *card1;
card1 = calloc(1,sizeof(snd_card_t));
card1->buffer[0] = card1->inputBuffer;
card1->buffer[1] = &card1->inputBuffer[BUF_SIZE];
snprintf (card_id, 32, "plughw:%d", card);
snd_pcm_open (&card1->handle, card_id, SND_PCM_STREAM_CAPTURE, 0);
snd_pcm_hw_params_malloc (&card1->params);
snd_pcm_hw_params_any (card1->handle, card1->params);
snd_pcm_hw_params_set_channels (card1->handle, card1->params, 2);
snd_pcm_hw_params_set_access (card1->handle, card1->params,
SND_PCM_ACCESS_RW_NONINTERLEAVED);
snd_pcm_hw_params_set_format (card1->handle, card1->params,
SND_PCM_FORMAT_S16_LE);
snd_pcm_hw_params_set_rate_near (card1->handle, card1->params, ECHANT, 0);
snd_pcm_hw_params (card1->handle, card1->params);
snd_pcm_hw_params_free (card1->params);
snd_pcm_prepare (card1->handle);
while (...)
{
err = snd_pcm_readn (card1->handle, card1->buffer, BUF_SIZE);
printf("err=%d, buff=%d\n", err, card1->buffer[0]);

I've not managed to fix this bug into my program... Do you see the error on my
code (bad soundcard initialization or other) or have you got another way to
propose me to capture the two channels of my soundcard separately ?

Re: [Alsa-devel] capture with non-interleaved mode
Hi !
I managed to capture sound but I have a problem due to the stereo. It is
impossible to capture data of channels separately.
I made a test for that : I have generated a sound with a square frequency of
2000 Hz in the left channel and a square frequency of 6000 Hz in the right
channel. And when I capture this sound I only have the sound of the right
channel : in the buffer I have the data of the right channel, but the data of
the left channel is replaced the right one.
I think that the stereo is taken only from the right channel (the signal is
exactly the same at the same time).
I join you the source of my program, if see the error...

sleep(1); // wait until the suspend flag is released
if (err < 0)
snd_pcm_prepare (card1->handle); // prepare again to read
}
}
snd_pcm_close (card1->handle);
return 0;
}
And here is a very small part of the text file obtained, we see the data of left
channel is always the same as the right (altough the frequencies of each channel
are differents).

[Alsa-devel] Emu10k1-sound corrupted
Hello to everyone. I'm using Mandrake 9.2 with Kernel 2.4.22 and the alsa 0.9.6drivers. The installation (compiled from source with gcc3.1.1-2) went fine but I could hear sound only from one channel. Raising all the volume controls up to the top, most of the times fixes the problem, but the sound is still no clean and sometimes goes back mute from one channel. Tried also the latest drivers and with a new kernel (2.6.1 with the alsa modules that come from it), but the problem's still there. Also, I noticed thata the sound is affected by the movements of the mouse (PS2). Can anyone help? Thank you for your support. mass --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

[Alsa-devel] emu10k1x patch
A few minor fixes to the emu10k1x driver. Also, it would be nice to update the soundcards page to list it as supported (mention that only PCM playback is currently supported). I will try to test a few more things before 1.0.5 gets final, I hope.
