Hi, I want to try the forward/rewind APIs supported by the ALSA library. Can someone point to an ALSA application which exercises these APIs? Best Regards, Anuj Aggarwal

[alsa-devel] hda_intel: SPDIF not detected on Asus P7P55D PRO
by Robert Hancock 06 Oct '09

06 Oct '09

I just set up a new system running an Asus P7P55D PRO motherboard. It looks like this uses the VIA VT1828S codec. The analog output seems to work but the SPDIF output isn't recognized. Originally tried 2.6.30.5, but Linus' current git doesn't seem any different. The device only gets detected as HDA Generic, which, from my reading of the code, ignores SPDIF outputs. I tried hacking patch_via.c to add the codec ID to match existing types like VT1708S and VT1702, each of those got the SPDIF output to show up, but no output showed up on the receiver, and also the analog output then stopped being recognized (looks like some node IDs don't match). Is there some extra support that needs to be added for this codec, or anything else I can try to get this working? The SPDIF does work in Windows 7 with just the standard Microsoft HDA driver.. aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic] Subdevices: 1/1 Subdevice #0: subdevice #0 The codec data seems to have references to the SPDIF output, but no device is actually getting created.

[alsa-devel] [PATCH] sound: Don't assume i2c device probing always succeeds
by Jean Delvare 05 Oct '09

05 Oct '09

If i2c device probing fails, then there is no driver to dereference after calling i2c_new_device(). Stop assuming that probing will always succeed, to avoid NULL pointer dereferences. We have an easier access to the driver anyway.

No, still there is a clear shshshshshsh sound in the background. Please check the attachment for a short arecord -f cd without me speaking on the mic and still you can hear this noise very clear.

[alsa-devel] [PATCH] Don't check if period size is equal to buffer size
by Lubomir Rintel 02 Oct '09

02 Oct '09

At least some drivers seem to allow a single period and those which don't would correct us anyway. Moreover, Pulseaudio with tsched sets this frequently. --- aplay/aplay.c | 5 ----- 1 files changed, 0 insertions(+), 5 deletions(-) diff --git a/aplay/aplay.c b/aplay/aplay.c index c7c82a1..4fa36cb 100644 --- a/aplay/aplay.c +++ b/aplay/aplay.c @@ -1044,11 +1044,6 @@ static void set_params(void) } snd_pcm_hw_params_get_period_size(params, &chunk_size, 0); snd_pcm_hw_params_get_buffer_size(params, &buffer_size); - if (chunk_size == buffer_size) { - error(_("Can't use period equal to buffer size (%lu == %lu)"), - chunk_size, buffer_size); - exit(EXIT_FAILURE); - } snd_pcm_sw_params_current(handle, swparams); if (avail_min < 0) n = chunk_size; -- 1.6.2.5

[alsa-devel] Patches for alsactl init db
by Dan Chen 02 Oct '09

02 Oct '09

Hi, Attached are two patches against alsa-utils.git HEAD that create an intel8x0 init db file for ICH4. This is necessary from bug reports in Debian and Ubuntu that state that External Amplifier must be muted to have audible (analog) playback by default on the Sony VAIO VGN-T350P. Thanks, Dan

[alsa-devel] [PATCH 0/1] ASoC: debugfs support improvement
by Peter Ujfalusi 01 Oct '09

01 Oct '09

Hello, I have noticed that the support for multiple cards/codecs via the debugfs is kind of broken. The second codec, which tries to create the debugfs files would emit the following messages: ASoC: Failed to create codec register debugfs file Failed to create pop time debugfs file ... The following patch fixes this by adding a directory per codec to host the files. The additional directory is named as codec->name, so it is easier to find the correct codec we are looking for. --- Peter Ujfalusi (1): ASoC: add support for multiple cards/codecs in debugfs include/sound/soc.h | 1 + sound/soc/soc-core.c | 21 ++++++++++++++------- 2 files changed, 15 insertions(+), 7 deletions(-)
