[alsa-devel] SALSA library and recording
by Manisha Sankpal 16 Apr '09

16 Apr '09

Hi All, I am using salsa library to capture the data from the sound card. The requirement is that the recording should be done from line-in port of the sound card. The selection of "Line-in" port should be done programatically. With ALSA library, I am able to select the line-in by calling snd_mixer_selem_set_capture_switch_all() function. However, this function is returning an error when SALSA library is used. Is there any other function/way to select the line-in mixer element in the SALSA API? The help would be appreciated. Thanks & regards, manisha

[alsa-devel] [PATCH] Intel8x0: Remove conflicting quirk for SSID 0x103c0934
by Daniel T Chen 16 Apr '09

16 Apr '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 While cleaning up quirks, I noticed that there is a duplicated quirk for the SSID 0x103c0934. Looking back through the bug reports, I've concluded that there is only one necessary quirk (hp_mute_led), so this patch removes the conflicting one.

[alsa-devel] Alsa Pulse plugin pcm->ptr initialization problem
by Dake Gu 16 Apr '09

16 Apr '09

Hi all, By looking through the pcm_pulse.c(1.0.18), I found there is a possible error in initializing the pcm->ptr. Some background: see update_ptr() function in pcm_pulse.c: Basically the pcm->ptr is increased when pa_stream_writable_size() increases. The last pa_stream_writable_size() is saved in pcm->last_size, so if new pa_stream_writable_size() value is larger than pcm->last_size, the pcm->ptr is increased. For example, the pa_stream_writable_size() increases from 800 to 1400, then pcm->ptr is increased by 400. Alsa-lib's snd_pcm_ioplug_hw_ptr_update() function is calling pulse_pointer() to get pcm->ptr, then pcm_ioplug.c calculates the hw.ptr from the changes of pulse_pointer(). The hw.ptr is used in snd_pcm_mmap_playback_avail(). However, there is an issue that during the pulse is started, the pcm->last_size jumps from 0 to a positive value, which should not be counted as pcm->ptr increase. It's causing the hw.ptr wrongly calculated. Wrong senario pa_writable (N/A) 1000 900 800 1200 pcm->ptr 0 1000 1000 1000 1400 ..... hw.ptr 0 1000 1000 1000 1400 Correct scenario: pa_writable (N/A) 1000 900 800 1200 pcm->ptr 0 0 0 0 400 ..... hw.ptr 0 0 0 0 400 If hw.ptr is incorrectly set larger than actual size, it causes avail>"real avail" and client sends more data than pulse can accept.

[alsa-devel] [PATCH] ASoC: pxa-ssp: allow setting of dai format 0
by Daniel Mack 16 Apr '09

16 Apr '09

pxa_ssp_set_dai_fmt() currently has an early exit if the desired format equals the current configuration. This is correct behaviour unless this function is called with a zero value parameter for the first time. Zero is a valid value for this function, but the early exit is bogus in this case. Hence, set priv->dai_fmt to -1 in the beginning so we can configure the port.

This happened once before, a couple of weeks ago, I think. Then header updates came out of the Ubuntu-Jaunty repository, and then the problem went away. I wish I had been paying more attention to what happened. Susan
