[alsa-devel] [PATCH 0/4] ASoC: TWL4030: Gain control updates, adding pre-DAC routing controls
by Peter Ujfalusi 01 Dec '08

01 Dec '08

Hello, This series adds 'proper' gain controls for: Per-DAC common gain controls. There are three gain controls asspciated wit a DAC in TWL, There are four DAC can be used (in OPT_MODE=1). Digital fine gain, Digital coarse gain, Analog gain. Every output, except the HandsFree has their own gain controls per channel (L/R) Pre-DAC routings: Digital input namings: SDRL1: TDM #1 SDRR1: TDM #2 SDRL2: TDM #3, I2S Left SDRR2: TDM #4, I2S Right Mono mixing: SDRM1: mixed SDRL1 and SDRR1 SDRM2: mixed SDRL2 and SDRR2 The possible mux settings for the DAC inputs: DACL1 <- SDRL1, SDRM1, SDRM2, SDRL2 DACR1 <- SDRR1, SDRM1, SDRM2, SDRR2 DACL2 <- SDRL2, SDRM2 DACR2 <- SDRR2, SDRM2 --- Peter Ujfalusi (4): ASoC: TWL4030: Change the capture volume control to TLV ASoC: TWL4030: Change the common playback volume controls ASoC: TWL4030: Add volume controls for outputs ASoC: TWL4030: Add pre-DAC digital mux controls sound/soc/codecs/twl4030.c | 59 ++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 59 insertions(+), 0 deletions(-)

[alsa-devel] Help with Creative's X-Fi drivers
by James Pearson 01 Dec '08

01 Dec '08

I know the ALSA team don't support Creative's X-Fi drivers, but maybe someone could help with this issue: I've managed to 'backport' Creative's recently GPL'd drivers to run on a CentOS4 kernel with ALSA 1.0.15 - the changes to the code were minor, but one thing I'm not sure about is, in ctpcm.c it has: static int ct_pcm_timer_stop(struct ct_atc_pcm *apcm) { unsigned long flags; CTDPF("%s is called\n", __func__); spin_lock_irqsave(&apcm->timer_lock, flags); apcm->stop_timer = 1; del_timer(&apcm->timer); spin_unlock_irqrestore(&apcm->timer_lock, flags); try_to_del_timer_sync(&apcm->timer); return 0; } The CentOS4/RHEL4 2.6.9 kernel doesn't have try_to_del_timer_sync() - so, should I replace it with del_timer() or del_timer_sync() ? I'm currently using del_timer_sync() - and the driver works (I get sound out the head phone jack) - is this OK? Thanks James Pearson

[alsa-devel] Restore state around suspend/resume
by Dan Nicholson 01 Dec '08

01 Dec '08

Hi, Currently, suspending the computer via pm-suspend (as done from HAL), causes the ALSA state to be stored and restored via alsactl. Here's what the hook looks like: http://cgit.freedesktop.org/pm-utils/tree/pm/sleep.d/65alsa Is this still necessary on recent kernels? Is there a list of drivers which properly maintain state across suspend/resume? We're trying to cut down on the amount of work done in userspace which slows down suspend cycles. Thanks. -- Dan -- To unsubscribe from this list: send the line "unsubscribe alsa-devel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
