This patch offsets channel -2 correctly from the LR clock. This ensures that channel 2 doesn't loose -any bits during capture. It also results in both channels 1 and 2 having -the same volume. This commit also adds 8 kHz operation. - -Signed-off-by: Matt Flax <flatmax@flatmax.org> ---- - sound/soc/bcm/audioinjector-pi-soundcard.c | 16 +++++++++------- - 1 file changed, 9 insertions(+), 7 deletions(-) - ---- a/sound/soc/bcm/audioinjector-pi-soundcard.c -+++ b/sound/soc/bcm/audioinjector-pi-soundcard.c -@@ -30,7 +30,7 @@ - #include "../codecs/wm8731.h" - - static const unsigned int bcm2835_rates_12000000[] = { -- 32000, 44100, 48000, 96000, 88200, -+ 8000, 16000, 32000, 44100, 48000, 96000, 88200, - }; - - static struct snd_pcm_hw_constraint_list bcm2835_constraints_12000000 = { -@@ -55,19 +55,21 @@ static int snd_audioinjector_pi_soundcar - - switch (params_rate(params)){ - case 8000: -- return snd_soc_dai_set_bclk_ratio(cpu_dai, 1508); -+ return snd_soc_dai_set_bclk_ratio(cpu_dai, 1); -+ case 16000: -+ return snd_soc_dai_set_bclk_ratio(cpu_dai, 750); - case 32000: -- return snd_soc_dai_set_bclk_ratio(cpu_dai, 378); -+ return snd_soc_dai_set_bclk_ratio(cpu_dai, 375); - case 44100: -- return snd_soc_dai_set_bclk_ratio(cpu_dai, 274); -+ return snd_soc_dai_set_bclk_ratio(cpu_dai, 272); - case 48000: -- return snd_soc_dai_set_bclk_ratio(cpu_dai, 252); -+ return snd_soc_dai_set_bclk_ratio(cpu_dai, 250); - case 88200: - return snd_soc_dai_set_bclk_ratio(cpu_dai, 136); - case 96000: -- return snd_soc_dai_set_bclk_ratio(cpu_dai, 126); -+ return snd_soc_dai_set_bclk_ratio(cpu_dai, 125); - default: -- return snd_soc_dai_set_bclk_ratio(cpu_dai, 126); -+ return snd_soc_dai_set_bclk_ratio(cpu_dai, 125); - } - } - |
