TurboniumX Inspire Audio Fix
Confirmed working! Returns tinny audio to stock quality.
Confirmed working! Returns tinny audio to stock quality.
I have only tested with CM7, however it has been reported to work on other ROMs. Please make a backup before attempting this.
I've attached a ZIP that can be flashed from ClockworkMod. All you need to do is take a backup, then flash the ZIP. If it works for you, feel free to buy me a beer!
Original post follows:
I think I may have fixed the tinny sound issue on my Inspire (at least it sounds good to me now). I need someone else to test it though since I only have the one device and only a few people willing to talk to me 10 times in a row. Don't get your hopes up!
In the /system/etc/soundimage directory on a stock ROM there are several files that end in "_MCLK.txt". I pushed these files with adb to /system/etc/soundimage on my Inspire 4G running CM7 nightly build 8 with the Inspire kernel provided over at CM's site. I used Stock_Inspire4G_Rooted_r34p3rex_v01.zip as my "stock ROM".
Then I copied the /system/etc/CodecDSPID_MCLK.txt file from the stock ROM to my device and overwrote the /system/etc/CodecDSPID.txt file. Reboot and it appears to have eliminated the tinny sound for me.
Can someone test this and see if it fixes the issue for you? You'll need to get the files from a stock ROM since I can't post download links yet. Here are some instructions:
Make sure the phone is in USB Debug Mode.
Code:adb shell mount -o remount,rw -t ext4 /dev/block/mmcblk0p25 /system adb push Sound_Bass_Booster_MCLK.txt /system/etc/soundimage/ {repeat above line for each file that starts with 'Sound', should be 27 of them} adb push CodecDSPID_MCLK.txt /system/etc/ adb shell mv /system/etc/CodecDSPID.txt /system/etc/CodecDSPID.orig adb shell mv /system/etc/CodecDSPID_MCLK.txt /system/etc/CodecDSPID.txt
Then reboot.
